Propulsion: Otters use their tails as the primary means of propulsion in water. They swing their tails from side to side, generating thrust and propelling themselves through the water. The broad and flat shape of their tails provides a large surface area, allowing them to push against the water effectively and generate significant speed.
Manoeuvrability: The tail acts as a rudder, enabling otters to control their direction and make quick turns while swimming. By swishing their tails in different directions, otters can navigate through narrow spaces and turn sharply to catch prey or avoid obstacles.
Balance and Stability: The tail provides balance and stability when otters are swimming or diving underwater. It acts as a counterweight to their movements, allowing them to maintain equilibrium and stay upright in the water.
Steering: Otters can adjust the position of their tails to steer and control their movements. By raising or lowering their tails, they can fine-tune their swimming direction and maintain their desired course in the water.
Overall, the otter's tail serves as a powerful tool for swimming, enabling these semi-aquatic mammals to excel in their natural environment and efficiently pursue aquatic prey.
