Presentation Transcript

  1. Lobsters

  2. Habitat Lobsters live in salty waters and in rocky shores.

  3. Locomotion. They walk on the ocean floor and they can also swim backwards

  4. Food The lobster feeds on the creatures on the ocean floor: starfish, worms, molluscs, fish and smaller crustaceans.

  5. Casing The lobsters have a casing that protects their soft bodies. When they get bigger they leave their old casing in order to grow a bigger one.

  6. Enemies Many animals eat lobsters: fish, octopi, other lobsters and people.

  7. Physical Description Lobsters are crustaceans. Crustaceans are a group of animals whose skeleton is on the outside of their body. There are many types of crustaceans, crabs, shrimps and lobsters are some of them. Lobsters have five pairs of legs, four of them are used to walk and the other pair, at the front, ends in large, strong pincers. With those pincers the lobster can break the hard shell of a crab. Lobsters are blue when they are alive .They breathe through gills, just like a fish.

  8. Reproduction Lobsters are born from eggs, the baby lobster is called larva. When the larva hatches from the egg, it floats freely with the plankton. Soon the larva moves to the bottom, where it develops its casing.

  9. Interesting Facts If one of their limbs gets trapped, lobsters have a special muscle to break off the limb so they can escape. Lobsters are called “fierce cannibals” because they will attack other lobsters, specially if their body is soft while a new casing is growing. One of the most interesting things about lobsters is that they may live 100 years.
