Pink Abalone

Haliotis corrugata

Order: 

Archaeogastropoda

Family: 

Haliotidae

Pink abalone (Haliotis corrugata) have rounded shells with corrugated edges (2). Their shells have two to four elevated shell holes (1). Exterior shells coloration is dull green to reddish brown with a pink interior with (1). The body and tentacles are black with black and white fringes (1). Lifespans of over 30 years allow H. corrugata to reach lengths of 25 cm (2)(4). They occupy sheltered intertidal waters, living and feeding within a homesite (3)(4). H. corrugata are herbivorous, feeding on kelp and drift algae, with juveniles active primarily nocturnally and adults active an equal amount between day and night (3). While pink abalone are the most common abalone species in southern California populations have seen steep decline since the 1940s (2)(4). This decline is attributed to overfishing and disease, withering syndrome (4).
