† Populations may not be currently present.
Ecology: Occurs on sandy or muddy bottom habitats; often enters estuaries, bays, and sloughs. Primarily consumes polychaete worms and siphon tubes of bivalves.
Means of Introduction: Intentionally stocked.
Status: The introduction failed to produce a viable population and the species is extirpated in the Salton Sea.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
