Octopuses

Introduction

• A crab moves swiftly along the ocean floor. Suddenly a creature moves out of a cave. What is the animal? It is a octopus eating a crab.

Where they live?

• Octopuses live in oceans around the world. Some can live in the freezing cold places like Arctic and the Antarctic. Many small octopuses live in the coral reefs. Larger octopuses live in the freezing cold areas. Some like the blue-ringed octopuses live in shallow water! The very few types live in the deep seas that are nearly 36,000 feet! Octopuses live in oceans that are rocky or have coral, or live in cold blank seas.

• Octopuses mainly live in the Pacific ocean. Some shallow waters are home to very small octopuses, but are very warm. Octopuses usally live on the sea bottom. Octopuses can live on open water where there is barely no seafloor, but search for food that could swim.

• Octopuses live in aquariums in fish tanks with locked lids. They can squeeze themselves in tight spaces in aquarium tank corners. Deep sea octopuses live in seas that are over 5,280 feet from the surface.

What they look like

• Octopuses have a saclike body made out of a material called mantle. Their bodies have these tentacles with suckers on the edge of the tentacle. Suckers help a octopus taste food, hold food, and catch food. In the middle of all the rope like tentacles is the beak. The octopus has a siphon that shoots water and helps the octopus swim. Above the siphon is the eye. The octopus has very good eyesight.

• The mouth is around the beak . It`s spicky tongue has poisonous saliva can paralyzes a struggling prey and kills the animal. You may not be able to see a octopus mouth because the beak is taking up many space of the mouth. If you see that around the octopus tentacles is several small pieces of blubber. The largest octopus caught was 33 feet and weighed 600 pounds!

What are their predators

• Octopuses main predator is the great white shark. There are also fish eating predators. Great white sharks eat many octopuses than many other predators. Another predator is the Moray eel. These predators hide in caves and wait for a octopus to come close to it. The octopus knows when a Moray eel is hiding. They swim quickly away so they won`t get eaten for food. Deep sea octopuses have these gulper eels as a predator.

• They open their umbrella like jaws to swallow octopuses. The seal can feed on octopuses. But a octopus can jet proupolt by using the siphon. The human can eat tentacles of a octopus. They catch octopuses by a fishing nets. Octopus ink are used for plastic pens. Tiger sharks eat almost everything in the ocean they may eat octopuses. They have a huge rounded blunt nose.

• They eat octopuses from anywhere they can find one. Whales and dolphins eat these octopuses, too. They hunt for octopuses in schools. Orcas are a whale who eat octopuses. Orcas and dolphins hunt in small school, and can swim fast. Octopuses can protect themselves by jet propulsion ink blast and camouflage.

What they eat?

• Octopuses can eat fish, shellfish, and mollusks. Octopuses usually eat shellfish. Crabs, crayfish, lobsters, clams, mussels, and oysters. Clams are usually very easy to find because they don`t move. Crabs and lobsters scatter along around and pinch a octopus. Octopuses eat dead, or non-moving fish. They can eat fish in mid swim. Octopuses are very strong because of their net-like bodies are made out of strong blubber and sticky suckers.

• A animal such as young sharks can get trapped. Octopuses can eat dead sharks also. Octopuses only eat underwater mollusks such as clams, oysters, and scallops. These have hard shells and tasty meat for a octopus. They are a non-moving creatures, and are easy for a octopus to catch. Crabs lobsters and shrimp are hard to catch because they move and pinch. They can`t stay still until the octopus paralyzes them.

Different kinds of octopuses

• The Northern giant pacific is the biggest octopus in the world. It can grow up to at least 14 feet! The largest octopus caught could be a giant pacific octopus. A blue-ringed octopus is small but they are poisonous. The blue-ringed octopus can kill a human in only TWO MINUTES! The vampire octopus is has a black body, and has a red beak and eyes. These octopuses can also be called a vampire squid.

• Vampire octopuses have lights on their webbed blubber. If you touch the tip of their tentacle their lights glow up immediately. The vampire octopus lives in deep midnight zone. They are harmless to people. If a vampire octopus is threatened it pulls up its blubber like a normal vampire bat. It usually scares away predators. If the vampire octopus sees something delicious to eat it drops like a net to capture prey.

• If that sounds creepy keep in mind it is a little creature. The female blanket octopus is 6 feet long. A male blanket octopus is rare because it is under a inch long! The male hides in a jellyfish`s tentacles, and waves them in front of a predator. For example a 8/10th inch blanket octopus can wave a jellyfish`s tentacles in front of a predator`s face! A mimic octopus are harmless, but they can look like a poisonous animal.

The mimic octopus can look like a sea snake, a flatfish, and a lionfish. They can look like any deadly fish. The Yam octopus is a medium sized octopus. They have many things like a common octopus. The glass octopus is transparent, and their tentacles are as big as a dinner plate! They have a greenish beak, and has a eye that can be visible.

• The banded-string arm octopus has very loose tentacles. They have long and thin arms. Their arms are attached loosely to the body. The banded-string arm octopus is shaped like a spider. The common octopus has long tentacles. It has a sleek brownish body. They are a small octopus so they live in coral reef.

Babies

• An female octopus lays eggs in a cluster. Each egg is small. They are smaller than a pea. Not all of them survive to be a adult. Mom is probably lucky to be a adult. Mom doesn't stay alive. She dies after the baby octopuses -hatch. 7-15 or more can survive to be adults. The baby has a small unique size. There size is as big as a pea. They swim away after they hatch.
