Darwin suggested that manes were used to protect the male during fights, however, there is greater advantage of avoiding a fight altogether. The study also found a correlation between mane length and colour and several ecological factors; in males over five years of age, mane length was closely associated with injury, leading to a possible signal that a short mane was an indication of lower fighting ability. Intercellular parasites include protozoa, trematoda (flatworms), cestoda (tapeworms), nematode (roundworms), acanthocephalan (thorny-headed worms) and arthropoda. The FCV strain usually causes temporary infection and appears to be harmless in most cases. The major tissues of the lions circulatory system are the muscle, the spleen, the heart . Rath.

After moving through the pyloric sphincter, food next travels to the duodenum which is the most anterior part of the small intestine. Males avoided the dark maned males, and were extremely sensitive to mane length, avoiding the longer maned dummy. Diseases can be classified as endemic or epidemic dependant on their persistence in a population. In the wild, lions usually live no more than 8 to 10 years because of attacks by humans or other lions, or the effects of goring or kicks from intended prey.
