Benthic. Subtropical
Pacific Ocean: Alaska to Mexico. Boreal to tropical.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 5.4 cm SHL male/unsexed; (Ref. 95344); common length : 4.0 cm SHL male/unsexed; (Ref. 312)
Apex near center, irregular ribbed slopes. Some possess a brown colored shell with alternating brown and white checks at the edge. Other colorations of this limpet exist and can be found in the same area. Both the substrate the limpet lives and its diet determine the color of its shell (Ref. 312).
It has a shell length of 4 cm (Ref. 312). Maximum shell height at 1.5 cm (Ref. 95344). Occurs in the middle to high intertidal zone (Ref. 312); common from the low to mid-intertidal; the largest individuals are found lower on the shore farthest from effect of wave action (Ref. 310). Non-selective herbivores, consuming a wide variety of algae (Ref. 312). Commonly found in mussel beds and associated with brown algae (e.g., the sea palm, Postelsia)
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the order Patellogastropoda are mostly gonochoric and broadcast spawners. Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults.
