Molecular evidence of the existence of two sibling species within the echinothurioid echinoid Asthenosoma ijimai from Japanese waters.

Zoological science - 1 Oct 2004

Matsuoka Norimasa, Kohyama Kuniko, Arakawa Emi, Amemiya Shonan

Abstract excerpt

The echinoid, Asthenosoma ijimai belonging to the order Echinothurioida from Japanese waters shows the geographical variation in morphological and ecological characters. The echinothurioid from Ryukyu Islands in southern Japan is cleary different from that of Sagami Bay and Suruga Bay in the middle part of Japan at non-molecular level. Their phylogenetic and taxonomic relationships were studied at the molecular...
