Diving with Anemone Shrimp

Koh Lanta Marine Life | Hippolytidae
Hinge-beak ShrimpStenopods

The Anemone Shrimp, also known as Cleaner Shrimp, Hump-back Shrimp, or Broken-back Shrimp, are a large family of over 330 species, including several species of cleaner shrimp. A small number of these species can be found during Koh Lanta diving.

Anemone Shrimp feed on algae and plankton, and are often spotted in small colonies blending in with their hosts. They can be found on algae, anemones, soft corals, sea whips and hard corals.

Some species of Hippolytidae can grow up to 8cm and are found world-wide, in both shallow marine and fresh water habitats.

They have 10 pairs of legs, with the front two pairs having pincers used for cleaning. The first (primary) pair of pincers are much larger than the second )secondary) pair of pincers.

The Marbled Shrimp has a dumpy body and distinct colouration. The rostrum (beak) is slightly longer than the main body, and the body colours vary widely, with a mostly brownish to reddish under colour, decorated with pinkish to bluish to whitish bands, spots and other mottled markings.

Colouration and patterns can be quickly changed for camouflage, though the colouration is generally ‘marbled’. The legs are generally always dark and white banded.

The dorsal area and abdomen or Marbled Shrimp have many tufts of hair-like bristles (setae), which are more dense in females. Females also have thick brush-like tufts of bristles on the first pair of legs.

The Marbled Shrimp is often found hiding in corals and around coral rubble and is capable of moving very quickly when necessary.
