How prawn swim move in water?

Prawns swim by using their swimmerets. Swimmerets are small, paddle-like appendages located on the underside of the prawn's abdomen. They are primarily designed to help the prawn balance, as well as move around the water, capture food, and clean its body.

When the prawn intends to swim, it begins by attaching itself to a substrate using its walking legs. This provides a stable base and helps it maintain its balance as it starts its swimming movements.

Once attached, the prawn starts beating its swimmerets rapidly and in a coordinated manner. Each swimmerets consists of a series of jointed segments, allowing for flexibility, as well as small, hair-like structures known as setae, which increase drag.

The rapid beating movements of the swimmerets generate thrust, propelling the prawn forward through the water. As the swimmerets move, the setae create resistance against the water, providing lift and helping the prawn to stay afloat.

Additionally, the swimmerets also aid the prawn in changing its direction while swimming, as well as performing quick bursts of speed if needed.

By skillfully maneuvering their swimmerets, prawns are able to swim efficiently and navigate their aquatic environment with precision and agility. Their ability to swim plays a crucial role in their survival, allowing them to capture prey, evade predators, and move freely within their habitats.
