SSC MTS EXAM

Detailed explanation-1: -Just like other reptiles, sea turtles have lungs. They have a slightly different structure than mammalian lungs, but work just as well when it comes to exchanging gases (oxygen and carbondioxide). The lungs are located right under the carapace and the vertebral column.

Detailed explanation-2: -Sea turtles are adapted to live in the ocean, with some unique features that help them to survive in the marine environment. As reptiles, they require air to breathe and land to lay their eggs. However, the majority of their lives are spent underwater.

Detailed explanation-3: -Chelonian sea turtles use their lung as a buoyancy organ and as the major oxygen store when diving, and hence, buoyancy regulation and oxygen consumption can be expected to interact.
