Rhinopias eschmeyeri is a Scorpionfish from the Indo-West Pacific. It grows to an average size of 16.6 cm in length. Common names in English are Eschmeyer's scorpionfish and Paddle-flap scorpionfish. It occasionally makes its way into the aquarium trade. Although some have raised questions as to whether R. eschmeyeri is a morphological variant of Rhinopias frondosa rather than a separate species, a 2006 study by Motomura and Johnson confirmed the species' existence and distinguished it from other members of the genus Rhinopias.

Description

Eschmeyer's scorpionfish has a maximum length of 23 cm (9 in) and its dorsal fin has twelve spines and eight to nine soft rays while the anal fin has three spines and five soft rays.

According to Motomura and Johnson, R. eschmeyeri "differs from R. aphanes and R. frondosa in having two tentacles on the underside of the lower jaw (vs. 12-18 tentacles in R. aphanes and 9-24 in R. frondosa), lacking tentacles on the frontal below the eyes in anterior view (vs. 2-4 tentacles present in the two species), lacking distinct tentacles on the lateral surface of the body above the lateral line (vs. present), having short tentacles, without distinct branches along distal margins, on the supraocular and posterior lacrimal spines (vs. long tentacles, with distinct branches) and having head, body, fins, and tentacles usually without distinct pigmentation or markings (vs. with elongate black-margined white markings each with a central region of yellow, green, or brown in R. aphanes and with numerous distinct circular dark-margined spots in R. frondosa)."

Distribution and habitat

R. eschmeyeri is native to the tropical western Indo-Pacific. Its range extends from the coasts of East Africa to Japan, Indonesia and the northern half of Australia. Its depth range is 18 to 55 m (59 to 180 ft) and it is usually found on coral reefs or rubble seabeds.
