This is an annual species; the adults spawn in January through March, and then nearly all of them die and are replaced by the larvae of the next generation by the following June. The diet of juveniles and adults is largely made up of amphipods. The larvae are prey for other fish such as the sunrise (Pseudoblennius percoides), a species of sculpin.
