Surfperch

The surfperches are a family, Embiotocidae, of perciform fishes. They are found in coastal waters of the northern Pacific and grow up to 45 cm (17.7 inches) long.

They are viviparous fishes, in which the embryo is nourished directly by the mother as well as the yolk. This gives the family its scientific name, from Greek embios meaning "persistent" and tokos meaning "birth".
