It is therefore highly likely that only the strongest, fittest males can afford to maintain a dark mane. Only infected ticks which carry the disease from feeding on blood from an infected animal transmit the disease. Other members of the pride quickly crowd around to feed on the kill, usually fighting for access. Digestive and endocrine system working together.

This protects their feet from touching the hot ground and keeps their feet cool which in turn helps to control the body's temperature from overheating. Frogs also have skin, meat/flesh like human and they also possess a brain similarly like humans. It is entirely likely that lions, like many other wildlife species, eventually succumb to overload rather than a single pathogen. This suggests that the FCV infection occurs in populations of high density, with outbreaks increasing as the size of the susceptible host population grows. Here, sporogony occurs, resulting in sporozoites that are transmitted to the cat when the tick feeds. has been isolated in lions and is morphologically similar to, ).

Aside from the clinical effects of bTB leading to greater mortality in affected populations the prevalence of the disease within Kruger has also been shown to drive social change with lower lion survival and breeding success with more frequent male coalition turnover and consequent higher infanticide. Theileria are transmitted by ticks. Defecation and rubbing against bushes leave different scent markings.
