Adaptations to sea life

Sea turtles are very well adapted to sea life. Some of their morphological features are:

  • Stream-lined body and short neck to reduce friction in water and to faciliate swimming.
  • Limbs being modified into flippers and the elongated front flippers help to give strong propulsion in water for agile swimming.

Sea turtles also have anatomical and physiological adaptation to sea life. For example, they have modified tear glands to get rid of excess salts in the form of brine twice as salty as seawater. They have a specialized respiratory system for prolonged diving.
