One of the most interesting insect-eating mammals in South America is the Southern Tamandua (Tamandua tetradactyla), also known as the lesser or collared anteater. It is a medium-sized and arboreal species belonging to the family Myrmecophagidae and has fascinated the wildlife enthusiasts over decades with its peculiar adaptations and the animal's nocturnal life. Although its territory is mostly limited to South American forests and savannas, Southern Tamanduas are also present in numerous zoos of the USA, which can provide Americans with an opportunity to witness their fascinating habits.
Southern Tamanduas can be easily identified by the presence of prehensile tails, which serve as the fifth limb during tree climbing. Their lengthy foreclaws enable them to rip apart termite holes and ant nests, and a sticky, lengthy tongue allows them to pick insects with accuracy. They are very efficient predators of ants and termites even though they are very tiny creatures of giants and feed on thousands of insects during a single night.
Southern Tamanduas are also solitary and mainly nocturnal behaviorally, where they use their sharp sense of smell to find prey as opposed to their eyesight. They mark out territory with scent, and they can defend themselves with their sharp foreclaws when they are threatened. These changes have given them the title of being the secret acrobats of the canopy as a highlight of their flexibility and prowess in the trees.
