Myurus

Myurus is a genus of small to medium-sized mammals belonging to the family Mustelidae, which includes weasels, badgers, otters, and skunks. The genus is native to the Americas, with species ranging from Canada to Argentina. Myurus species are known for their distinctive long, slender bodies, short legs, and a bushy tail. They have a semi-aquatic lifestyle, often inhabiting wetlands, marshes, and rivers.

The genus includes two recognized species: Myurus minimus, commonly known as the least weasel, and Myurus tarapacensis, known as the tarapacá weasel. Both species are solitary and nocturnal, feeding primarily on small mammals, birds, and insects. They are also known to scavenge for carrion.

Myurus species are generally considered to be of least concern by the IUCN, as they have a wide distribution and are not currently facing significant threats. However, habitat loss and degradation due to human activities can pose a risk to their populations. Conservation efforts are focused on protecting their natural habitats and reducing human-wildlife conflict.

The scientific name Myurus is derived from the Greek words "myos" meaning mouse, and "oura" meaning tail, reflecting the species' small size and bushy tail. The genus was first described by the French zoologist Georges Cuvier in 1825.
