  "description": "Flying Fox bat in a cave. There can never be too many bats - they pollinate our crops and eat insects, especially those nasty mosquitoes that like to eat me :-(  Bats are wonderful creatures that have been maligned by idiotic movies. It's unfortunate that our population gets its education from Hollywood instead of science and nature."
