World Tapir Day (WTD) occurs every 27 April to highlight tapirs – long-snouted herbivorous mammals, species of which can be found in South America, Central America and South East Asia. The WTD organisation says that tapirs are "one of the least recognised species of animals", despite their large size and ecological importance.

According to the IUCN Red List of Threatened Species, all tapir species are endangered and their population is continuing to decrease. "The destruction of forests into small, isolated enclaves and the encroachment of human activity into pristine forests affects all native species. However, as the largest – yet perhaps the quietest – of animals in their ranges, tapirs disappear without trace with countless other species," says WTD.

But with their snuffly, long noses and pig-like body, what isn't to love? Here are some pictures of tapirs being really, very, so adorable, to celebrate their special day.
