Introduction I chose this topic because I like to make power point presentations about animals that I don’t see every day. You might be wondering what I mean by animals I don’t see every day, well I mean animals like: polar bears, seals, penguins, parrots, lions etc. But I am even more interested in sea creatures, like: sting rays, star fish, clown fish, squids, octopuses, jelly fish etc. And as you can see, I have chosen Octopuses !!! Now let me tell you about our eight legged friend the Octopus ! Have fun!

What Are octopuses? Octopuses are sea animals that are famous for their big bulging eyes, rounded bodies and eight arms / legs. If they loose an arm, a new one grows back ! They are amazing.

Where do they live? Octopuses live in these parts of the world : Even though octopuses are often considered to be “ The Monsters Of The Deep ” just like their cousins the Squids, they also live in shallow water. Most octopuses live along the ocean floor, but some species are pelagic, which means that they live near the water ’ s surface. Other species live in the deep, dark water. They rise from below at dawn and dusk to search for prey.

Octopuses are solitary creatures. They live in dens made out of rocks. Sometimes they even have a door ( a rock ) that they pull close when they are safely inside. Octopus in its den

Prey and predator Most octopuses eat crabs, shrimps and lobsters. But some catch and eat larger prey, like sharks. Octopuses drop down on their prey from above and using their powerful suction cups that line their arms pull the prey into their mouth. Octopuses can blast water through a muscular tube called a siphon to quickly get away. Seals, whales and large fish mostly prey on Octopuses. If octopuses are threatened, they shoot an inky fluid that makes the water dark, and which confuses the predator. Octopuses can change shape and colour. They can change to brown, pink, grey, green and blue to camouflage. They also change colour to communicate to other octopuses. siphon

Football Prediction Did you know that in 2010 for the world cups, an octopus named Paul was predicting the football matches? Someone would keep the 2 flags of the countries competing against each other on either side of its tank. Then the octopus would go to a flag and eat the food next to it, and that country would win ! Paul predicted 11 out of 13 matches right. He was kept in an aquarium in Germany. Paul was a male octopus, and his species was Octopus vulgaris. He died in October Most octopuses of his species only had a life - span of about 2 and a half years, so his death wasn ’ t unexpected. Some people think that Paul was really predicting, But some believe that he just went somewhere for food. Paul

Quick Facts The largest octopus is the North Pacific giant octopus. The scientific name for it is Enteroctopus Dofleini. It weighs up to 68 kilograms (150 pounds ) and measures 6 metres (20 feet ) from the tip of an opposite arm to another opposite arm. A female octopus lays thousands of eggs that are transparent under rocks or holes. She guards the eggs for about 4-8 weeks. After hatching, the young drift on the ocean ’ s surface for many weeks where most are eaten by fish or other animals. Octopuses that live in the bottom of the ocean who survive in this period descend to the deep, dark places.

To round up everything we ’ ve learnt, I ’ m going to show you a video. ENJOY ! kids/animals-pets-kids/wild-detectives- kids/wd-ep1-octopus/
