Leatherback turtle (Dermochelys coriacea) — In September 1988, a leatherback turtle estimated to be 100 years old was found washed ashore in Gwynedd (UK). Length: 2.74 m (9 ft). Weight: 914 kg (2,015 lbs). Despite its colossal size, the leatherback feeds almost exclusively on jellyfish, including the world’s largest, the lion’s mane. A single leatherback may be able to eat the equivalent of its own bodyweight in jellyfish and other plankton every 3 days. Unfortunately, its diet of jellyfish further threatens the survival of this endangered species since it is prone to swallowing plastic bags and other drifting trash which it regularly encounters throughout its entire range. The leatherback is also the world’s deepest diving turtle.
