Lepidotrigla Explained

Lepidotrigla is a genus of marine ray-finned fishes belonging to the family Triglidae, the gurnards and sea robins. These gurnards are found in the Eastern Atlantic, Indian and Western Pacific Oceans.

Taxonomy

Lepidotrigla was first described as a genus in 1860 by the German-born British herpetologist and ichthyologist Albert Günther with Trigla aspera, which had been described in 1829 from the Mediterranean Sea by Georges Cuvier, as the type species. The genus is classified within the subfamily Triglinae, the nominate subfamily of the family Triglidae. The genus name prefixes Trigla, the type genus of the Triglidae. with lepido, "scaled", a reference to the larger scales on these gurnards in comparison to those on Trigla.[1]

Species

Lepidotrigla is the most speciose genus in the Triglidae[2] and has 58 species classified within it:

Characteristics

Lepidotrigla gurnards are characterised by having the 3 lower rays of the pectoral fin free of the fin membrane and a scaled tail, like the other Triglid gurnards. The bucklers, bony plate at the base of the dorsal fin spines and rays, have with sharp spines on their rears along the whole length of both first and seconddorsal fins.[3] The groobe behind the eyes of these fishes may be complete, running from one side of the head to the other, or there may be just a furrow behind each eye. There are large, ctenoid scales on the body, although some species have cycloid scales on the belly. There are fewer tha than 70 scales in the lateral line. There may, or may not be vomerine teeth.[4] These relatively small grnards vary in size from the smallest, the spotwing gurnard (L. spiloptera) with a maximum published total length of, to the scalebreast gurnard (L. cadmani) and L. microptera, both having maximum published total length of .

Distribution

Lepidotrigla gurnards are found in the tropical and warm temperate waters of the eastern Atlantic, Indian and Western Pacific Oceans, with one species L. jimjoebob being found as far east as the Line Islands in the eastern central Pacific.
