1) Some jellyfish can glow in the dark
Many jellyfish have glowing bioluminescent organs. This
light can help them in many ways, such as attracting prey or distracting
predators.
2) Some jellyfish are immortal
Jellyfish life is divided into two stages: fixed polyp stage and floating jellyfish stage. When talking about jellyfish, it usually refers to the Medusa stage. Normally, jellyfish develop from polyps to Medusa, but Turritopsis nutricula is nicknamed "Immortal Jellyfish" for being able to return to the polyp stage when stressed.
3) Jellyfish can teach us effective underwater propulsion
The movement of the bell jellyfish gave researchers a new
understanding of advancement. The flexibility of the umbrella body allows them
to pulsate up and down without consuming a lot of energy. Researchers have
created bionic robots with flexible bells that may one day bring better
submarine vehicles.
4) Jellyfish can clone themselves
If the sea is cut in half, the fragments of sea jellyfish can regenerate and produce two new creatures. Similarly, if a jellyfish is injured, it may clone itself and may produce hundreds of offspring.
5) There is a huge jellyfish called pink little girl
The scientific name of this jelly is Drymonema larsoni, but
its aggressive sting and unique color have earned it the nickname "Pink
Little Animal".
6) Jellyfish has no brain
In contrast, jellyfish have neural networks that can sense
changes in the environment and coordinate animal responses.
7) The jellyfish movement has inspired a new way of flying
It is not surprising that the jellyfish became the
inspiration for swimming robots. However, it is even rarer to see marine
life-inspired aircraft, but this is what happened at New York University.
8) Jellyfish powder has
been used to make salted caramel
Turtles eat jellyfish, large jellyfish may eat small
jellyfish, but is jellyfish suitable for human consumption? A group of high
school students in Japan came up with a salted caramel recipe using powered
jellyfish. It is not a vegan, but it is a way to deal with invasive jellyfish.
9) Glowing jellyfish can power medical equipment
Another jellyfish-derived product uses jellyfish's
fluorescent protein, which can be used to power medical devices in the future.
10) Jellyfish are surprisingly good at shutting down
nuclear reactors
Over the past decade, the proliferation of sea blooms has
led to the shutdown of several nuclear reactors, which often rely on the intake
of seawater. Jellyfish colonies can block the inlet pipes, forcing the facility
to temporarily stop running.
11) Jellyfish will eat peanut butter
Peanut butter jellyfish! Need me to say more?
Okay, I will: Two aquaculture farmers in Dallas, Texas,
created a brine / peanut butter mixture and fed it to moon cakes. Clearly, Jellyfish found this mixture to be an acceptable source of protein. The researchers
wrote: "We are happy to declare that the purpose of our experiment is
noble, but the fact is that we just want to make peanut butter and jellyfish
just to see if we can do it."
12) Jellyfish is almost entirely composed of water - About
5% of jellyfish are made up of structural proteins, muscle and nerve cells,
while the remaining 95% is water. In contrast, the body's water content is as
high as 60%.
13) A group of jellyfish can use three different
names - The fauna usually has its own name:-Heard a group of cows, for example,
many fish swimming together is a school. Jellyfish groups can be represented by
three different names. A group of jellyfish is called "bloom",
"snacks" or "herds."
14) Jellyfish are not fish at all - Despite the name
of the jellyfish, it is not a real fish. Fish are vertebrates that live in
water and breathe through and. On the other hand, jellyfish are invertebrates,
which means they have no skeleton, and they absorb oxygen from the water
through the membrane.
15) There are more than 25 kinds of edible jellyfish
- Jellyfish can be delicacies-there are over 25v edible jellyfish. They are
usually found in salads or picked. Some people say that their salty taste is
similar to the consistency of noodles.
16) Jellyfish can be found in all seawater - Because
jellyfish tend to follow the tide of the ocean, they can be found in various
seawaters around the world. They can thrive in warm tropical water or cold
arctic water. They were found near the seabed and the surface.
17) Jellyfish eat other marine life - Jellyfish usually eat small
plants, shrimp or fish, and then use their tentacles to stun the prey before
they are eaten.
18) Some jellyfish are bioluminescent - Bioluminescence is the term for the ability of organisms to produce their own light. Some jellyfish produce this light and produce internal halos.
19) The size of the jellyfish ranges from the rubber
tip of a thimble or pencil to about 8 feet in diameter, and the antennae can
reach 200 feet. Just two blue whales.
20) Each jellyfish tentacle contains thousands of
cells called "cells." Inside the nucleated cells are nematode sacs,
and each cyst contains a coiled barbed wire. When fish or other objects become
entangled in the tentacles, the pressure in the nematode sac unleaps the
poisonous thread like a spring harpoon.
21) The main defense mechanism of jellyfish is
stabbing and transparent body, which makes it easy to hide.
22) Though jellies are soft-bodied and lack a
skeleton, making fossils rare, there is evidence that jellyfish predate
dinosaurs by some 400 million years.
23) Many neurosurgeons say that popular treatments
for tingling, such as vinegar, urine or meat tenderizers, are not helpful for
treating tingling. Instead, the best way is to get it out of the water
immediately and wash the affected area with salt water (do not use fresh
water). Salt water will inactivate stinging cells, and fresh water or tap water
will activate them. The best way to delete a cell is to use something like a
credit card.
24) Jellyfish has a short tube hanging from its body.
The tube acts as both a mouth and a digestive tube. In some jellyfish, the
central tube is surrounded by pleated fragments that look like curly ribbons in
water. These are called oral arms or mouth arms.
25) Jellyfish have no brain, heart, ears, head, feet,
legs or bones. Their skin is very thin and they can breathe.
26) Although jellyfish do not have a brain, they have
a basic nervous system, and their receptors can detect light, vibration and
chemicals in water. These functions and the sense of gravity allow jellyfish to
orient and guide themselves in the water.
27) Jellyfish are invertebrates, which means they are
animals without bones. About 95% of their bodies are water.
28) Jellyfish are usually found in shallow coastal
waters; however, scientists have discovered some species that live at a depth
of 30,000 feet (9,000 meters). Although most jellyfish like warm water, some
aquatic animals live below the Arctic.
29) The jellyfish tentacle will still sting even if
it is separated from the jellyfish body.
30) The smallest jellyfish in the world is a bell-shaped disk with a diameter from 0.5 mm to a few mm.
It reproduces vegetatively by splitting in half. Another competitor to the
smallest jellyfish is the highly toxic Australian Irukandji, which is only the
size of a nail.
31) The largest jellyfish in the world is the
jellyfish in Nomura. Other candidates for large jellyfish are the lion's mane
jellyfish and the giant mouth king.
32) In the past 110 years, I have only seen giant
jellyfish 17 times, namely giant beak.
33) Portuguese soldiers look like jellyfish, but not
real jellyfish. In fact, it is not even an animal. It is a kind of siphon, an
animal composed of a group of creatures working together. Specifically, the
"War Man" consists of four independent polyps. The polyp at the top
is a gas-filled bladder, reminiscent of the sails on an ordinary ship that was
once a battleship.
34) Asexual and sexual reproduction of jellyfish.
They are usually male or female, although hermaphrodites are also found.
35) The life span of jellyfish varies from a few
hours to several months. According to reports, the lifespan of a species is up
to 30 years. Jellyfish in aquariums usually live longer than in the wild.
Because jellyfish are very fragile, it is easier for people to catch jellyfish
at the polyp stage when the polyps are most vulnerable.
36) Most jellyfish are passive carnivores. They feed
on plankton, crustaceans, other jellyfish, fish eggs and small fish. They feed
and empty through the same hole in the bell.
37) There are several predators of jellyfish,
including other jellyfish, sharks, tuna, swordfish, turtles and a type of
Pacific salmon.
38) A jellyfish, Turritopsis nutricula, is also known
as "eternal jellyfish" because it can change from a mature Medusa
state back to a polyp state, thereby basically avoiding death. It achieves this
goal through a cell development process called trans differentiation.
39) The most common jellyfish on the coast of North
America and Europe is the moon jellyfish. This jellyfish is usually blue or
pink and is found in waters about 20 feet (6 meters) deep. Its stinging is
usually mild, but it will leave an itchy rash.
40) Even dead jellyfish can sting.
41) Jellyfish have lived in the waters of the world
for more than 650 million years before the dinosaurs, making it the oldest
multi-organ animal.
42) Portuguese combatants can grow to 165 feet (50
meters) long, although more typically 30 feet. On baseball diamonds, they will
go from home run to first base, then more than half reach second base.
Sometimes wars can be observed in groups of 1,000 or more in warm water. To
avoid threats, they can put air bags and sink briefly underwater.
43) The inverted jellyfish will not float in the
water. Instead, it anchors itself with its short arms and tentacles reaching
the bottom of the sea. It looks like a bowl of plants, not a typical jellyfish.
44) Sometimes I see crabs riding a jellyfish
hitchhiker. The hard shell of the crab protects it from the sting of jellyfish.
Crabs also often catch small amounts of food caught by jellyfish.
45) There are more than 2,000 different types of
jellyfish. Boxed jellyfish (Chironex fleckeri) is the most dangerous, and about
70 people will be injured. Scientists believe that there may be as many as
300,000 different jellyfish species yet to be discovered.
46) Jellyfish are not fish. They are actually
plankton of the Cnidaria phylum (Greek for "stinging nettle") and the
Scyphoza class (from the Greek "cup"). Some aquariums are trying to
promote the term "jellyfish" or "jellyfish" instead of
jellyfish.
47) Jellyfish basically move in two ways. They picked
up the water in the bell and sprayed it behind them, forming a stream of water
and moving it forward. They also drift with the current.
48) The body of the jellyfish has six parts. The
inner layer is the gastric mucosa, which is located in the cavity of the
gastric blood vessel. The middle layer is a thick substance called mesoderm.
The outer layer is the epidermis. It also has an orifice and tentacles.
49) Researchers believe that the shipping industry
has artificially distributed jellyfish into non-native habitats and then
settled here. Ships transport jellyfish around the world in two ways: 1)
juvenile jellyfish (polyps) attach to the hull and travel with them; 2) the
ship receives ballast water at the port of departure and then dumps its ballast
water (and jellyfish and Other creatures) in new waters. Billions of gallons of
ballast water are transported worldwide every year.
50) Jellyfish are aggressive colonists. In 1982,
eight years after the introduction of comb jellyfish into the Black Sea, their
total volume was about 900 million tons. Jellyfish caused $ 350 million in
damage to the Black Sea ’s fisheries and tourism.
51) Environmental pressure may increase the jellyfish
population. Jellyfish is one of the very few organisms that can adapt to dead
areas in the ocean or areas with little oxygen and pollution. There are more
than 400 marine dead zones in the world.
52) A group of jellyfish called flowers, swarms or
spots.
53) The sea bloom near Japan can hold more than 500
million sea lyes, each of which has the size of a refrigerator.
54) After the jellyfish plunged into the cooling
system, it has been responsible for temporarily shutting down nuclear power
plants in Japan. The Japanese refer to these jellyfish as Echizen Kurage, or in
English as the jellyfish of Nomura.
55) The weight of jellyfish is more than 10 times
that of the fish caught every year in the world.
56) About 150 million people in the world come into
contact with jellyfish every year. About 200,000 people are stung every year in
Florida, and about 500,000 people around Chesapeake Bay.
57) Many scientists believe that environmental stress
factors (including climate change, pollution, overfishing of fish and dams)
have caused the spread of jellyfish.
58) Harvest the collagen in jellyfish. Collagen can
be used for many purposes, including the treatment of rheumatoid arthritis.
59) In 2007, the jellyfish flourished and the salmon
farm in Northern Ireland was killed, killing more than 100,000 fish.
60) Jellyfish belong to Beatenia. All animals in this
group are radially symmetrical. Other animals in this category include water
snakes, anemones and corals.
61) In some parts of the world, jellyfish are
considered delicious. For example, in Malaysia, people call them "dental
music". Each year, it eats hundreds of metric tons of sea and sells for
15 dollars per pound, which makes it a multi-million dollar business. The most
commonly eaten jellyfish is shell jellyfish.
62) In 2002, an American tourist died after being
injured by the fatal Irukandji jellyfish near the Great Barrier Reef in Australia.
This jellyfish is only the size of a thumbnail, but can have three-foot
tentacles. Most jellyfish have staves on their antennae, but Irukandji
jellyfish also have staves on their bells.
63) An adult jellyfish is named "Medusa"
(plural "medusae"), named after the snake of the Greek monster
Medusa.
64) In the 2008 movie "Seven Pounds", IRS
agent Ben Smith played by Will Smith committed suicide and shared a bathtub
with a deadly jellyfish. The title refers to the "seven ponds" of
meat that Will Smith gave to others to make up for the loss of killing seven
innocent people in a car accident.
65) Jellyfish digest food quickly. If they must carry
a lot of food, it will be difficult to float.
66) The venom in a single box of jellyfish can kill
60 people.
67) Jellyfish kill more people than sharks each year.
68) Different jellyfish give birth in different ways.
Some jellyfish eject eggs from their mouths to fertilize them in vitro. Others
leave the eggs in their mouths until they develop enough to live alone.
69) Most jellyfish have two basic stages of life. In
the first stage, they are called polyps and grow by growing buds like plants.
Then, the polyps sprout from the tender jellyfish. After a few weeks, laver
will become an adult jellyfish or jellyfish.
70) Jellyfish consist of more than 95% water. If they
are removed from the water, they will collapse and die.
71) The boxed jellyfish is unique because it has 24
eyes, four parallel brains, and 60 anal areas. Its two eyes can see the color.
It is also one of the animals in the world that can observe the surrounding
environment in 360 degrees. Boxed jellyfish are not considered to be
"real" jellyfish of the Scyphozoan type.
72) Jellyfish staying near the sun on the water
surface are often colorless. The jellyfish swimming deeper are usually red,
purple, green, yellow, and sometimes may even have stripes.
73) A military mechanical jellyfish has been created
to perform search and rescue and investigation tasks. Silicone
"Robojelly" uses hydrogen and oxygen as fuel when swimming, so the
only "exhaust gas" is heat and water. Its muscles are made of shape
memory alloy, which is a metal invented by NASA to "remember" its
original shape.
74) The jellyfish crest that looks like a mushroom
crest is called a bell shape.
75) Scientists divide real jellyfish and boxed
jellyfish into two different groups. The real jellyfish is a dolphin, meaning
"bowl animal". The box jellyfish is a cubic animal, meaning
"cubic animal". The real jellyfish clock is round like a bowl. The
jellyfish bell in the box has sides and rounded corners, and is shaped like a
box.
76) Scientists have developed anti-snake venom for
box jellyfish. In Australia where boxed jellyfish live, ambulances and
hospitals can save life-saving venom anytime, anywhere.
77) The lion's mane jellyfish is the largest of the
true jellyfish, with a tentacle length of up to 120 feet (36.6 m). Its bell can
span up to 7 feet 6 inches (2.3 m). It lives in oceans around the world and
feeds on small fish, shrimp and other small jellyfish. Its sting is painful,
but it is not fatal to humans.
78) The deadliest and most toxic marine life in the
ocean is the boxed jellyfish, also known as "marine stinger" and
"sea bee".
79) In Australia, an average of 1 person is killed by
boxed jellyfish each year. Boxed jellyfish may kill up to 100 people each year
in other parts of the world (such as the Philippines, Indonesia, and Thailand).
80) Both real jellyfish and boxed jellyfish use their
thorny tentacles to grab shrimp and small fish as food. However, boxed
jellyfish are active hunters, mainly because they have eyes, not real
jellyfish. They are also better swimmers. Boxed jellyfish can swim at 4 miles
per hour, which is faster than most people can swim.
81) Unraveling the jellyfish's little ing son is one
of the fastest moves in nature. The stinger's firing speed is even faster than
the bullet's firing speed.
82) Boxed jellyfish may cause a person to stop the
heart beat in about two minutes.
83) They defecate at the place where they eat.
It may not sound appetizing, but jellyfish do not
need a separate hole to eat and defecate. They have an orifice that can do both
oral and anal tasks.
84) Their mouth is located right in the middle of
their body and is used to eat, discard waste and push themselves forward by
spraying water into it!
85) Jellyfish can eat anything, including fish,
shrimp, crabs, tiny plants, plankton and other jellyfish!
86) They themselves were eaten! Turtles like to
devour jellyfish, and so are humans in some parts of the world! They are
considered as delicacy in China and also used in Chinese medicine.
87) Unfortunately, the jellyfish life is not long,
ranging from a few hours to a year.
88) Not all jellyfish have tentacles, but their
tentacles are often used to capture and fix prey.
89) Jellyfish are not fish at all. Although they have
a name, they are actually invertebrates because they have no backbone.
90) They come in various shapes and sizes, ranging
from 2 cm to 2 m! Some are transparent or translucent and difficult to see,
while others are bright colors (such as pink, blue, purple and yellow) that are
dazzling.
91) Some jellyfish's tentacles will sting. Although most are harmless to humans, they may be extremely toxic and very painful, and even fatal. For safety reasons, if you find jellyfish in the water, always pay attention to the surrounding environment.
92) Jellyfish are like zombies and have no brains!
Well, now it becomes very scary. They have a neural network of the brain
instead of the brain, which can sense changes in the surrounding environment
and guide its response. In addition, jellyfish have no heart, bones or eyes.
93) Speckled jellyfish: Another bell-shaped jelly.
The spotted jellyfish is usually golden and up to 12 inches in diameter,
although the average size is about 4 inches. A strange fact about these
jellyfish is that they have multiple mouths on their arms to catch the small
plankton they eat. Although they do have stings, the venom is so mild that it
does not cause problems for humans.
94) Moon jellyfish: Although they can grow to 10 to
16 inches in diameter, moon jellyfish have only mild stinging cells. If the
boxed jellyfish resembles the sting of a bee, then the moon jellyfish is more
like a mild ant bite. You may feel it, but there is no injury.
95) Jellyfish can be seen.
If you look very closely at the edge of the jellyfish
umbrella, you will find a small organ called rhopalia. They contain the sensory
structure of jellyfish: not only light organs, but also balance organs, current
sensors and chemical receptors. The box jellyfish has four horizontal stripes,
each with only 6 eyes, for a total of 24. There are eight fully functional
lenses, a retina and an iris. The iris will brighten and darken like our iris.
96) Jellyfish spend all their time searching for
food, escaping predators or looking for partners
97) The life span of jellyfish is very short: some
small species can only survive for a few hours, while the largest species, such
as lion's mane jellyfish, can survive for several years.
98) The jellyfish hatch from the egg, the female
discharges the egg into the water, and then the male fertilizes it. What came
out of the egg was a free-living plankton.
99) Pay attention to jellyfish on the water and the
beach. Even the tentacles separated from the jellyfish can sting.
