Fisher skulls, the skeletal remnants of the weasel family members known as fishers, reveal fascinating anatomical features that reflect their predatory lifestyle. These skulls are characterized by elongated nasal passages, sharp canine teeth, and a robust jaw structure, all of which support their carnivorous diet.

The structure of a fisher skull allows for strong biting power, essential for hunting small mammals and birds. Their zygomatic arches are pronounced, providing attachment points for powerful jaw muscles. This adaptation is crucial for delivering swift and effective kills.
