A Closer Look at the Leatherback
Leatherback sea turtles, also known as Dermochelys coriacea, are the largest of all sea turtles, and their appetites match their impressive size. They can weigh up to 2,000 lbs. and measure over 8 feet, "which, according to some researchers, makes it the world’s heaviest reptile." They are the only species of sea turtle that does not have a hard shell. They get their name from the texture of their shell, which feels like leather. Their soft shell is an adaptation that allows them to dive deeper than a submarine and can stay down for up to 85 minutes before coming up for air.
Quick Facts about Leatherback Sea Turtles:
Habitat: Leatherback Sea Turtles are found in the Deep Seas of the Atlantic, Pacific, and Indian Oceans. They occupy U.S. waters in the Northwest Atlantic, West Pacific, and East Pacific. Within the United States, the majority of nesting occurs in Florida, Puerto Rico, and the U.S. Virgin Islands. We are happy to say that they also swim in the Gulf of Mexico and have nested on the Northwest Panhandle beaches during our Nesting Season, May 1-October 31.
Reproduction: The Leatherback female will lay approximately 50-90 very large eggs that are about
the size of a tennis ball. Female leatherbacks nest every 2-4 years and lay 4-7 clutches of eggs per season, which means leatherbacks lay an average of 350 eggs in a nesting season! Their nest’s incubation period is approximately 70-80 days long. Unlike other sea turtles, Leatherback females may change nesting beaches, though they tend to stay in the same region
Diet: Their diet consists mainly of jellyfish. Leatherbacks dive deep in search of jellyfish, some of which are as big as a car! The Lion’s Mane is the largest jelly, also known as the giant jellyfish and can weigh up to 200 pounds. Leatherback sea turtles have quite an appetite for jellyfish! On average, they can consume about 73% of their body weight in jellyfish each day1. To put that into perspective, a 1,000-pound leatherback could eat approximately 730 pounds of jellyfish daily2. Leatherbacks don’t have to worry about being stung because they don’t have sensitive skin like we do. Another adaptation they have is specialized notches in their top jaw that allows them to catch jellies easier; there is no escaping a Leatherback's hooks.
Sea Turtles Ecosystem:
These magnificent creatures rely on these gelatinous delicacies to fuel their incredible journeys across the oceans. By feasting on jellyfish, leatherbacks not only satisfy their appetites but also help maintain the delicate balance of the marine ecosystem. So, the next time you spot a Leatherback Sea Turtle gracefully gliding through the waves, remember the importance of their unique diet and the role they play in our vast oceanic world.
