Leatherback Sea Turtle

Leatherback Sea Turtle

Dermochelys coriacea

Size: to 70" and 1200 lbs.

Habitat: oceanic

Notes: The largest sea turtle in the world, and also the most likely to be seen in our cold waters, since Leatherbacks are at least partially warm-blooded! As implied by the name, they have a leathery flexible covering, rather than the bony hard shell of all other sea turtles - a unique feature that has caused them to be placed in a family of their own, apart from all other sea turtles. Leatherbacks feed on jellyfish.

This one appears to have a propeller wound on its side.
It looks like it has been dead for a while.

PCBs

Poly-chlorinated biphenols (PCBs) and heavy metals ( Pb, Cu, Ni, Cd, Zn, Ag, and Hg ) have become an issue of concern with artificial reef development, as popular reef building materials ( e.g., ex-Navy vessels ) may contain quantities of these toxic materials that may potentially be transferred through the food chain. This transference, or bioaccumulation, may have unforseen effects on the marine environment and, ultimately, human health through consumption of contaminated finfish and shellfish harvested from these reefs. However, thousands of ships have met their demise without the environmental cleansing and preparation that artificial reefs require, perhaps posing a potentially greater health risk to consumers and divers.
