Description

The pinhead pearlfish is a remarkable pearlfish from the Indo-West Pacific. The species grows to about 30 cm and has a slender, rearward-tapering, partly translucent body without pelvic fins. Remarkably, it lives as a lodger inside the body cavity of sea cucumbers: it slips in through the anus and uses the sea cucumber as shelter, sometimes at its host's expense. It feeds on small zooplankton and tissue particles. The fish is harmless to humans. The IUCN has not evaluated the species.
