The genus of this species has transitioned back and forth between Asterina and Patiria since its inclusion in Fisher's 1911 North Pacific Asteroidea monograph. [5] However, recent revisions based on molecular systematics have constrained Asterina and identified Patiria as a complex of three closely related species in the Pacific, including P. miniata, P. pectinifera in Asia and P. chilensis in ...
The Pacific/Chocó region is one of the five major natural regions of Colombia. Ecologically, this region belongs entirely to the Chocó Biogeographic Region and is considered a biodiversity hotspot. It also has areas with the highest rainfall in the world, with areas near Quibdo, Chocó reaching up to 13,000 mm (510 in) annually. [1]
