  • If you've ever checked a pond for tadpoles and saw huge six-inch beasties, they were likely young American bullfrogs. 
  • Like all tadpoles, bullfrog tadpoles live in the water. 
  • They face many predators, including fish, snakes, and birds. 
  • As they grow, the torpedo-shaped tadpoles sprout legs and lose their tails. 
  • In two to four years, the tadpoles emerge from the water as fully-formed bullfrogs.

  • Chameleons are colorful lizards known for their ability to change color, their long sticky tongue and for their eyes. 
  • The eyes of chameleons allow 360˚ vision - can move independently of each other, giving the chameleon the ability to see all round itself when seeking prey, and binocular vision in front when it is preparing to strike with its long, sticky tongue
  • Chameleons five toes are zygodactylous so they can grasp branches just like our thumbs and fingers can grasp objects. 
  • The chameleon's tail can wrap around tree branches while climbing. For this reason, the chameleon's tail cannot be broken off and regrown like those of many other lizards

“...I know it's hard when you're up to your armpits in alligators to remember you came here to drain the swamp” ~ EXPLOREby turtlemom4bacon on Flickr

  • Although Nile crocodiles are imposing—they resemble armored tanks with huge, teeth-filled mouths—these reptiles are unusually attentive parents. 
  • The young crocs live under their mother's protection for up to two years, feeding on insects and small fish and growing about a foot (30.4 centimeters) each year.
  • It all begins when a large male croc spots a female that catches his eye. 
  • He bellows and splashes, slapping his snout on the water to get her attention. 
  • He grunts and growls, and sometimes, inhales as hard as he can, submerging his snout and blowing water through his nostrils, producing a fountain like spray.
