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.
There are two types of animal locomotion on water, determined by the ratio of the animal's weight to the water's surface tension: those whose weight is supported by the surface tension at rest, and can therefore easily remain on the water's surface without much exertion, and those whose weight is not supported by the water's surface tension at ...
They are the least specialised of all the seabirds, and their morphology allows for equal adeptness in swimming, flying, and walking. They are more adept walking on land than most other seabirds, and the smaller gulls tend to be more manoeuvrable while walking. The walking gait of gulls includes a slight side to side motion, something that can ...
Loons swimming in Wood Lake, BC on a summer morning. Loons are excellent swimmers, using their feet to propel themselves above and under water. However, since their feet are located far back on the body, loons have difficulty walking on land, though they can effectively run short distances to reach water when frightened.
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 ...
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 ...
