An aquatic animal that fits this description is a crayfish. Crayfish are freshwater crustaceans with many legs and are typically found in rivers, lakes, and streams.
walking legs on a crayfish are used for mobility and movement, while the claws remain free to forage for food. This allows the crayfish to eat on the move and travel fair distances in a short time.
A swimmeret is many legs on the ventral side of a crayfish used for skilled swimming. The male uses it to carry eggs to the female crayfish.
