“Leopardus pardalis” is the ocelot’s taxonomic name, which means “like a leopard,” though leopards do not live in the same areas. Their name comes from the Aztec "tlalocelot," meaning “field tiger”.
Otters sleep sometimes in a den above ground which is called a ‘couch’. But they usually use underground ‘holts’, which they dig out of a river bank or a cavity under riverside tree roots. Pups are born in holts.
