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 are the result of mutations in genes that normally cause interdigital tissue between the toes to apoptose. [8] Apoptosis, or programmed cell death, in development is mediated by a variety of pathways, and normally causes the creation of digits by death of tissue separating the digits.
Five types [3] of syndactyly have been identified in humans. The corresponding loci associated with these types and their common phenotypical expression are as follows: . type I: 2q34-q36; [4] webbing occurs between middle and ring fingers and/or second and third toes.
An example of interdigital webbing on an Abah River flying frog.. In oryzomyines, a mainly South American rodent group, the marsh rice rat, Pseudoryzomys simplex, and Sigmodontomys alfari all have small webs, which do not extend to the end of the proximal phalanges, whereas Amphinectomys savamis, Lundomys molitor and the members of the genera Holochilus and Nectomys have more expansive webbing ...

An "amphibious mouse" with partially webbed feet that eats aquatic insects was among 27 new species discovered during a 2022 expedition to Peru's Amazon, according to Conservation International.
Split hand/foot malformation (SHFM) is characterized by underdeveloped or absent central digital rays, clefts of hands and feet, and variable syndactyly of the remaining digits. SHFM is a heterogeneous condition caused by abnormalities at one of multiple loci, including SHFM1 (SHFM1 at 7q21-q22), SHFM2 (Xq26), SHFM3 (FBXW4/DACTYLIN at 10q24 ...
