Characteristics• Amphibians= larval part of their life in water and their adult lives
partially or completely on land• 4,000 species exist• Have thin skin they can breathe through with the process of
osmosis– Most skins are filled with fluid-secreting glands that produce a slimy
mucus• Purpose of moisture• Prevents too much water from being absorbed into the body when the animal
is in the water• Defense
• Tongues vary considerably– None– Very long and sticky tips– Don’t have teeth

Handling• Toads and Frogs- Grasp around body• When amphibians are transported they should be
placed in a moist cloth bag to prevent excess moisture loss
• Some frogs and toads produce toxins- – wash your hands before to prevent harming them and
wash your hands after you prevent harming you
• Salamanders- Run water over your hands before picking them up
• Do not grasp by tail (they release their tails)
