The common warthog (Phacochoerus africanus) is a wild member of the pig family found in grassland, savanna, and woodland in sub-Saharan Africa. [ 1 ] [ 2 ] In the past, it was commonly treated as a subspecies of P. aethiopicus , but today that scientific name is restricted to the desert warthog of northern Kenya , Somalia , and eastern Ethiopia .
Size: A head-and-body length ranging from 0.9 to 1.5 m (2 ft 11 in to 4 ft 11 in), and shoulder height from 63.5 to 85 cm (25.0 to 33.5 in). Females, at 45 to 75 kg (99 to 165 lb), are smaller and lighter than males, at 60 to 150 kg (130 to 330 lb). [7] Habitat: Diet: LC Desert warthog Phacochoerus aethiopicus (Pallas, 1766)
The desert warthog is an important host of the tsetse fly, [10] [11] and in some parts of its range efforts are being made to reduce warthog numbers because of this. [11] Specifically, P. aethiopicus was the preferred host for Glossina swynnertoni and G. pallidipes in a study by Weitz 1963.
The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body.
Many dogs (family Canidae) and bovids take about a year to reach maturity while primates (including humans) and dolphins (Delphinidae) require more than 10 years. Some whales take even longer, with the longest duration being recorded for the bowhead whale ( Balaena mysticetus ), which reaches maturity at an age of only about 23 years.
Embryonic diapause [a] (delayed implantation in mammals) is a reproductive strategy used by a number of animal species across different biological classes.In more than 130 types of mammals where this takes place, the process occurs at the blastocyst stage of embryonic development, [1] and is characterized by a dramatic reduction or complete cessation of mitotic activity, arresting most often ...
Metridiochoerus was a large animal, 1.5 metres (4.9 ft) in length, resembling a giant warthog. It had two large pairs of tusks which were pointed sideways and curved upwards. [ 4 ] The teeth, especially the third molars, become increasingly high crowned ( hypsodont ) in later species.
A few mammalian species, such as rabbits, do not have an estrous cycle, instead being induced to ovulate by the act of mating and are able to conceive at almost any arbitrary moment. Generally speaking, the timing of estrus is coordinated with seasonal availability of food and other circumstances such as migration, predation etc., the goal ...
