The see-through skin of an 2.5-centimeter-long glass frog reveals her eggs. Native to Venezuela, the frogs lay eggs in bushes and trees overhanging streams. Tadpoles hatch, then tumble into the current to be swept away.
A two-headed albino Honduran milk snake is shown in Ridge Manor, Florida. Snake of this species are normally orange and black. Daniel Parker, a University of Central Florida biologist, says two-headed snakes have been documented to live as long as 20 years in captivity. But with two brains giving commands to a single body, Parker says the snake would have a difficult time surviving in the wild.
