Dykning med Anemone-rejer

Anemone-rejer, også kendt som Cleaner Shrimp, Hump-back Shrimp eller Broken-back Shrimp, er en stor familie med over 330 arter, herunder flere arter af cleaner shrimp. Et lille antal af disse arter kan findes under dykning på Koh Lanta.

Anemone-rejer lever af alger og plankton og ses ofte i små kolonier, der falder i ét med deres værter. Man kan finde dem på alger, anemoner, blødkoraller, søpiske og hårdkoraller.

Nogle arter af Hippolytidae kan blive op til 8 cm og findes over hele verden, både i lavvandede havområder og i ferskvand.

De har 10 par ben, hvor de to forreste par har en tang, der bruges til rengøring. Det første (primære) pincetpar er meget større end det andet (sekundære) pincetpar.

• Marbled Shrimp (Saron marmoratus)
• White-Banded Cleaner Shrimp (Lysmata amboinensis)

Marbled Shrimp

(Saron marmoratus)

Saron marmoratus @ Koh Haa

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.
