  • Amphibians have backbones.
  • The internal temperature of their bodies varies, depending on the environment .
  • Amphibians spend time in the water and on the land.
  • Their larvae mature in water and breathe through gills.
  • Adults breathe air through lungs and skin and their skin must remain moist to aid in breathing.
  • The skin of amphibians is usually smooth and does not have hair, scales or feathers.
  • They do not have claws on their toes.
  • They have three-chambered hearts.
Amphibians include frogs, toads, and salamanders.The word amphibian was taken from the Greek "amphi" meaning "double" and "bios" meaning "life" which is quite fitting for the animals known as amphibians. These creatures do live a double life. Emerging from eggs that are usually laid in the water, most amphibians begin their life with gills. They soon lose these gills and metamorphose from a completely aquatic form into a more terrestrial form.To date, there are 22 known species of salamanders, frogs, and toads at Catoctin Mountain Park.
