Frogs generally jump or hop to get about. 'Rocket Frogs'
are so called because how fast and far they can jump. The
Black-Spotyed tree Frog (Hyla nigromaculata) is only
1.2 inches ling, but can jump a staggering 5 feet! But other
frogs know as Walking Frogs, get aroung only by walking slowly.
And Narrow-mouthed Toads (Breviceps sp.) creap and
crawl to their destinations.
Frogs and Toads have only five to ten vertebrae and almost
no neck. Their front and back are fused together and also
two bones in their ankles. This helps them leap as it reduces
the stress on the bones. To compensate for their little neck
movement most frogs have developed large eyes, giving them
almost 360' vision.
Hands and Feet
Frogs and toads have four fingers (front limb digits)
and five toes (hind limb digits). Some aquatic species
have webbing between digits to aid swimming. And the
Flying Frog (Rhacophorus) can actualy glide from
tree to tree with its modified webbing.
Two species have opposable thumbs. And African Clawed
Frogs and the Burrowing toads both have thickened covering
or keratinized finger tips resembling Nails (or claws).
