Afrosoricida
Afrosoricida, from Latin Āfrica (“Africa”) and Latin sorex (“shrew, shrew-mouse”), means “looking like African shrews”, in reference to the fact that these animals have a strong similarity with shrews (Eulipotyphla order, Soricidae family).
Common names of members
Golden moles, tenrecs, and otter-shrews.
Distribution
Golden moles (Family Chrysochloridae): Southern Africa
Tenrecs (Family Tenrecidae): Madagascar and western central Africa
Otter-shrews (Family Tenrecidae): Sub-Saharan Africa
Size
They tend to be small animals varying from 4 cm to 39 cm in length.
Morphology
Certain species bear some ecological similarity to hedgehogs, soricid shrews, or miniature otters. Their coat can vary from smooth to spiny and the coloration of the fur can also vary from brown to gray, with v-shaped ridge upper molars. They have cloaca (a single opening for excretion and sexual intercourse) and males lack a scrotum.
Ecology & Habitat
Golden moles (Family Chrysochloridae): Subterranean, living in a variety of environments, such as forests, swamps, deserts and mountainous terrains.
Tenrecs (Family Tenrecidae): Forests and other closed environments.
Otter-shrews (Family Tenrecidae): Freshwater aquatic microhabitats in the rainforest. Preferred environments include fast flowing rivers, streams, swamps, and coastal rivers.
Diet
Golden moles (Family Chrysochloridae): carnivorous, small insects and earthworms or small vertebrates such as lizards or burrowing snakes.
Tenrecs (Family Tenrecidae): omnivorous, with invertebrates forming the largest part of their diets.
Otter-shrews (Family Tenrecidae): carnivorous, preying on any aquatic animal, particularly insects.
Reproduction
Golden moles: Females will use grass to make a nest in the underground burrow. Each female gives birth to 1-3 offspring during each reproduction.
Tenrecs: Most of the tenrecs have a large litter size (up to 30 babies).
Otter-shrews (Family Tenrecidae): They give birth to one or two young per litter, once or twice a year. Males move long distances via water in search of mates and it is thought that males rut (or fight) during the wet season.
