Nootka Sound, BC, subtidal
Haliotis kamtschatkana Jonas, 1845
Pinto or Northern Abalone
very low intertidal to 35m northern Mexico to southern Alaska; Japan; Siberia size to 18cm
This is an endangered species in Washington where it has been severely overharvested and is still illegally poached. It is now rarely seen except by divers. The color can range from orange
to red to green which reflects what it has been eating. It has a pronounced spire and an irregular,
wavy/knobby sculpture. It is the most northerly occurring abalone. The southern species, Haliotis assimilis, the Threaded Abalone, was found to be genetically identical. The sculpture on the assimilis form is dominated by low ribs and occurs in the
southern part of the range - northern Mexico to southern California.
(Our specimens were collected many decades ago when harvesting was still allowed.)
