Lions are the only cats that have a tufted tail.
A tuft is a clump of hair at the end of the tail.
Both male and female lions have a tuft on the end of their tail.
In most lions, the tuft hides a hard spur (bony growth), separate from the last vertebra of the tail.
Zoologists think the spur could be a remnant of tail claws found in ancient lion fossils.
