Diving adaptations[ edit ] Sea lion heart. There are many components that make up sea lion physiology and these processes control aspects of their behavior.
Mane colour varies and darkens with age; research shows its colour and size are influenced by environmental factors such as average ambient temperature.
Mane length apparently signals fighting success in male—male relationships; darker-maned individuals may have longer reproductive lives and higher offspring survival, although they suffer in the hottest months of the year.
The presence, absence, colour and size of the mane are associated with genetic precondition, sexual maturity, climate and testosterone production; the rule of thumb is that a darker, fuller mane indicates a healthier animal. In Serengeti National Parkfemale Lions in jungle favour males with dense, dark manes as mates.
The hormone testosterone has been linked to mane growth; castrated lions often have little to no mane because the removal of the gonads inhibits testosterone production.
In the Chauvet Cave is a sketchy drawing of two maneless lions that appearing to be walking side-by-side. One lion is mostly obscured by the other; the obscuring lion is larger than the obscured one and is depicted with a scrotum.
White lion White lions owe their colouring to a recessive allele The white lion is a rare morph with a genetic condition called leucism that is caused by a double recessive allele. It is not albino; it has normal pigmentation in the eyes and skin. They were removed from the wild in the s, thus decreasing the white lion gene pool.
Nevertheless, 17 births have been recorded in five prides between and Intermittent bursts of activity continue until dawn, when hunting most often takes place. Such a group is called a " pride ". Groups of male lions are called "coalitions".
Large prides, consisting of up to 30 individuals, have been observed. A lion may switch lifestyles; nomads can become residents and vice versa.
Females lions stay closer to their natal pride. Therefore, female lions in an area are more closely related to each other than male lions in the same area. The reasons for the development of sociality in lionesses — the most pronounced in any cat species — are the subject of much debate.
Increased hunting success appears to be an obvious reason, but this is uncertain upon examination; coordinated hunting allows for more successful predation but also ensures non-hunting members reduce per capita calorific intake.
Some females, however, take a role raising cubs that may be left alone for extended periods. Members of the pride tend to regularly play the same role in hunts and hone their skills.Classroom theme activities are available in the following categories.

The lion is the "King of Beasts" (very longstanding tradition), the lion is from Africa, all Africa is a "Jungle" filled with guys in pith helmets and savage natives, ergo "Lion is the king of the Jungle".

Sidebar Nav Lion, The King of the Jungle Lion Species. These kings of the jungle can weigh between and pounds, depending on sex and age and can grow up to be 14 years old in the wild and over the age of 20 years old in captivity.
So why are lions the kings of the jungle? Lions are the kings of the jungle because of their raw power and strength. Lions fear no other animals, however, like a king lions do have enemies. The lion's worst enemy is the hyena. Hyenas eat the same food as lions, so the lions and the hyenas often come into conflict over food.
