interdigital webbing

Interdigital webbing may be more highly developed in the palustris group.

Interdigital webbing may be present, but its development is variable within the genus.

Interdigital webbing is present, but extends along less than half of the first phalanges.

Interdigital webbing is the presence of membranes of skin between the digits.

Interdigital webbing is not to be confused with syndactyly, which is a fusing of digits and occurs rarely in humans.

All otters have interdigital webbing, in the fore or hind limbs or both, to aid in aquatic propulsion.

The large hindfeet are characterized by conspicuous interdigital webbing, but they lack tufts of hair on the digits and several of the pads are reduced.

The Water Opossum (Chironectes minimus) of South America is the only opossum with interdigital webbing.

Webbing: Webbing (textile), Interdigital webbing (Biology).

The African semiaquatic rodents Colomys goslingi and Nilopegamys plumbeus, also members of the Murinae, lack interdigital webbing.

It is similar to Nectomys, but its discoverers considered it to be different enough (with more expansive interdigital webbing and a significantly broader interorbital region) to require its own genus.

The severe generalized subtype, associated with formation of pseudosyndactyly (a mitten-like deformity secondary to fusion of interdigital webbing) in early childhood, carries a SCC risk of up to 85% by the age of 45.

Pits present on the sides of fossil proximal phalanges of pakicetids, ancestral whales, suggest that these animals had interdigital webbing, a development hypothesized to lead to the fluke, spurred by FGF8, a Fibroblast growth factor.

The tenrec family, which occurs in Africa and mainly on Madagascar, includes several semiaquatic forms, and the small otter-shrews (Micropotamogale) and the aptly named Web-footed Tenrec (Limnogale mergulus) have developed interdigital webbing.

The three genera share several characters, including specializations towards a semiaquatic lifestyle, such as the presence of membranes between the digits (interdigital webbing), and a reduction in the complexity of the molar crowns, both of which are at incipient stages in Pseudoryzomys.

B. rigbyae was first described in 2009 based on specimens found in Antarctic trawling surveys near the Antarctic Peninsula, and, while similar in appearance, differs from B. levis in its arm length, the depth of its interdigital webbing and specific details of its hectocotylus.

Among shrews, the members of the genera Chimarrogale of southeastern Asia and Neomys of western Eurasia have interdigital webbing, as does the American Water Shrew (Sorex palustris) of North America, but it is more well-developed in Nectogale elegans of montane Asia.
