Having a hard shell, Lobsters live on the ocean floor.
There are many different types of lobsters, including
the Maine (or American) lobster which is a violent
lobster with large front claws, the spiny lobster, and
crayfish. Lobsters are invertebrates, animals without a
spine. Lobsters are cold-blooded; their body temperature
is function of the water temperature.

Most lobsters are nocturnal. It means that they are
mostly active at night. Lobsters are carnivores. They
are predators of
crabs,
clams, worms,
snails, mussels,

Life Cycle:
The lobster begins its life as a tiny, floating
organism, which is a component of
plankton. After
growing in a month, it sinks to the sea floor. It will
spend most of its time hiding from predators. As a
lobster grows, it often loses its old shell and grows a
new one.
Lobsters continue to grow all through their lives. The
biggest lobster weighs over 44 pounds (20 kg). Lobsters
may live up to 100 years old.
Predators:
Many animals eat lobsters, including
fish,
octopi, other lobsters, and
human beings.
