OstheicthyesBony fishectothermic (cold blooded), aquatic vertebrates.skin is covered with scales.limbs - fins for swimming.breathe with gills. External fertilization - lay eggs that must be in water.
AMPHIBIANSFROGS, TOADS, NEWTS, SALAMANDERSectothermic vertebrates.skin is either smooth (like a frog) or rough (like a toad).dependent upon moisture and subject to desiccation; their skin must remain moist to aid in breathinglay eggs in water, which hatch into an intermediate life form (tadpole or larva) that usually breathes with gills, and change into the adult form that breathes air and can live outside water. three-chambered hearts.lack claws on their toes.
RED SPOTTED NEWT
REPTILESSnakes, lizards, turtles, gatorsectothermic vertebrates. skin has scales, but no hair or feathers.three-chambered hearts (except for alligators and crocodiles, which have four-chambered hearts).claws on their toes first animals, in evolution, to develop the amniotic egg. This allows reptiles to lay eggs on land.
Amnionic Egg (shelled egg)
BIRDSendothermic vertebrates.skin is covered with feathers. four-chambered hearts.bones are lightweight and usually hollow.forelimbs are modified as wings. lay eggs.
MAMMALSendothermic vertebrates.Body covered with hair, which varies greatly among species.Most have sudoriferus (sweat) glands.have mammary (milk-secreting) glands.sebaceous (fat-secreting) glands.have heterodont dentition (different types of teeth).
