The Lion Shirt

Manes make males look larger and may serve to intimidate rivals or impress prospective mates. A full-grown male is about 1.8–2.1 metres (6–7 feet) long, excluding the 1-metre tail; he stands about 1.2 metres high at the shoulder and weighs 170–230 kg (370–500 pounds). The female, or lioness, is smaller, with a body length of 1.5 metres, a shoulder height of 0.9–1.1 metres, and a weight of 120–180 kg. The lion’s coat is short and varies in colour from buff yellow, orange-brown, or silvery gray to dark brown, with a tuft on the tail tip that is usually darker than the rest of the coat.Male lion (Panthera leo) in the Masai Mara National Reserve, Kenya.Male lion (Panthera leo) in the Masai Mara National Reserve, Kenya.© Photodisc/ThinkstoclionlionLioness (Panthera leo).© Digital Vision/Getty ImagesPrides
Lions are unique among cats in that they live in a group, or pride. The members of a pride typically spend the day in several scattered groups that may unite to hunt or share a meal. A pride consists of several generations of lionesses, some of which are related, a smaller number of breeding males, and their cubs. The group may consist of as few as 4 or as many as 37 members, but about 15 is the average size. Each pride has a well-defined territory consisting of a core area that is strictly defended against intruding lions and a fringe area where some overlap is tolerated. Where prey is abundant,

a territory area may be as small as 20 square km (8 square miles), but if game is sparse, it may cover up to 400 square km. Some prides have been known to use the same territory for decades, passing the area on between females. Lions proclaim their territory by roaring and by scent marking. Their distinctive roar is generally delivered in the evening before a night’s hunting and again before getting up at dawn. Males also proclaim their presence by urinating on bushes, trees, or simply on the ground, leaving a pungent scent behind. Defecation and rubbing against bushes leave different scent markings.Pride of lions (Panthera leo).Pride of lions (Panthera leo).© Guido Amrein/Dreamstime.comThere are a number of competing evolutionary explanations for why lions form groups. Large body size and high density of their main prey probably make group life more efficient for females in terms of energy expenditure. Groups of females, for example, hunt more effectively and are better able to defend cubs against infanticidal males and their hunting territory against other females. The relative importance of these factors is debated, and it is not clear which was responsible for the establishment of group life and which are secondary benefits.
