From the Red Sea

摘要

S. pickeringae Lamprell, 1998. This Spondylus is quite variable and typically varies from forms with numerous dense short spines to forms with massive long spines. The rarest form is the albino shell. The two specimens shown here are from the north part of the Gulf of Aqaba, from 40-45 meters deep. The usual color form for the S. pickeringae is white ribs ending with large white spines. Between the major ribs are tiny brown spines giving the upper and lower valves their recognizable appearance. In the albino form these tiny spines are white. Both specimens are otherwise typical for this species. They measure 120mm for top image and 130mm for the bottom image.
