Green sea turtles are the most common type of marine turtle in tropical and subtropical waters (How many countries do they nest in? It’s this week’s trivia question on Twitter, so answer now to win!)
Green sea turtles begin their lives on sandy beaches. Every year, females return to the beaches where they themselves were born to leave their eggs buried in the sand. After six or eight weeks, the hatchlings use their egg tooth, which later falls out, to break out of the shell. All of the eggs in a clutch hatch at the same time, and the hatchlings make their way together to the ocean.
This hatching process means that young green sea turtles are often eaten by predators like ghost crabs, gulls, sharks, and dolphins. Those that survive live in the deep ocean for a few years and then move to shallower waters along coastlines and reefs. Young green sea turtles eat animals like jellyfish, crabs, and snails, but adults, unlike most types of sea turtles, eat only plants.
Green sea turtles in Florida and the Pacific side of Mexico are considered endangered by the IUCN; the other global populations are classified as threatened. One of the biggest threats to green sea turtles is accidental capture in fishing gear, also known as bycatch. Oceana’s sea turtle campaign focuses on preventing sea turtle bycatch and protecting habitat.
You can learn more about green sea turtles -- and hundreds of other marine animals -- from Oceana’s marine wildlife encyclopedia.
Time for another FOTD!
Green sea turtles are born only two inches long and will grow to about three feet by adulthood. On average, young green sea turtles grow more than 11 pounds a year by feeding on sea grasses and algae -- yum!
Sea turtles can become coated in oil or inhale volatile chemicals when they surface to breathe, swallow oil or contaminated prey, and swim through oil or come in contact with it on nesting beaches.
As of yesterday, 32 oiled sea turtles have been found in the Gulf of Mexico and more than 320 sea turtles have been found dead or injured since the spill began April 20.
While some dead and injured sea turtles are found by search crews or wash up on the beach, some never will. Ocean currents often carry them out to sea where they can sink or be eaten by predators.
Our report shows that the ongoing oil spill can have the following impacts on sea turtles:
