and lobster-like crustaceans
seen? Among our favourite seafood, lobsters do exist on our shores but they
are usually found in deeper waters and only sometimes seen by divers.
During the day, they are usually well hidden among corals. Those seen
on the intertidal, were sadly trapped in drift nets. Some relatives
such as mud lobsters and ghost shrimps are also common though rarely
What are lobsters? Lobsters and their relatives are crustaceans that belong to various Infraorders in the larger Order Decapoda.
The Family Palinuridae include some of the lobsters that we eat. There
are other lobster-like animals that are not really shrimps. Those
more commonly found on our shores include the mud
lobsters and ghost shrimps and mud
Features: Like shrimps, lobsters
and lobster-like crustaceans have a long body and broad tail, and long
antennae. Lobsters have heavy shells, unlike the light flexible exoskeletons
of shrimps. Lobsters and lobster-like crustacea have heavier legs
and tend to have powerful claws. They don't have swimmeretes (pleopods)
like shrimps do. But they can also rapidly move backwards by flexing
the abdomen and broad tail.
Human uses: Larger lobsters are
harvested as seafood everywhere.
