Banded Coral Shrimp

(Stenopus hispidus)

Facts about this animal

The Banded Coral Shrimp is up to 7-10 cm long, the male being smaller and more slender. The female can also be recognized by the presence of greenish ovaries visible through the transparent carapace. The body colour is pink with white and red bands across the body and first legs. At the head there are four, white antennae of which two are forked. The antennae are twice as long as the body. The body surface is covered with short spines, which are used in defence. The first three pairs of legs have forceps, the third pair being significantly larger but the others are mainly used for cleaning fishes.

The Banded Coral Shrimp is a non-obligate cleaner shrimp of larger fishes and therefore waits - upside down - for customers swimming by. To signal is willing to clean it performs a dance shaking its white antennae and banded body. It may also feed on small fishes, other crustaceans, snails and worms. Sometimes food is sheared among mated partners. It rests by day and becomes active at dusk. Strong flips of its tail will help the Banded Coral Shrimp to escape in case of danger although no natural predatory enemies are known.

The species lives in monogamy and occupies territories of 1-2 m in diameter. Other crustaceans are not accepted within the territory. During mating the male will first display a courtship dance in front of the female. The male then transfers a sperm sack to the freshly moulted female which soon will inseminate the eggs and stick them to the abdominal legs. The young hatch after 16 days. Hatchlings will be attached to their mother for about six weeks before becoming part of the plankton. After some weeks and several moults the young settle down. The Banded Coral Shrimp may live 2-3 years, sometimes longer.

Lost limbs are regenerated quite easily during the next mould.
