Webbed toes is the informal and common name for syndactyly affecting the feet—the fusion of two or more digits of the feet. This is normal in many birds, such as ducks; amphibians, such as frogs; and some mammals, such as kangaroos.
Webbed feet of a mute swan. Here, the delta (triangular) shape of the foot is clearly visible. This shape allows for the formation of leading edge vortices and lift-based propulsion during swimming. [1] The webbed foot is a specialized limb with interdigital membranes (webbings) that aids in aquatic locomotion, present in a variety of tetrapod ...
Typically, true frogs are smooth and moist-skinned, with large, powerful legs and extensively webbed feet. The true frogs vary greatly in size, ranging from small—such as the wood frog (Lithobates sylvatica)—to large. Many of the true frogs are aquatic or live close to water. Most species lay their eggs in the water and go through a tadpole ...

In addition, the musculoskeletal foot arch and sole cushion of the elephant act in concert, similarly to the horse's cushioned frog and hoof [6] and the human foot. [29] In the elephant, the nearly half-cupula-shaped arrangement of the bony elements of the metatarsals and toes has interesting similarities to the structure of the arches of human ...
