Correct!!!!!!Both mammals and birds are warm-blooded animals. Being warm-blooded means that their temperatures are internally regulated.

Click to continue!Amazing AmphibiansMost Amphibians live in or around freshwater habitats such as swamps, ponds, or damp environments, although some have adapted themselves to survive on trees, rocks or underground.Amphibians start their life in water with gills and tails. They then go through metamorphosis- or change- in which they develop lungs and legs for their lives on land.Amphibians have webbed feet. Amphibians have soft, smooth, mucus-covered skin and sticky tongues which help them catch prey.Like fish, amphibians are also cold blooded. Amphibians are carnivorous. They feed on spiders, worms, insects , crustaceans, small reptiles and smaller amphibians. There are close 8,240 different kinds of amphibians including frogs, toads, salamanders and blindworms. Amphibians lay eggs in either water or moist areas such as cracks in the ground.Click to view some amphibians!

Rigid Reptiles!Reptiles generally live on land, usually in dry and warm places. Although some may live in water, water is not needed for developmental nor reproduction reasons. Reptiles include snakes, alligators, crocodiles, tortoises and lizards.Reptiles are cold-blooded. Reptiles have lungs which they use to breathe. Most reptiles are carnivorous and they usually swallow their prey whole. They eat insects, other reptiles, and small mammals.There are more than 8,000 species of reptiles.One physical feature that all reptiles have in common is dry, glandless skin which is covered by scales which protect the body of the reptile. Most reptiles lay eggs. The first reptile is believed to have evolved 320 million years!Click to see some reptiles!

Beautiful Birds!Birds have feathers, wings and beaks, but no teeth. Birds lay eggs.Birds are warm blooded,There are over 10,000 different species of birdsScientists believe that birds evolved from theropod dinosaurs!Birds have hollow bones which help them fly. The chicken is the most common species of bird in the world!Hummingbirds can fly backwards. 75% of birds die before they are 6 months old. Migrate in winter to warmer climates.Click to see some birds!

Marvelous Mammals!Mammals live in all kinds of environments. The ocean, underground, and on land.Some mammals such as bats can fly. Mammals are warm-blooded. Mammals have fur or hair.Mammals have milk-producing glands. Most mammals have teeth.Mammals give birth to live young. Mammals include humans, dogs, whales, elephants and horses to name a few.Mammals can be carnivores (polar bears), herbivores (cows) or omnivores (humans). Mammals can give birth to live young (humans and tigers), carry their young in a pouch (kangaroo and koala bear) or lay eggs (platypus and anteater).
