What defines the classic weasel morphology that proved successful for exploiting tight spaces?
Answer
Elongation and flexibility
The success of the weasel body plan is attributed directly to its core morphology, specifically characterized by elongation and flexibility. This physical structure provides a significant evolutionary advantage, allowing these animals to pursue prey deep underground or into narrow crevices where larger, less pliable predators cannot gain access. This fundamental design is maintained across many members of the *Mustelidae* family, even those that have specialized for different environments, such as aquatic or digging niches, demonstrating that this ancestral elongation provided a highly effective template for terrestrial exploitation.
