Squids and Octopus
Where do these bad boys live?
Squids and octopus have a very wide range of territory they live in. All types of squid and octopus must live in the ocean to survive. Some of the smaller types live closer to the surface, mostly along reefs. Most of the larger types of squid and octopus live deeper in the ocean, where there is more room for their large bodies. They must live in areas where there are lots of fish, as this is their main food source.

How are they important to us?
Squids and octopus play an important role in humans' lives. In the lives of fishermen, they are very important. They can be caught and sold for profit. They are also very useful as bait for larger fish. The giant squid also has a large role in many stories about sea monsters.

How do they feel stuff?
Squids and octopus have some very sensitive feelings. Their eyes are really good so they can look through the water for predators. They also have little taste-bud things in the tips of their tentacles so they can taste the water and see if the food they are about to eat is good or bad. Squids and octopus are also very smart. Their brains are really highly developed so they can form plans and stuff.

How do they poop and pee?
The system that these animals use to poop and pee is quite interesting. Any kind of solid waste, or poop, they make is passed through their anus. The squid's pee is called nitrogen waste. This is passed through the body by little organs called nephridia. Both squids and octopus have a little ink sac that they can shoot out for defense.

What are some unique features about squid and octopus?
Some cool things about squid and octopuses that they all have an ink sac to get away from their enemy. They also are flexible so that they can fit in difficult places. Their jelly-like bodies make them hard to catch. They are able to change color to protect themsleves. They don't have shells so that means that they have to find cover in other places from their enemy's. A sad thing is that every few years they commit a massive suicide. This means they kill themselves. They also have suckers to bring in their food and then rip it apart.

Do they have bones?
They don't have any bones to support their bodies. They have a hard beak to eat their food. If you were to pick one up, it would feel like a big slimy bugger in your hands. All kinds of squid have different ways of supporting their bodies. Remember that no octopus or squid have bones.

How do they mate?
They mate by the male fertilizing the female. The female then lays the eggs in a jelly like substance. The eggs are usually watched over by the female until they hatch. The average life span of a squid or octopus is about one to two years. Most squid stay small for most of their lives, but some grow up to be 15 to 20 feet long.

How do they digest their food?
Squid and octopus have a complex digestive system. First they take large chunks of food out of their prey. The food then gets passed to its stomach. As the food is getting digested the nutrients go to the caecum. After the nutrients have been used up the waste goes to its liver then exits the body.

How does their blood move?
A circulatory system is how the blood moves around through the body. The circulatory system of a squid or octopus is very detailed. Squids and octopus have three hearts. Two of the hearts pump blood through the gills. The other heart is used to push the blood through the rest of the body. They have a closed circulatory system, which is much like a human's circulatory system. Blood is pumped through the body using blood vessels, which look like tubes, only.

How do squids and octopus breathe?
The gas exchange is a mollusk's respiratory system, in other words, how they breathe. Gills are a very important part of the mollusk. In order to be able to swim fast they have to have small gills. The faster the animal is, the smaller the gills are. Squids and octopus breathe through gills that are located inside the body. They also switch gases through exposed, or open, wet skin.

Why are squids and octopus important to the environment?
Squids and octopus are very important to the environment. Like every other animal, the squid and octopus keep their predators full and their prey's population in check. Scientists do not think squids and octopus are endangered mainly because scientists have not been able to figure out a lot about them and their numbers. Cephalopods are food for the flightless cormorant – an endangered bird. Squids and octopus make it easier for the bird to stay alive.

Are there cool kinds?
There are 800 kinds of cephalopods. A cool one is Longfin Inshore Squid . This squid lives less than a year and has kids all year long. Another kind is the Common Octopus . You probably have seen this kind of octopus in all the pictures. This animal is smart. A Common Octopus can unscrew a lid on a jar! Another kind of cool cephalopod is a Pearly Nautilus . There are fossils of the Pearly Nautilus from 5000 years ago! The Giant Squid is huge. It can grow up to 43 feet long. One of the coolest ones is the Vampire Squid . The vampire squid is only 1 foot big, but it is lined with spikes on its back.

Open vs. Closed
In an open circulatory system, the blood is pumped through open spaces call sinuses. It does not work very well, but it is ok for the mollusks that do not move really move, like snails. A closed circulatory system is the system where blood is pumped through tubes, or vessels. The closed system is better used for animals that move more.
