Tag: Tassled Scorpionfish (Scorpaenopsis Oxycephala)

Intro

Scorpaenopsis oxycephala, the tasseled scorpionfish, or small-scaled scorpionfish, is a species of venomous marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. It has a wide distribution in the Indian and Pacific Oceans. It is the largest species in its genus.

Taxonomy

Scorpaenopsis oxycephala was first formally described as Scorpaena oxycephalus in 1849 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker with the type locality given as Jakarta on Java. The specific name is a compound of oxy which means “sharp” and cephalus meaning “head”, an allusion to the long snout of this fish.

Description

Scorpaenopsis oxycephala has an elongate body which becomes compressed towards the rear with a narrow ontraorbital space. The upper posttemporal and upper opercular spines are simple. The occipital pit is either absent or very shallow. It has a very long snout and in adults there are numerous tentacles which form a beard around the mouth. There are 12 spines and 9 soft rays in the dorsal fin and 3 spines and 5 soft rays in the anal fin. The supraocular and postocular spines are widely merged in adults so that only the tip of the supraocular spine shows, and these flare outwards to create a ridge over the rear half of the eye. This species attains a maximum published total length of 36 cm , the largest species in the genus Scorpaenopsis. This scorpionfish has mottled and variable patterning of reddish-brown marked with white patches, and frequently with a darker triangular area underneath the eye that extends back over the cheek.
