Elagus

Elagus is a genus of small to medium-sized mammals belonging to the family Mustelidae, which includes weasels, badgers, otters, and others. The genus is native to the Americas, with species ranging from Canada to Argentina. Elagus is characterized by its long, slender body, short legs, and a bushy tail. The most well-known species is the fisher, also known as the short-tailed weasel or American mink. Fishers are semi-aquatic and are known for their excellent swimming abilities and diet, which primarily consists of fish.

The genus Elagus includes two recognized species: the fisher (Elagus eurasian) and the South American fisher (Elagus ignicollis). Both species are similar in appearance but differ in their geographical distribution and some behavioral traits. Fishers are known for their adaptability and have been introduced to various regions outside their native range, including Europe and Australia, where they have become invasive species.

Elagus species play a role in their ecosystems, serving as both predators and prey. They are also of interest to wildlife enthusiasts and researchers due to their unique adaptations and behaviors. Conservation efforts focus on protecting their natural habitats and managing populations to prevent negative impacts on native species.
