Description
The spotback wormfish is a small, worm-shaped fish of the wormfish family (Microdesmidae) from the eastern Pacific. The species grows to about 9 cm and has a very elongate, snake-like body with small eyes, a long low dorsal fin and a row of dark spots along the back, to which the name refers. It inhabits mud and sand bottoms near the shore, where it stays largely hidden in self-dug burrows. As a small bottom dweller it feeds on small zooplankton and small invertebrates. Owing to its hidden habits it is little seen; it is assessed as Data Deficient (DD). Owing to its small size it is harmless to humans.
