Does Jellyfish Have Tentacles: Amazing Things About Jellyfish
Jellyfish are common marine creatures found all over the world from surface waters to deep sea. They are bell-like in shape with a similar appearance.
Does Jellyfish Have Tentacles?
Some species are endowed with very long tentacles although they do not sting because of their slippery nature but are capable of stinging other jellyfish species. It grows 15 tentacles from each side of the bell with 10 feet in length.
Does Jellyfish Have Tentacles Or Tendrils?
Most jellyfish are sedentary drifters and slow swimmers because their shape is not hydrodynamic.
Most of them have a tendril or what you can call oral arms coated with thousands of microscopic nematocyst.
How Many Tentacles Does A Jellyfish Have ?
A jellyfish has up to 15 tentacles, it grows around the bell with 10 feet in length with each tentacle about 5,000 venomous cells.
Jellyfish is sworn to stinging action not by touch but by the chemical reaction from its prey’s outer layer. So you can say they’re sensitive creatures.
Do Jellyfish Eat Seaweed?
Jellyfish are carnivorous animals therefore, they consume seaweed such as larvae and any small water creatures they float across.
Jellyfish do not have a specific diet but eat based on their size. Some sea creatures do not eat seaweed because of its tough digestion technique.
Meanwhile, bigger jellyfish preys on bigger sea animals like shrimp, fish and some eat their fellow jelly.
How Long Do Immortal Jellyfish Live ?
Aging is part of every living characteristic therefore the thought of growing old can not be over-emphasized.
Both human beings and animals are prone to aging. But there are rare cases of animals that beat morality of which a jellyfish is one.
To date, Turritopsis jellyfish has been the only biologically proven creature that has the natural ability to outlive death.
This species is a tiny water-based creature that can turn back to its initial stage of life when faced with the threat instead of perishing.
It typically turns back by reverting to its earlier stage of life.
Is Jellyfish A Zooplankton ?
Plankton is a Greek word meaning “drifter”. The word zooplankton is used for an animal that lives as a drifter in either fresh or salty water.
It finds it difficult to survive on hard surfaces. Zooplankton is a weak swimmer but swims a long distance.
Jellyfish is one of the zooplankton family there, it varies in size and swimming ability, unlike fish.
Gelatinous zooplankton is another type of jellies. This type retains a soft and transparent body, it dwells in the water banks as a drifter for as long as it lives. Examples are jellyfish, comb-jellies, and worms.
Do Jellyfish Eat Shrimp ?
Frequently we ask what do jellyfish eat or how do they grow? Shrimp is one of the best meals jellyfish eat to survive, life baby brine shrimp or frozen ones all go down well with a jellyfish. Their growth depends on their eating proficiency.
Amazing Things Jellyfish Are Known For :
Jellyfish are invertebrates, planktonic marine members of a class known as Scyphozoa (phylum Cnidaria), with about 200 species.
Some of its species are box jellyfish, true jellyfish, stalked jellyfish, and small jellyfish. Few species of jellyfish are bigger than a human being, while some are as tiny as needles-eye.
Jellyfish are one of the most colorful creatures ever liveth with their mesmerizing hues, they are similarly the most dangerous marine mammals.
Just 5% of jellyfish bodies are made of proteins, muscles, and cells. The remaining 95% are made of water therefore, it evaporates in a twinkle of an eye when it comes out of water for some reason.
Here are some point to note about Jellyfish:
• Jellyfish predates dinosaurs
• Jellyfish are brainless
• Double name called medusa
• Immortality feature
• They pass waste where they eat
• They have a collective name
• Jellyfish are a deadly creature
• They vary in size
• Jellyfish are edible
• Jellyfish are heartless
• Jellyfish can clone
• Jellyfish have been to space
• Sexual reproduction
• A dead jellyfish stings.
1. Jellyfish predates dinosaurs.
Fossils are hard to come by because jellyfish are boneless, but it’s scientifically proven that jellyfish have been in existence for about 500 million years before dinosaurs.
2. Jellyfish are brainless.
Jellyfish can adapts quickly to change in their environment, therefore, waving with the ocean’s currents. Their body can easily evaporate when washed ashore because it contains 98% of water.
3. Double name called medusa.
Jellyfish with tentacles all around the edge often look bell-like in shape. This shape is called evil Medusa in Greek mythology. Hebrew and French also refer to jellyfish as medusa in their language.
4. They aren’t 100% fish.
One glance at a jellyfish and it’s apparent that they aren’t fish. They are invertebrates from phylum Cnidaria and they vary hence some scientists take to refer to them as “gelatinous zooplankton.
5. Immortality feature.
It’s established that one of a jellyfish species called Turritopsis nutricula can outlive death. This species undergoes what we call “cellular transdifferentiation” a renewer of an organism’s cells when in danger.
In other words, this species is scientifically immortal because of its in-built fountain of youth.
6. They pass waste where they eat.
It may look absurd but jellyfish have no special organ to eat and poop. They pass waste from the same organ they eat, that’s because their mouth and anus are located in the same place.
7. They have a collective name.
Each group of animals even humans, living and non-living things have different collective names, jellyfish aren’t left out.
While a group of dolphins is called a pod, a group of fish is called a school, a group of jellyfish has multiple names. It can be called a bloom, swarm, or smack.
Isn’t that beautiful?
8. Jellyfish is a deadly creature.
All species of jellyfish have a stinging structure called nematocysts but the stinging power varies depending on the species involved. Box jellyfish is the most deadly and venomous among its species.
Its capable of killing humans in less than a minute, each box jellyfish carries enough venom to kill more than 60 humans. It’s reported that their sting alone could kill before the venom because of how painful it is.
9. They vary in size.
Some jellyfish are extremely tiny in such a way that they often become unnoticed while floating in the Ocean’s currents while some are very big.
The world’s largest jellyfish are “The lion’s mane jellyfish” Cyanea capita, which is also the longest with 120 feet tentacles.
Nevertheless, the world’s biggest jellyfish by the virtue of weight and diameter is the titanic Nomura’s jellyfish which can stunt a human diva.
10. Jellyfish are edible.
It might not be noticeable in restaurants like other fishes but it’s proven that some species of jellyfish are edible with nutritional values.
Japan and Korea are two countries where jellyfish are best eaten as a special delicacy.
Japan produces jellyfish-made candy, caramel made out of sugar, and jellyfish powder by their students. We have over 25 edible types of jellyfish.
11. Jellyfish are brainless.
You may be wondering how this animal lives without a heart, lung, and brain this is a crucial organ of the body.
They have very tiny skin that absorbs oxygen directly through them. So they have no blood but dwell well underwater.
Jellyfish are sensitive to touch hence the zero need of the brain to process it.
12. Ability to clone.
Imagine how beautiful it would have been if you can split yourself into two equal parts to make another version of yourself! That is one unique feature of a jellyfish.
If a jellyfish is cut into two, the two parts regenerate to form two new jellies.
13. Jellyfish have been to space.
Over 2000 species of jellyfish known as moonfish traveled to outer space in 1991 on a space shuttle Columbia.
The space-produced jellyfish couldn’t cope with Earth’s gravity when they returned as scientifically proven. This shows the microgravity’s effects on them.
14. Mythical treatment.
Some myths and superstitions believe that urine can cure jellyfish Venuareis not real.
If by mistake you are accidentally stung by a jellyfish, the best way to treat yourself is by taking off the tentacles with tongs then soak it in a hot water.
Or better yet, seek medical attention as soon as possible before the Venum goes to the heart.
15. Sexual reproduction.
Like every other living thing, a jellyfish reproduces sexually. It releases eggs and sperm inside the ocean, where after some time, they transform into tiny swimming larvae.
These larvae in turn develop into what is called polyps. These polyps then stick to a flat surface where it spreads into multiple jellies.
16. A dead jellyfish stings.
You may be marveling at how possible It is for a dead cell to sting? Among all sea creatures, jellyfish are unique with their extraordinary features. Even at death, jellyfish tentacles are as active as they are before death.
In conclusion, Jellyfish have been recorded to be one if not the oldest marine animal ever liveth because of the absence of fossil in them. To know more fact about jellyfish, contact us today.
