Where do the turtles go?
Every summer, thousands of endangered green sea turtles climb onto beaches around the world. Each mother sea turtle produces 100 or more eggs in a hole, and covers the hole with sand before she swims away.
Two months later, the eggs hatch(孵化), and the baby turtles climb out of the sand and swim into the ocean. They don’t reappear until they have grown as large as dinner plates. Until now, no one knows where the baby turtles go or what they do.
“if we don’t know where these little turtles are, we can’t protect them,” says Kim Reich, who helps solve part of the mystery.
Her teacher, Karen Bjorndal, has studied green sea turtles for more than 30 years. Every year, Bjorndal goes to the Bahamas Islands. Many young sea turtles come here to live and eat at the end of their childhood.
These turtles are the only sea turtles that live as plant eaters. In fact, their name may be a result of what they eat. The turtles don’t look green but they do have green fat. Scientists learned that the turtles eat green sea plants, which may turn their fat green.
Between 2002 and 2004, Bjorndal caught 44 green sea turtles in the Bahamas. After testing them, she found something to support the 20-year-old idea: baby green sea turtles eat meat before they turn to a diet of plants. In fact, they eat animals that live in the open ocean.
Scientists still need to find where exactly green sea turtles grow. We now know that baby green sea turtles are out in the open ocean, but the open ocean is a big place.
“It is really a problem,” says Bjorndal. The discovery may help us do a better job of protecting this sea animal.
