swahili: Muhanga

A thickset animal with a rounded body, a long, tapered tail, and a small, pig-like head with a very long nose and ears. Th e body colour ranges from light brown to pinkish-grey and the legs are black. Young animals are usually quite hairy, while adults may be mostly hairless on the back. Th ere are four large claws on the front foot and fi ve on the hind foot. Males and females are the same size.

Subspecies Four subspecies are listed for Tanzania: O. a. lademanni, O. a. matschiei, O. a. observandus and O. a. ruvanensis, although their validity is doubtful due to signifi cant intra-specifi c variation.

Similar species Unlikely to be mistaken for any other mammal.

Ecology and social behaviourAardvarks are found in a wide variety of habitats, including open grassland, woodland, thicket, lowland and montane forest, montane grassland and agricultural land. Th ey avoid rocky terrain, which is diffi cult to dig. Th eir diet consists mainly of ants and termites, as well as beetle pupae and larvae. Aardvarks dig into termitaria using their powerful front claws, licking up the invertebrates with a long, sticky tongue. Th ey are solitary and exclusively nocturnal: camera trap records from Tanzania show highest peaks of activity between midnight and 5:00 a.m. Recorded home range sizes vary between 2–5 km2 (0·8–2·0 mi2) with size probably related to food density. Individuals may travel several kilometres in a night in search of food. Th ey frequently dig large, deep feeding burrows, which will be jarringly familiar to anyone who has driven off -road in East Africa. Burrows used for shelter can be very large, with multiple entrances, and may be occupied over long periods of time. Active burrows may be recognized by the presence of fl ies and fresh diggings.

Distribution in TanzaniaAardvarks are very widespread in Tanzania. Th ey have been recorded in all mainland National Parks, with the exception of Rubondo and Gombe, and they are known from the majority of Game Reserves in the country.

Population size and conservation status Th is species probably occurs at low densities across most of its range, although it is likely to be more common where termites are abundant, including much of western Tanzania. It is common in Sumbawanga Rural and Nkasi Districts down to the Zambian border. It frequently inhabits agricultural areas, and is found in coff ee plantations on the outskirts of Arusha.

Orycteropus aferAardvark

Least Concern

HB: 100–130 cm (39–67")

Ht: 60–65 cm (24–26")

Tail: 44–60 cm (17–24")

Wt: 50–80 kg (110–176 lb)

Where to lookAlthough relatively common in some places, the Aardvark’s shy nature and nocturnal habits means it is seldom seen . They are occasionally observed on night drives on Manyara Ranch and Ndarakwai Ranch .

this species suggests it is relatively common in the lowland forests of Mahale NP and in Ugalla GR. Population trends are unknown, although probably stable in protected areas.

Habitat loss poses the main threat to this species, and it is hunted for food in parts of western Tanzania.
