Glass Squid


We just learned about the Parapuzosia.

Another type of cephalopod is the Glass Squid, also known as the cockatoo squid, cranch squid, cranchiid or bathyscaphoid squid.

This type of squid lives in the ocean near the surface or in the middle of the water all over the world.
They are from about 4 inches long to almost 10 feet long.

They get their name because they are almost totally see through, almost like a floating piece of glass!
Because they are so clear, these squids can hide out so that their prey can not see them coming, and their predators can not come eat them.

Parapuzosia


We just learned about the Giant Cuttlefish.

Another type of cephalopod is the Parapuzosia.

This animal is extinct now, but it was part of the ammonite family, which look a lot like the shelled nautilus, but are actually their own family in the world of animals.

These Parapuzosias would grow to be around 2 feet wide, but one person found pieces of an old shell showing one that was over 8 feet tall!

Giant Cuttlefish


We just learned about the Mimic Octopus.

Another type of cephalopod is the Giant Cuttlefish.

This is the largest cuttlefish in the world, and they live around the southern part of Australia.

They are very colorful and can chcange their whole body to white, red or yellow, and very bright or very dark to try and either get the attention of other cuttlefish, or to confuse the animals they are hunting.

They also can raise up little bumps on their skin to make themselves look either bumpy or smooth, so they can look like rocks, sand or seaweed.

The giant cuttlefish is so popular in Australia, that for a festival someone made a 42 foot long parade float shaped like a cuttlefish, named "Stobie the Disco Cuttlefish" that could move its arms, blink its eyes, and had flashing lights and dance music.

Mimic Octopus


We just learned about the Vampire Squid.

Another type of cephalopod is the Mimic Octopus.

This octopus lives on the sea floor, and tries to look like other animals.
It can change it's body color, puff it's head up, wave its arms around or hold its body in a certain way to look like other animals.

Sometimes it will try and look like it's prey like a crab, so that it can sneak up on the crab and eat it before the crab even figures out there is a dangerous octopus nearby.

Other times it will try and look like a poisonous animal like a lionfish, so that predators that might attack the octopus will stay away and not try to eat it.

Theses octopuses have been seen trying to look like a lion fish, sea snake, flat fish, jelly fish, crab or even a sponge!

They are very smart animals, and will decide which animal to try and look like depending on which other animal they meet.
These smart cephalopods have been seen looking like up to 15 different animals!

Vampire Squid


We just learned about the Red Cuttlefish.

Another type of cephalopod is the Vampire Squid.

This type of squid lives in the cold deep part of the ocean, over 2,000 feet below the sea.
It is very cold and dark at this part of the ocean, and there is not a lot of oxygen or food to eat.

Even though they are called the vampire squid, they do not drink blood of other animals.
They eat waste that is floating in the water.

These vampire squids are also kind of like an octopus, so they are their own type of squid and octopus cephalopod called "Vampyromorphida".

Just like the cirroteuthis octopus that looks like it is wearing a skirt, these cephalopods have their arms all webbed together.
Inside their webbed area their arms all have little poky looking spikes called cirri on them.
They are not sharp, and the vampire squid uses them to help collect the garbage food that is floating around in the water.

If they get scared, they can light up their body with photophores that make them glow.
Mostly just at the tips of their arms and the top of their head, but their whole body can make light.
They can also spit out some glowing goo, and sometimes they flip their webbed skirt area inside out and wrap it around their head to try and scare off someone who is trying to eat them.

These cephalopods can have black skin with a red eye, or red skin with a blue eye, so you can see why someone thought they looked like a scary vampire squid!
But mostly they are just a harmless animal floating deep in the ocean eating garbage and trying not to get eaten by a bigger animal.

Red Cuttlefish


We just learned about the Lituites Nautilus.

Another type of cephalopod is the Red Cuttlefish, also called the Reaper Cuttlefish or sepia mestus.

This type of cuttlefish lives in the southern pacific area, and is seen a lot by divers in Australia, hiding out and waiting for prey to come by.

Just like other cuttlefish it has the ability to change to different colors, but for some reason this type of cuttlefish's favorite color is red!

Lituites Nautilus


We just learned about the Argonaut Octopus.

Another type of cephalopod is the Lituites Nautilus.

This is an extinct type of nautilus from long ago that we know about because of fossils found in the ocean.

Just like the Chambered Nautilus it has a coiled body like a type of snail shell, but then it straightens out at the end like the ancient Orthoceras Nautilus we learned about.

Argonaut Octopus


We just learned about the Bigfin Reef Squid.

Another type of cephalopod is the Argonaut Octopus.

These octopuses are sometimes called a "paper nautilus" because the female argonaut will make a hard shell to lay their eggs in, and they will have part of their body in this shell, curled up and looking like a nautilus.

They lay their eggs in the shell, and then sometimes even after the eggs hatch they keep the shell and live in it.

The male argonaut does not have a shell. Both the males and females have eight arms just like all other octopuses.

Bigfin Reef Squid


We just learned about the Flamboyant Cuttlefish.

Another type of cephalopod is the Bigfin Reef Squid.

These squids get their name from the big fin on their mantle that goes all the way around it.
With their shape and the way they swim, sometimes people think they are cuttlefish.

They grow to around 13 inches in just a few months, and they only live for less than a year.

Their body has a lot of different colors, and can be white, yellow, pink, brown or purple.
Sometimes when light is shined on them their body will reflect white, green or red, but they do not glow in the dark like some other cephalopods.

Because these squids grow very fast, there are people out there who try to have squid farms in the ocean, almost like cows, chicken or pigs.

Flamboyant Cuttlefish


We just learned about the Orthoceras.

Another type of cephalopod is the Flamboyant Cuttlefish, also known as Metasepia pfefferi.

These cuttlefish are very small, only about 3 inches long.
They are very brightly colored, and also just as poisonous as the blue ringed octopus!
Like other cuttlefish it has a cuttlebone inside its body that it uses to help it swim, but its cuttlebone is very small, so it mostly just walks around on the bottom of the sea.

It is usually a dark brown color, but when it is attacked it changes its colors to patterns of black, dark brown, white, red and yellow.
When it is walking along the sea floor it waves around its red tipped upper arms to try and tell predators that it is poisonous.

Orthoceras Nautilus


We just learned about the Firefly Squid that can light itself up.

Another cephalopod is the Orthoceras.

This is a type of nautilus that is extinct, which means they aren't around anymore.
We only know they existed because people have found fossils from a long time ago.

They are a type of nautilus, but very different because their body is shaped like a long cone.

Firefly Squid


We just learned about the Cirroteuthis.

Another type of cephalopod is the Firefly Squid also known as watasenia scintillans.
They are usually about 3 inches long, and live in the Pacific Ocean.

This type of squid is bioluminescent.
That means parts of its body light up, kind of like a firefly.

There are tiny little dots all over the squid's body with organs called photophores.
The squid uses these photophores to light up, which makes small fish swim toward them, and they eat them up!

It also uses its body lights to make its top bright and bottom dark so it can hide from other predators.

When it is looking around for another firefly squid it will light up it's whole body as a signal.

Cirroteuthis Octopus


We just learned about the Grimpoteuthis - Dumbo Octopus.

Another type of cephalopod is Cirroteuthis.

This is an octopus that has webbing in between its arms holding them together.
It almost looks like an octopus wearing a dress!

It can grow to be almost five feet long, and is usually white or purple.
Just like the dumbo octopus, this octopus has fins on its head that it can flap.

They live in the deep sea in cold water, like the Arctic ocean or the south pacific near Antarctica.
Scientists have not been able to find a lot of these, because they live over 6,000 feet deep in the ocean, where there is almost no light.

Grimpoteuthis - Dumbo Octopus


We just learned about the Blue Ringed Octopus.

Another cephalopod is the Grimpoteuthis, also known as the "Dumbo Octopus".

This octopus has fins on the side of it's head that look almost like ears, and it flaps these fins almost like dumbo the elephant flapping its ears to fly.
They swim along the ocean floor floating along, and then they jump on their prey and swallow it whole.

Blue Ringed Octopus


We just learned about the Hawaiian Bobtail Squid.

Another type of cephalopod is the Blue Ringed Octopus.

This type of octopus is very small, only about 4 to 8 inches wide even including its arms.
Their body is yellow, with glowing blue circles on it.

This is nature's way of warning everyone to stay back because they are very poisonous, and deadly to humans!
If they bite a person, they have a type of neurotoxin poison that attacks the nerves in the body and make it so they can't move any muscles.

Hawaiian Bobtail Squid


We just learned about the Coconut Octopus.

Another type of cephalopod is the Hawaiian Bobtail Squid.

This squid has a special type of bacteria that lives in its body that helps it glow a little, and also helps it change colors to match other things around it.

When it wants to hide, it buries its whole body under the sand, leaving just its eyes uncovered.

Coconut Octopus


We just learned about the European Squid.

Another type of cephalopod is the Coconut Octopus, also known as the veined octopus or amphioctopus marginatus.

This type of octopus lives mostly on the bottom of the water, and walks along in the sand.
It gets the name of coconut octopus, because it has been seen carrying empty coconut shells while it walks, and then when it wants to hide it climbs into the shell and closes it up.
Sometimes it will carry shells instead of coconuts and hide out in them, either hiding from predators or hiding so they can attack their prey.

Scientists also think that when it walks it looks like a coconut shell bouncing along the ocean floor.

European Squid


We just learned about the Cuttlefish.

Another type of cephalopod is the European Squid.

Squids are a lot like the cuttlefish, as they have eight short arms used for swimming and two tentacles used for grabbing their prey.
They also have a bone inside their body, kind of like the cuttlebone, but it is called the gladius.

They have a large part of their head called a mantle, with fins on the side.
Above the mantle is a tail.
Below the mantle they have the funnel where they breathe, and their eye.
At the bottom is their arms, tentacles and mouth.

Cuttlefish


We just learned about the Chambered Nautilus.

Another type of cephalopod is the Cuttlefish.

Cuttlefish have eight arms like an octopus, but they also have two tentacles that have sharp edges like teeth they use to hook onto their prey, or sting with venom.

They have very different eyes that are in a W shape, that lets them see in front and behind at the same time.
Cuttlefish have green and blue blood instead of red, and they have three hearts!

There is a bone in the middle of the cuttlefish's body called the cuttlebone that is made of aragonite.
This is like a hollow crystaline type of bone that they use to push air or liquid into, so they can float or sink.
Just like some other cephalopods, cuttlefish have ink they can squirt out when they are scared.
This ink was so dark that it was used for painting or in food, and the science name of Cuttle fish is "Sepiida" which is where we get the color name "sepia" from.

Cuttlefish are also sometimes called chameleons of the sea, because they can change their color to look darker, lighter or even change color to disguise themselves.

Chambered Nautilus


We just learned about the Common Octopus.

Another type of cephalopod is the Chambered Nautilus.

These cephalopods look sort of like snails, and they live in shells like a snail.
Inside their shells are chambers in a spiral shape where their body parts are squished into.

The top of their outside shell is dark on top and light on the bottom.
This helps them hide from predators, because looking down from above they blend in with the dark sea, and looking up from below they blend in with the sky above.

The nautilus grows from an egg, but they don't grow as a larvae like a lot of other cephalopods. They grow right from the start with a tiny shell, and the shell grows with them inside the egg until they hatch, about 1 inch long.

It is a meat eater, and it eats shellfish, but also eats garbage food floating around in the water or on the bottom of the sea.

They float up and down by changing how much water is in their shell.
If they want to go down, they suck in more water, and if they want to go up they spit some out.
You can think of it like a boat, that fills up with water and sinks, or empties the water and floats.
