Special needs

Flat abalone occur only in rocky, shallow subtidal habitat. Their geographic range is limited to the area between northern California and Washington.

Limiting factors

Flat abalone require sufficient density for successful broadcast spawning. They produce short-term, yolk-dependent larvae, with infrequent recruitment.
