Other species will burrow into the ground.
The warty bumps on toads contain chemicals that can repel, sicken, or even kill animals that try to eat them.įrogs and toads survive the winter by hibernatingĪs temperatures begin to drop below freezing, some frog species will seek shelter at the bottoms of lakes and ponds.
Frogs hibernate skin#
Their bellies are lighter in color, making them harder for underwater predators looking up to see against the bright sky. Frogs and toads also have skin glands that produce chemicals which are distasteful and, in some species, may be poisonous. Toads have a dry warty skin and short hind legs and lay their eggs in chains. Frogs have smooth, moist skin and long hind legs and lay their eggs in clusters. Frogs and toads are usually colored in browns or greens, providing good camouflage from predators looking down both in water or on land. Both have wide heads, short bodies, no ribs, and have hip bones and legs specialized for hopping or jumping. Amphibians depend on the outside environment for body heat because they do not produce it internally and have smooth or warty skin that can be quite penetrable, so most species remain in or near water or moist habitats. Amphibians usually lay unshelled eggs in water or moist places, and most species have a gilled larval stage that changes into a lung-breathing adult.
