Tretocidaris bartletti (A. Agassiz), Deep Sea Urchins

AvatarBy Barry Brown 5 years agoNo Comments


Hi friends, I have a large,rare sea urchin called a Tretocidaris bartletti (A. Agassiz) for you all today that was found this year by the Smithsonian scientists on the little island of Klein Curacao. This urchin was crazy colorful and huge; it was so big that it didn’t fit into a big white utility bucket – I ended up carrying it by hand back down to the reef where I took these photos of it walking around in the sand. These urchins range from North Carolina through the Caribbean, and live in depths of 140-625 meters (that’s 459-2050 feet) – that’s quite a range!  MORE
