Umbra, a world record-holding dog, can swim 4 miles (6.4 km) in 73 minutes, placing her in the top 25% in human long-distance swimming competitions. [35] The fishing cat is one wild species of cat that has evolved special adaptations for an aquatic or semi-aquatic lifestyle – webbed digits.
They are clumsy on land, and move on land by lunging, bouncing and wiggling while their fore-flippers keep them balanced; [29] when confronted with predators, they retreat to the water as freshwater phocids have no aquatic predators. [48] The pygmy hippopotamus has four weight-bearing limbs, and can walk on land like a fully terrestrial mammal.
In walking, and for many animals running, the motion of legs on either side of the body alternates, i.e. is out of phase. Other animals, such as a horse when galloping, or an inchworm, alternate between their front and back legs. In saltation (hopping) all legs move together, instead of alternating. As a main means of locomotion, this is ...
These animals include sessile organisms (e.g. sponges, sea anemones, corals, sea pens, sea lilies and sea squirts, some of which are reef-builders crucial to the biodiversity of marine ecosystems), sedentary filter feeders (e.g. bivalve molluscs) and ambush predators (e.g. flatfishes and bobbit worms, who often burrow or camouflage within the ...
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 ...
This suborder of fish also use a labyrinth organ to breathe air. Some species from this group can move on land. Amphibious fish from this family are the climbing perches, African and Southeast Asian fish that are capable of moving from pool to pool over land by using their pectoral fins, caudal peduncle, and gill covers as a means of locomotion.
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 ...

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).
