"Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic or marine, with diets based on fish and invertebrates. Lutrinae is a branch of the Mustelidae family, which also includes weasels, badgers, honey badgers, martens, minks, polecats, and wolverines." - (en.wikipedia.org 09.03.2020)
