Semiaquatic mammals with long tails and webbed feet (6)

I believe the answer is:

otters

(Other definitions for otters that I've seen before include "Mammals with webbed feet" , "River-dwelling mammals" , "Freshwater carnivorous mammals" , "Aquatic carnivores" , "Brown water mammals" .)

I've seen this clue in The Guardian.
