"Weasel-like carnivore" is a broad description. Many carnivores share characteristics with weasels.
Family Mustelidae:
* Weasels: Slender with long bodies, short legs, and thin snouts. Examples include the Least Weasel, Long-tailed Weasel, and Short-tailed Weasel.
* Martens: Larger than weasels with longer legs and bushy tails. Examples: American Marten, Pine Marten, Fisher.
* Minks: Semi-aquatic with webbed feet and streamlined bodies.
* Badgers: Stockier but still mustelids with long bodies and powerful claws.
* Otters: Fully aquatic mustelids with long, slender bodies.
Other carnivore families:
* Mongooses: Slender, long-bodied carnivores with a similar hunting style, though not closely related.
* Ferrets: Domesticated from European polecats, similar in size and shape to weasels.
