Alternating tandem reels were first invented for <<ddd:The Flight of the Falcon#2222|falcons>> and later reused for <<ddd:Pelorus Jack#5209|dolphins>> but they do very nicely for otters as well. Here 1st couple are the otters. The supporting couples are rocks in the pools for bars 1-8, then fish being chased in bars 9-24 (lucky 2nd couple escape but the hapless 3rd couple get caught, metaphorically eaten and their remains neatly discarded in the corner - sorry!) and finally in bars 25-32 they are flotsam eddying with little vortices in the wake of the departing otters.

The dance was originally a reel, but was later changed to be a jig.
