The Salt Excretion Process

Sea turtles live in salty oceans. They drink seawater to stay hydrated. But how do they get rid of excess salt? This process is fascinating and unique to sea turtles. Let’s explore the salt excretion process.

Mechanism Of Action

Sea turtles have special glands called lachrymal glands. These glands are located near their eyes. The glands filter out the salt from the seawater they consume. The excess salt mixes with tears. Sea turtles then excrete the salty tears from their eyes.

This mechanism ensures the turtles stay hydrated. It also prevents salt from building up in their bodies. The lachrymal glands work continuously. This helps sea turtles survive in the ocean.

Energy Consumption And Efficiency

The salt excretion process requires energy. Sea turtles use a part of their food energy for this. The process is highly efficient. It ensures minimal energy loss.

Sea turtles have evolved to optimize this process. They can balance their energy needs and salt excretion. This balance is crucial for their survival.

Despite the energy cost, the process is vital. It allows sea turtles to thrive in salty environments.
