Owner of the most commonly found shell on all beaches, the slipper snail is also the holder of a rather odd record: the longest daisy chain in the animal kingdom. Scientifically named Crepidula fornicata for a good reason, all slipper snails begin life as males. When a snail reaches sexual maturity, it attaches itself to an object, and performs an impromptu sex change on itself, becoming female. Soon, another male snail comes along, mates with the first one, and stays mounted on the first one for the rest of its life. Then, it too becomes female, and the chain continues. Along comes a third snail, and it continues the chain. Chains of up to 14 snails have been found.
