Some Arthropod groups can swim – including many crustaceans. Most crustaceans, such as shrimp, will usually swim by paddling with special swimming legs . Swimming crabs swim with modified walking legs . Daphnia, a crustacean, swims by beating its antennae instead. There are also a number of forms of swimming molluscs.
Scartelaos histophorus, commonly known as the walking goby, is a species of fish in the family Oxudercidae.This species is notable for its unique ability to "walk" on land, using its pectoral fins to propel itself forwards.
The latter group swim slowly, but can turn rapidly, as is needed when living in coral reefs for example. But they can not swim as fast as fish using their bodies and caudal fins.

Native to south-east Asia, this fish has strong spines on its pectoral fins that enable its body to "walk" across dry land. It travels from waterhole to waterhole, where it seeks refuge and makes ...
Evolutionary theory says all animals that are walking on land actually evolved from sea-dwelling creatures at some point in the ancient past. To study this further, scientists from McGill ...
Wading and bottom-feeding animals (e.g. moose and manatee) need to be heavier than water in order to keep contact with the floor or to stay submerged, surface-living animals (e.g. otters) need the opposite, and free-swimming animals living in open waters (e.g. dolphins) need to be neutrally buoyant in order to be able to swim up and down the ...
Pinnipeds can move around on land, though not as well as terrestrial animals. Otariids and walruses are capable of turning their hind-flippers forward and under the body so they can "walk" on all fours. [48] The fore-flippers move along a transverse plane, rather than the sagittal plane like the limbs of land mammals. [49]
