Info

Elops affinis Regan, 1909

The Pacific ladyfish (Elops affinis), also known as Pacific ten-pounder and machete, is a species of ray-finned fish in the genus Elops, the only genus in the monotypic family Elopidae. The Pacific ladyfish is found throughout the US Southwest and other areas of the Pacific Ocean.

Elops affinis are pelagic marine forms that prefer either brackish or fresh water unless used for breeding season.

This species uses a wide range of water salinities to spawn. Under normal conditions, Elops affinis live in brackish water, but migrate deep into oceanic, salty waters to reproduce. They lay their spawn far from the shore in plankton-rich regions to provide them with nutrients as young animals. The larvae look like eels when they are born, but are distinguished by their forked tail. Their young mostly feed on crustaceans in brackish or coastal waters. This could explain their instinct to migrate from the Gulf of California to lower Colorado during floods.

They feed on smaller fish and crustaceans.
