VertebratesAmphibians, fishes, birds, reptiles, marsupials, monotremes, and placental mammals
Amphibians• Animals that start their lives in water and then
move onto land. • Frogs, salamanders
Reptiles• Animals that are designed to conserve water from
their skin, kidneys and eggs. • Snakes• Turtles• Lizards• Alligators and crocodiles

Monotremes: mammals that lay eggs (Platypus and 2 spiny anteaters)
Marsupials: infant develops in a pouch (koala bear, kangaroos, opossums)
FishThese are animals that obtain oxygen through their gills and live in water.
Jawless fish have no jaws or scales: eels, lamprey, catfish
Cartilaginous fish have jaws, scales and a skeleton made of cartilage; sharks, skates & rays
Bony fish have jaws, scales a pocket on each side of the head (for holding the gills) and a skeleton of hard bones. This includes trout.
For the Re-take quiz Friday:You must know: What kind of animals are found in which
class & What are the characteristics of animals in each class
Hint: Look in your notes-you just wrote it down!
