Research overview: the jaguarundi and its placement in the puma lineage

The jaguarundi is an unusual, weasel-like small cat of the Americas whose taxonomy was clarified by molecular phylogenetics. This overview explains how genetic data placed the jaguarundi in the puma lineage as the close relative of the puma and cheetah, often in the genus Herpailurus or Puma. It discusses how its distinctive elongated body, uniform coat, and lowland habits long obscured its relationships, which appearance alone could not resolve. The piece highlights how the jaguarundi exemplifies the puma lineage's surprising composition, uniting cats of very different form and ecology by shared ancestry. It connects to broader felid systematics, where molecular tools repeatedly revealed that morphological resemblance, here the jaguarundi's atypical look, is a poor guide to evolutionary relationships among cats.
