World Otter Day

World Otter Day is celebrated annually on the last Wednesday of May. It was created to raise awareness of the conservation status of otters since more than half of all extant otter species are classified as threatened by the International Union for Conservation of Nature (IUCN).

Otters are carnivorous mammals that form the subfamily Lutrinae of the family Mustelidae, which also includes badgersferrets, wolverines, martens, polecats, weasels, minks, and ermines, among other animals. There are 13 extant otters species that are all semiaquatic, aquatic, or marine. These cute, playful animals play an important role in ecosystems because their position as top predators helps prevent overpopulation of invertebrates and preserve kelp forests.
