forked tails

Divided rear appendages

Forked tails are tail structures that divide into two or more prongs, common in birds like swallows and some fish species.

The shape aids aerodynamic or hydrodynamic efficiency.

In folklore and religious imagery, forked tails are associated with devils and demons: a creature with horns and a forked tail.
