A sagittal crest is a ridge of bone running lengthwise along the midline of the top of the skull (at the sagittal suture) of many mammalian and reptilian skulls, among others. The presence of this ridge of bone indicates that there are exceptionally strong jaw muscles. The sagittal crest serves primarily for attachment of the temporalis muscle, which is one of the main chewing muscles. Development of the sagittal crest is thought to be connected to the development of this muscle. A sagittal crest usually develops during the juvenile stage of an animal in conjunction with the growth of the temporalis muscle, as a result of convergence and gradual heightening of the temporal lines. Function A sagittal crest tends to be present on the skulls of adult animals that rely on powerful biting and clenching of their teeth, usually as a part of their hunting strategy. Skulls of some dinosaur species, including tyrannosaurs, possessed well developed sagittal crests. Among mammals, dogs, cats, lions, and many other carnivores have sagittal crests, as do some leaf eaters, including tapirs and some apes. Apes...

The trophic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The path along the chain can form either a one-way flow or a food "web". Ecological communities with higher biodiversity form more complex trophic paths. The word trophic derives from the Greek τροφή (trophē) referring to food or nourishment. History The concept of trophic level was developed by Raymond Lindeman (1942), based on the terminology of August Thienemann (1926): "producers", "consumers", and "reducers" (modified to "decomposers" by Lindeman). Overview The three basic ways in which organisms get food are as producers, consumers, and decomposers. Producers...

The African civet (Civettictis civetta) is a large viverrid native to sub-Saharan Africa, where it is considered common and widely distributed in woodlands and secondary forests. It is listed as Least Concern on the IUCN Red List since 2008. In some countries, it is threatened by hunting, and wild-caught individuals are kept for producing civetone for the perfume industry.The African civet is primarily nocturnal and spends the day sleeping in dense vegetation, but wakes up at sunset. It is a solitary mammal with a unique coloration: the black and white blotches covering its coarse pelage and rings on the tail are an effective cryptic pattern. The black bands surrounding its eyes closely resemble those of the raccoon. Other distinguishing features are its disproportionately large hindquarters and its erectile dorsal crest. It is an omnivorous generalist, preying on small vertebrates, invertebrates, eggs, carrion, and vegetable matter. It is one of the few carnivores capable of eating toxic invertebrates such as termites and millipedes. It detects prey primarily by smell and sound rather than by sight. It is the only living...
