A genus of small marine fish in the family Centriscidae, characterized by a long tubular snout used for hunting small prey.
From modern Latin scientific nomenclature, possibly from Greek kentron 'spur' or 'center' combined with iskus relating to spine or structure. Used as the type genus for the Centriscidae family.
Centriscus fish are living examples of extreme specialization: they've evolved snouts so thin they can only eat tiny copepods and similar microscopic creatures, making them one of nature's pickiest eaters.
