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.
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 ...
This robot has soft arms that can move, swim, and grasp. The researchers hope this robot will inspire future applications that could aid in underwater exploration, search and rescue missions, and ...
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 ...

Marine iguanas can dive as deep as 30 m (98 ft), [7] and can spend up to one hour underwater. [19] When diving to 7 m (23 ft) or deeper, they regularly remain submerged from 15 to more than 30 minutes. [62] Most dives are much shorter in duration and shallower than 5 m (16 ft). [30]
As a guideline, nekton are larger and tend to swim largely at biologically high Reynolds numbers (>10 3 and up beyond 10 9), where inertial flows are the rule, and eddies (vortices) are easily shed. Plankton, on the other hand, are small and, if they swim at all, do so at biologically low Reynolds numbers (0.001 to 10), where the viscous ...
