ORDER ANURA - Frogs and Toads
The distinction between frogs and toads is imprecise. Frogs tend to be moist, slimy and jump, whereas toads tend to be warty, dry and walk. Toads can tolerate drier conditions and have warts and poison glands that contain toxins. Toad warts do not cause warts, but some toxins produced by toads cause heart failure, while others affect the central nervous system. Frogs and toads also differ in the way they lay their eggs. Most frogs lay their eggs in globular masses, while toads lay their eggs in strings.
