A tenrec is any species of mammal within the family Tenrecidae, found on Madagascar and in parts of the African mainland. Tenrecs are widely diverse; as a result of convergent evolution they resemble hedgehogs, shrews, opossums, mice and even otters. They occupy aquatic, arboreal, terrestrial and fossorial environments. Some of these species, including the greater hedgehog tenrec, can be found in the Madagascar dry deciduous forests.
