Threats
The red ruffed lemur has few natural predators.  One of their worst natural predator is the fossa.  The fossa chases them around tree tops and finally catches them.  Humans are another threat to them.  Due to poaching and habitat loss,  the red ruffed lemur's range has greatly decreased.  Their are about 200 red ruffed lemurs in about 42 different zoos worldwide.

Generally, an adult male weighs about 96 kilograms.  Some larger males have been recorded to weigh about 160 kilograms.  Whereas, jaguars which are smaller weigh only 36 kilograms.  Females are generally 10 to 20% smaller than males.  Jaguars have distinct markings on their tan skin color called 'rosettes'.  They normally have a tail which is 75 centimeters long.  Their body color varies from a tawny yellow to a reddish brown or black.  They have rosettes for camouflage in its rainforest habitat.  Jaguars are very stocky and have a very powerful jaw.  They can carry 360 kilograms with its mouth for 25 feet.
