Description

The dwarf surfperch is a small fish of the surfperch family (Embiotocidae) from the eastern Pacific off the west coast of North America. The species grows to about 16 cm and has a silvery, oval body. It inhabits rocky inshore areas to about 9 metres, often among seaweeds. As an omnivore it feeds on algae and small invertebrates. Characteristic of surfperches is that they are livebearers: the female carries the young internally and gives birth to relatively large, immediately free-swimming young. The dwarf surfperch is harmless to humans.
