Recovery from this state is accompanied by shivering at a frequency of 58 muscle contractions/sec. [3] This induces heating at a rate of up to 0.83 °C/min, which is among the highest values recorded in mammals; the heart rate increases exponentially with time from 100 to 800–1,200 beats/min, and the respiratory rate rises linearly from 50 to ...
Precocial mammal species generally have greater adult body weights than altricial mammals as precocial mammals have markedly longer gestation periods than altricial mammals. [21] The neonatal of larger mammals develop relatively more quickly and thus making it more likely that a large mammal would produce a more well-developed neonate as a ...
Hyraxes are well-furred, rotund animals with short tails. [3] Modern hyraxes are typically between 30 and 70 cm (12 and 28 in) in length and weigh between 2 and 5 kg (4 and 11 lb). They are superficially similar to marmots, or over-large pikas, but are much more closely related to elephants and sirenians. Hyraxes have a life span from nine to ...
In the largest size range studied by Cott, 4–5 m (13 ft 1 in – 16 ft 5 in), they were the second most likely to either have full stomachs (10%) or empty stomachs (20%). [4] Other studies have also shown a large number of adult Nile crocodiles with empty stomachs. For example, in Lake Turkana, Kenya, 48.4% of crocodiles had empty stomachs ...
The dugong (/ ˈ d (j) uː ɡ ɒ ŋ /; Dugong dugon) is a marine mammal.It is one of four living species of the order Sirenia, which also includes three species of manatees.It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century.
A monogastric organism has a simple single-chambered stomach (one stomach). Examples of monogastric omnivores include humans, pigs, hamsters and rats. Furthermore, there are monogastric carnivores such as cats. [1] A monogastric organism is contrasted with ruminant organisms (which have four-chambered complex stomachs), such as cattle, goats ...

Although it is unclear what the maximum weight for colossal squids is, analysis of squid beak dimensions from sperm whale stomachs provided estimates that colossal squids may weigh up to 700 kg or 1,500 lb. [5] [6] The colossal squid also has the largest eyes documented in the animal kingdom, with a diameter of 27–30 cm (11–12 in). [30] [31]
