Leatherback Sea Turtle (Dermochelys coriacea) eating jellyfish, Atlantic Ocean off Lewes, Delaware, U.S.A
Today while following a plankton slick in 1-2 foot chop we came across a large leatherback sea turtle. I noticed it from approximately 50 m away as a large black, round object with a slight taper pointing up. As we approached it raised and lowered into the water as if taking breaths. The anterior, dorsal part of the shell was awash and the ridges that run along the dorsal side of the shell were visible. The specimen was large with a plastron approximately 5 feet or more in length. As we approached to within approx. 20 m the turtle started to sound. We got some clear views as it was completely submerged and Scott Bennett got some photos. My phone camera was completely unhelpful and I failed to get any decent video.

Guatemala was once a popular nesting site for the Pacific Leatherback sea turtles, but their populations have been documented to have declined by 99% just in the last 25 years due to extensive egg poaching across the entire central american coast, and further decimated due to by-catch caused by the Pacific long-line fishing fleets. Now La Barrona beach still is home to the species but on average 1 or 2 nests every 1 or 2 years.
Just hatched, heading for the water. More pictures on iNaturalist.
