At most speeds, surfperches swim by beating their pectoral fins, not their tail as many other fishes do. For more information about pectoral fin swimming in surfperches, see the species pages for Cymatogaster aggregata and Embiotoca lateralis under Morphology.
A well-supported hypothesis describing the evolutionary relationships between surfperch species has been proposed by Bernardi and Bucciarelli (1999).

The surfperches are a family of perciform fishes, Embiotocidae. They are mainly found in northeast Pacific Ocean (as far south as Baja California), but a few species (genera Ditrema and Neoditrema) are found in the northwest Pacific, and the tule perch is found in freshwater habitats in California, USA. The largest species in the family reaches 47 cm (19 in).
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".
