The pearl fish or pearlfish (Carapus acus) is a species of bony fish in the family Carapidae, the pearlfishes, and is native to the Mediterranean Sea and the Atlantic Ocean. It lives as a commensal in association with a sea cucumber, spending the day inside its host and emerging at night to feed. Carapus acus usually lives inside the respiratory tree or the body cavity of sea cucumbers. Neither the species nor the size of the host seem important in host choice, and the fish makes use of whatever sea cucumber it happens to encounter; the most common hosts are Parastichopus regalis and Holothuria tubulosa.
