Sweet Hitchhiker

Sweet Hitchhiker

March 18, 2019

This sea urchin was collected from the ocean floor near the Galapagos Rift. The hitchhiking urchin was found in the basket on the front of the Alvin submersible only after all the other samples had been removed. It is very small: this microscope photo belies the size of a body that is only about 1 centimeter in diameter. (Photo by courtesy of Woods Hole Oceanographic Institution Archives)
