Macrozoarces Gill, 1863 Zoarces is a genus of marine ray-finned fishes belonging to the family Zoarcidae, the eelpouts.

Blennius viviparus, which had been described in 1758 by Linnaeus in the tenth edition of his Systema Naturae from "European seas".

[5] Zoarces means "viviparous", i.e. giving birth to live young, however these fishes are ovoviviparous.

There are sharp, stiff spines at the rear of the dorsal fin, although infrequently this is absent in one species.

[7] Zoarces eelpouts are found in the northern Pacific Ocean and northern Atlantic Ocean, They are found from the sublittoral zone and continental shelf down to depths of 300 m (980 ft),[5] some even enter brackish water when spawning in the winter.
