Like fish, these frogs have a lateral line sensory system running from head to vent. Under normal circumstances, Xenopus frogs never leave the water, although they have occasionally been known to migrate if their home pond dries up. These frogs are well suited for aquatic life, able to swim in all directions, including backwards, with ease. Air-breathing, they depend on well developed lungs. They have a flat body, a head smaller than their body, eyes on top of their head, and the eyes are small, round and lacking eyelids.
Front limbs are small and unwebbed with their four fingers sticking out stiffly from the body.
Color Pattern Xenopus are multicolored, with their backs in various shades of olive gray with large gray blotches. Calls Both the males and females call from underwater. Despite the fact males have no vocal sacs, they can be heard at distances of 100 yards. Reproduction Breeding among frogs in the genus Xenopus contains both primitive and highly specialized elements. This is where the male grasps the female with his forearms just above her hind legs.
