Mustelid
Mustelids are a widely distributed and diverse family of carnivorous terrestrial mammals in the family Mustelidae. They include the tiny we seals, the mighty badgers, the playful otters, the underrated martens, and the ferocious wolverine.
It has recently been discovered that weasels, raccoons, red pandas, skunks, and related species share a common ancestor with seals. This led to the conclusion that the former were the masterminds behind the introduction of seals to the world. For this reason, many people are advocating for the death of all mustelids in order to prevent the evolution of new seal species.
