The Hemerocoetidae are a family of bottom-dwelling, small marine fish found in the Pacific and Indian Oceans .

features

The species of the Hemerocoetidae are elongated fish that are three to 28 cm long. Both jaws are usually the same length or the upper jaw is slightly longer than the lower jaw. The scales along the sideline are trilobed or sawed on the rear edge. Usually the fish have two dorsal fins, the first, very short, can also be missing. The spines of the dorsal fin are very close together at the base. The scales of the sideline are three-lobed or sawed. In some species of the genus Hemerocoetes , the males wear a barb on the tip of the snout.

• Fin formula: dorsal II – VI / 6, caudal 7–8.

Systematics

The Hemerocoetidae were described by the German zoologist Johann Jakob Kaup in 1873 and assigned to the Percophidae as a subfamily (Hemerocoetinae) . However, the Percophidae are not a monophylum , but are a group of bottom-dwelling fish that have developed convergent , but are not closely related to each other. The Bembropidae (ex Bembropinae) were raised to the rank of an independent family as early as 2013. In mid-2015, the goby expert Christine Thacker published a study on the relationship between the sand divers (Trichonotidae) and the gobies (Gobiidae), in which two taxa of the Percophidae were included, since in the past they were classified together with the sand divers in the paraphyletic trachinoids . Thacker and colleagues gave the Hemerocoetidae family status for the first time and established a close relationship with the sand cave fish (Creediidae) found in the same habitat , which are the sister group of the Hemerocoetidae and form the suborder Hemerocoetoidei with them. Other relatives are the glass or hatchet fish (Pempheridae), the pearlfish (Glaucosomatidae), the armored heads (Pentacerotidae), the banjo fish ( Banjos banjos ), the lantern bellies (Acropomatidae), the wreck bass (Polyprionidae), the Howellidae and the Ostracoberycidae . This monophyletic group, unnamed by Tacker and colleagues, forms the order of the Pempheriformes in the current revision of the bony fish system .
