How many species are estimated to comprise the family *Mustelidae* within the order Carnivora?
Answer
Around 56 species across 25 genera
The family *Mustelidae* represents one of the most speciose groups within the larger order Carnivora, demonstrating the long-term evolutionary success of its members. Quantitatively, the family is estimated to encompass approximately 56 distinct species. These species are categorized across 25 recognized genera, illustrating a broad occupational range of ecological niches globally. This high species count is a direct result of the flexibility of the ancestral body plan, which allowed for subsequent evolutionary adjustments to suit environments ranging from Arctic conditions to tropical rainforests.
