KARYOTYPE STUDY IN THE SURF CLAM MESODESMA DONACIUM LAMARCK, 1818 (BIVALVIA: VENEROIDA: MESODESMATIDAE)

Mesodesma donacium is a marine clam distributed from Sechura Bay (5°S) in northern Perú to Chiloé Island (43ºS) in southern Chile. Due to the commercial importance of this species, their populations have been reduced in the later years. In this work the karyotype morphology of M. donacium is describ...
