Trachinidae (weeverfish; subclass Actinopterygii, order Perciformes) A small family of marine, bottom-dwelling fish that have an elongate body, a large, oblique mouth, and the eyes situated on top of the head. The short, spiny-rayed, dorsal fin is separated from the long-based, soft-rayed, dorsal fin by a distinct notch. All weeverfish possess poison glands at the base of the spiny dorsal rays as well as on the spine of the gill cover. These spines can inflict painful wounds. There are four species, distributed in the eastern Atlantic.
