Ophidiinae is a subfamily of marine fish from the male bearded family(Ophidiidae). It occurs worldwide in tropical and subtropical oceans.

features

The Ophidiinae reach body lengths of 7 cm to 2 m depending on the species. They have elongated bodies that are covered with round scales that overlap and are arranged in regular rows, or scales embedded in the skin that are arranged like wattle (anguilloid). Barbels are absent, the nasal region of some species from the genus Lepophidium is frayed, subnasal skin flaps have Ophidion lagocheila and the Parophidion species. The pelvic fins are supported by two fin rays of unequal length, the caudal fin by 9 (4 + 5). The sideline is incomplete and does not reach the caudal fin. The number of Branchiostegal rays is 7.

Way of life

Species from the Ophidiinae are found in all oceans. They live on the seabed on the shelf and continental slopes . Pre-juvenile stages of Cherublemma and perhaps Chilara are mesopelagic .

Internal system

The subfamily includes almost 60 species, which are assigned to eight genera and two tribes.

Tribe Lepophidiini

Genypterus blacodes

Lepophidium brevibarbe

Lepophidium jeannae

Lepophidium marmoratum

Lepophidium profundorum

Lepophidium staurophor

With the tribe Lepophidiini the trunk is covered with overlapping scales arranged in regular rows, the back of the head is completely scaled. In both sexes, the swim bladder is a simple sac without an anterior extension or opening and without associated modifications of the vertebrae (exceptions in some Lepophidium species, especially L. brevibarbe and L. prorates ). Pyloric tubes are available.

Tribus Ophidiini

In the Ophidiini tribe, the trunk is predominantly covered with wickerwork, non-overlapping elongated scales, the head is completely or almost without scales (except for Raneya ). The sides of the head, the gill cover and the lower head area are always completely free of scales. The swim bladder is stiff and short, in males it is often elongated in a tubular shape or provided with an opening. The posterior vertebrae have modifications to support the swim bladder. In males, the back part of the swim bladder can be enclosed in a bony capsule ("rocker bone"). Pyloric tubes are missing.
