Amphibians http://www.youtube.com/watch?v=LTFmOEy6M-o

Amphibians Includes frogs, salamanders and caecilians All amphibians are carnivorous, Frogs and salamanders capture prey with their tongues

Amphibians Bony skeleton Usually 4 limbs (tetrapod) Webbed feet often present Skin usually smooth and moist with many glands Some with poison glands Respiration by lungs, skin, and gills Ectotherms (rely on outside heat sources)

Amphibians Use both aquatic and terrestrial habitats Life cycle involves semi-terrestrial adults that breed and lay eggs in water. Some undergo metamorphosis

Order Gymnophiona Caecilian No legs Burrow in soil Long, slender body, small scales Internal fertilization; eggs deposited in moist ground near water Do not go through metamorphosis

Caecilians – legless amphibians

Order Urodela Tailed amphibians Oura – tail; delos – evident Internal fertilization but lay eggs in water or moist soil Newts and salamandars

Tiger salamander

Northwestern salamander

Clouded Salamander

Green salamander

Cave salamander

Warty Newt

Eastern Red Spotted Newt

Order Anura Frogs & Toads An – without; orua - tail Internal fertilization Undergo metamorphosis Vocalizations are used for male for courtship and establishing territories Live near water

Order Anura
