Abstract

Spndylus calcifer is the largest species of the family Spondylidae in America. It is distributed from the Gulf of California, Mexico to Ecuador. The fishery areas in Mexico occur along in the east cost of Baja California Sur. A typical species of the genus is characterized by a large muscle attachment behind the center of th shell. Because of its ecological and economical importance, a study was conducted on the basic biology and ecology of this species. Individuals sampled has heights between 40 and 170mm. Spondylus calcifer differs from S. princeps and S. leucacanthus in the color and size of the kidney. This Characteristic can be used to identify S. calcifer from the other species. The soft body weights 122g, and the adductor muscle can be 55% of the weight of the soft body. The reproductive season is in summer. The gonad can be 8% of the weight of the soft body. The ripe oocytes are 55- µm diameter.
