Researchers discovered a new species of giant clam in the Red Sea.
They believe the Tridacna costata is evidence of some of the first over-harvesting by human beings. Fossil records indicate the species accounted for the overwhelming majority of clam life in the Red Sea until sometime between two of the Ice Ages. Researchers think this may have been when humans first started inhabiting the area.
The species is now believed to be endangered.
