Oral Arms


We just learned about the Manubrium mouth on a jellyfish.

Another part of a jellyfish's body is the Oral Arms.

We learned that the manubrium is the mouth.
The oral arms are connected to the manubrium, and they hang down below the jellyfish like tentacles.
When they sting an animal, the oral arms help bring the food up to their manubrium mouth so they can eat it.

Manubrium


We just learned about the Gastrodermis that helps the jellyfish eat.

Another part of the jellyfish's body is the Manubrium.

This is a part that hangs down from the middle of the inside of the jellyfish.
They use it to eat, and also to get rid of waste.

Gastrodermis


We just learned about the jellyfish Mesoglea underneath the bell.

Another part of a jellyfish's body is the Gastrodermis.

This is the part below the mesoglea.
The gastrodermis helps the jellyfish digest the food that gets brought up to their mouth.

Mesoglea


We just learned about the Jellyfish - Epidermis.

Another part of the jellyfish body is the Mesoglea.

Underneath the bell part of the jellyfish is an open area that is made up of water and some other gooey stuff called collagen.
It's almost like a balloon full of jelly that helps the jellyfish keep it's shape in the water.

Jellyfish Epidermis


We just learned about the Jellyfish Bell.

Another part of the jellyfish is the Epidermis.

The epidermis is the skin on the outside of the bell.
Just like humans, jellyfish have skin, and their epidermis has a bunch of nerves in it called a "nerve net".

This nerve net helps them feel movement in the water and tell their body where to try and swim to get food.

Marrus Orthocanna


We just learned about the Green Hydra.

Another type of hydrozoan is the Marrus Orthocanna.

This animal looks like a long fiery string with bubbles on it.
It can grow to be several feet long, and forty inches wide.

These creatures live in very deep waters, over 600 feet deep and mostly in the Arctic Ocean.

Green Hydra


We just learned about the String Jellyfish.

Another type of hydrozoan is a Green Hydra, also called the Hydra Viridissima.

These are skinny green animals with tentacles, that are very small, only about 10 milimeters.

They eat tiny little insects and crustaceans.

Green Hyrdras mostly do not swim around anywhere and usually just live on top of other things in the water like plants.

Their green color comes from a type of green algea that grows on their body.

They can flex their body a little to move around if they have to, but mostly they just stay on the plant they are attached to.

String Jellyfish


We just learned about the Freshwater Jellyfish.

Another type of animal is the String Jellyfish, also called the Barbed Wire Jellyfish, Long Stringy Stingy Thingy, and Apolemia Uvaria.

Just like some other animals, this looks like a jellyfish but it's actually a hydrozoan.

One String Jellyfish is really a whole bunch of little ones all attached together.

This animal can get up to about 10 feet long, and 2 inches wide.
They live like one big long string with pink and white tentacles.
The tentacles are all different animals stuck together on the one big long string in the middle.

These tentacles do have a painful sting but will not kill a person.

Freshwater Jellyfish


We just learned about the Creeping Comb Jelly.

Another type of jellyfish is the Freshwater Jellyfish, also called the Craspedcusta Sowerbii.

Just like the name says, this jellyfish lives in freshwater, not in saltwater like the oceans.

It comes from China, but it has been found pretty much everywhere in the world, from North America to Australia.

It grows to about one inch wide, and has tiny little tentacles that have stingers to catch its prey, but the stingers aren't strong enough for a human to even feel the sting.

This type of jelly is actually lives on top of a starfish!

They are small and yellow, and they almost look like little worms with strings hanging off of them.

We just learned about the Velella the sea sail hydrozoan.

Another type of jellyfish is the Blue Jellyfish, also called the bluefire jellyfish, Cyanea lamarckii or cyanea nozakii.

This is a small blue or yellow jellyfish grows to about 1 inch wide.
They mostly live around the areas of Europe by Sctoland and England.

Velella


We just learned about the Portuguese Man o' War that looks like a jellyfish but is a hydrozoan.

Another type of hydrozoan is the Velella, also called the sea raft, by-the-wind sailor, purple sail or little sail.

These are small blue animals that float along the top of the water, and have what looks like a little sail on top of their body.

The sail catches the wind and helps these animals move along the water.

They are very small, only about two and a half inches.
Just like other hydrozoans, they are actually a bunch of small animals all stuck together.
They use small tentacles to catch things like plankton with stingers and then eat them up.

The stingers don't hurt humans, but might make their skin itch a little.

Portuguese Man o' War


We just learned about the Blue Button hydrozoan that looks like a jellyfish.

Another animal that looks like a jellyfish but isn't, is the Portuguese Man o' War, also called the pyhsalia physalis or blue bottle.

Just like the blue button, this is a hydrozoan.
The Man o' War has a very powerful venomous sting, and can kill fish or even humans!

They live on top of the water, floating along the surface with the stingers underneath.
The blowing wind and moving water moves these animals along, as they don't have any way to swim.

Sometimes the tentacles of these animals will fall off and go floating off in the water, but they can still sting someone.
Even if these animals float up onto a beach they can still sting.

Usually a sting from the man o' war is like a mark from a whip, and can sometimes cause people to have trouble breathing.

Because they are so dangerous, usually if they are found on a beach it will be closed until they go away.

Blue Button


We just learned about the Bahtrocyroe Fosteri jellyfish.

Another type of sea animal is a Blue Button, also called a Porpita porpita.

Even though this animal looks like a jellyfish, it is in a different family, called hydrozoans.

They live in the ocean in the warm waters by the equator.

The middle part of the blue button is called the float, and it is about one inch wide.
Around the edge are floating arms that look like tentacles, but each one of them is actually it's own animal called a hydroid.
You can almost think of it like a floating colony of ants, all hanging on to a raft.

These blue buttons just float along the ocean and eats on things even smaller than itself that are just floating around.
They do have a sting like a jellyfish, but it is only a little painful.

We just learned about the long clear Venus Girdle Jellyfish.

Another type of jellyfish is the Warty Comb Jelly, also called the Sea Walnut, or the Mnemiopsis Leidyi.

These jellies mostly live in the west part of the Atlantic ocean, and are about 5 inches wide.

They are oval shaped, and they light up with blue-green colors with they get upset.

Venus Girdle Jellyfish


We just learned about the very dangerous Sea Wasp jellyfish.

Another type of jelly is the Venus Girdle Jellyfish, also called the cestum veneris.

This is a very different kind of jellyfish because it looks like a big long clear ribbon with glowing white blue edges.

They can grow to be 1 meter (about 3 feet), and they usually live in the very warm waters of the ocean.

Sea Wasp


We just learned about the Diplulmaris Antarctica.

Another type of jellyfish is the Sea Wasp also called the chironex fleckeri.

Some people call this jellyfish the most lethal jellyfish in the world, because it has caused deaths because of its painful sting.

They mostly live around the north side of Australia, and can have tentacles up to 10 feet long.

Their sting hurts very badly, and after getting stung a person needs to get to a hospital right away!

Luckily because these jellyfish only live in one spot in the world, people know to watch out for them, and try to put warning signs up where they are at in the water.

Diplulmaris Antarctica


We just learned about the White Spotted Jellyfish.

Another type of jelly is the Diplulmaris Antarctica.

Jellyfish live in oceans all over the world, and like you might guess from this one's name it lives near Antarctica at the south pole!

These jellies only grow up to about 7 inches.
They have white tentacles and a mostly white bell.
The inside of the jelly where the stomach is at is a reddish orange color, so it really stands out against the rest of their white body.
It's frilly arms that help bring their food to their mouth are also the same orange red color, so they are pretty neat looking.
