What lives in a holt

Otter
An otter's den is called a holt or couch. Male otters are called dogs or boars, females are called bitches or sows, and their offspring are called pups.[4] The collective nouns for otters are bevy, family, lodge, romp (being descriptive of their often playful nature) or, when in water, raft.

The feces of otters are typically identified by their distinctive aroma, the smell of which has been described as ranging from freshly mown hay to putrefied fish;[7] these are known as spraints.
