Limited morphological differences between genetically identified cryptic species within the Leptasterias species complex (Echinodermata: Asteroidea)
Sea stars of the Leptasterias species complex are common members of the rocky intertidal community of the temperate and subarctic North American Pacific coast. Variation in 53 morphological characters was studied in 645 Leptasterias spp. collected at 13 intertidal locations from the Aleutian Islands...

Sea stars of the Leptasterias species complex are common members of the rocky intertidal community of the temperate and subarctic North American Pacific coast.
