What is vocal sac inflation in frogs?
Quick Answer
Vocal sac inflation is when a frog expands a throat sac to amplify its call.
The Full Story
Many male frogs produce loud calls during the breeding season, and the vocal sac helps project those sounds. Air is pushed from the lungs over the vocal cords and into the sac, which acts like a resonating chamber. The inflated sac can make the call louder and help attract mates over long distances. Different frog species have differently shaped vocal sacs, and some have more than one sac.
