Ecsenius axelrodi

Ecsenius axelrodi, known commonly as the Axelrod's clown blenny or the Axelrod's combtooth blenny, [3] is a species of ray-finned fish in the family Blenniidae, the combtooth blennies. It is found in shallow water on coral reefs in the western central Pacific Ocean. It was first described by Victor Gruschka Springer in 1988 and named in honour of the American ichthyologist Herbert Richard Axelrod. [4]

Description

Axelrod's clown blenny

Ecsenius axelrodi is a small species growing to a maximum length of 5.8 cm (2.3 in). The dorsal fin has 12 spines and 12 to 14 soft rays. It is deeply notched between the two portions of fin. The anal fin has 2 spines and 14 to 16 soft rays. This combtooth blenny is variable in colour but usually has broad orange bands running along the body and transverse black bars on the rear half of the body. It occasionally has black longitudinal stripes. The eyes are prominent and have a black line running through them. This fish can be distinguished from other similar species by the obliquely-sloping, oblong black spot just above the insertion of the pectoral fin, and the four of five round black spots just below the spinous dorsal fin. [4] [3]

Distribution and habitat

Ecsenius axelrodi is native to the western central Pacific Ocean. Its range includes the Admiralty Islands, Papua New Guinea and the Solomon Islands. It occurs on coral reefs on outer reef crests and slopes at depths of down to 15 m (49 ft). [3] Both adults and juveniles are restricted to subtidal areas with live corals. [4]

Biology

The breeding habits and early life history of Ecsenius axelrodi has been little studied. The females are oviparous and there is a planktonic larval stage but the smallest identifiable juveniles found are over 10 mm (0.4 in) long and look like miniature adults. [4]

<span class="mw-page-title-main">Combtooth blenny</span> Family of fishes

Combtooth blennies are blenniiformids; percomorph marine fish of the family Blenniidae, part of the order Blenniiformes. They are the largest family of blennies with around 401 known species in 58 genera. Combtooth blennies are found in tropical and subtropical waters in the Atlantic, Pacific and Indian Oceans; some species are also found in brackish and even freshwater environments.

<span class="mw-page-title-main">Blenniiformes</span> Order of fishes

Blenny is a common name for many types of fish, including several families of percomorph marine, brackish, and some freshwater fish sharing similar morphology and behaviour. Six families are considered "true blennies", grouped under the order Blenniiformes; its members are referred to as blenniiformids. About 151 genera and nearly 900 species have been described within the order. The order was formerly classified as a suborder of the Perciformes but the 5th Edition of Fishes of the World divided the Perciformes into a number of new orders and the Blenniiformes were placed in the percomorph clade Ovalentaria alongside the such taxa as Cichliformes, Mugiliformes and Gobiesociformes.
