Rosette (zoology)

From Wikipedia, the free encyclopedia
Rosettes of a jaguar

A rosette is a rose-like marking or formation found on the fur and skin of some animals, particularly cats.[1][2] Rosettes are used to camouflage the animal, either as a defense mechanism or as a stalking tool. Predators use their rosettes to simulate the different shifting of shadows and shade, helping the animals to remain hidden from their prey. Rosettes can be grouped in clusters around other spots, or may appear as blotches on the fur.

Young lion (Panthera leo) cubs have rosette patterns on their legs and abdomen regions. These rosettes usually do not transfer into adulthood and fade as the cub ages. However, some mature lions may keep traces of their rosette patterns throughout life.[5] For the lion cub, the rosette markings act as camouflage in long grasses and bushes. [6]
