Pederson Cleaner Shrimp

Ancylomenes pedersoni

Sighting evidence at Gasparee Island Caves, Trinidad

Pederson cleaner shrimp establish cleaning stations at the cave mouth and in shallow cavern sections, waving their antennae to attract passing fish. They remove parasites and dead tissue from fish clients including moray eels and grouper, providing a service that maintains reef fish health. Their abundance at Gasparee reflects the mix of open-reef fish visiting the caves and the protected substrate the caves offer.
