Abnormal behaviour in animals can be defined in several ways. Statistically, abnormal is when the occurrence, frequency or intensity of a behaviour varies statistically significantly, either more or less, from the normal value. This means that theoretically, almost any behaviour could become abnormal in an individual.
Animal stereotype may refer to: . Stereotypy (non-human), repetitive behaviours of animals; the term has two meanings: repetitive "abnormal" behaviours due to abnormal conditions with no obvious function
In animal behaviour, stereotypy, stereotypic or stereotyped behaviour has several meanings, leading to ambiguity in the scientific literature. [1] A stereotypy is a term for a group of phenotypic behaviours that are repetitive, morphologically identical and which possess no obvious goal or function. [ 2 ]
The giraffe's head and neck are held up by large muscles and a nuchal ligament, which are anchored by long thoracic vertebrae spines, giving them a hump. [17] [63] [36] Adult male reticulated giraffe feeding high on an acacia, in Kenya. The giraffe's neck vertebrae have ball and socket joints.
These behaviors are associated with stress and lack of stimulation. Animals that exhibit this tend to suffer from zoochosis, as it is manifested in stereotypical behaviors. [3] Many who keep animals in captivity attempt to prevent or decrease stereotypical behavior by introducing stimuli, a process known as environmental enrichment. The goals ...
The Giraffidae are a family of ruminant artiodactyl mammals that share a recent common ancestor with deer and bovids.This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe (between one and eight, usually four, species of Giraffa, depending on taxonomic interpretation) and the okapi (the only known species of Okapia).
The ethological concept of species-typical behavior is based on the premise that certain behavioral similarities are shared by almost all members of a species. [1] Some of these behaviors are unique to certain species, but to be 'species-typical' they do not have to be unique, they simply have to be characteristic of that species.
The life history of an animal is thus extremely important when analyzing the causes of stereotypical behavior, as this can be a historical relict instead of a result of present-day husbandry. Some zoos have used psychoactive drugs, such as Prozac, in attempting to stop animals from exhibiting the behaviors. [85]
