  3. Fun Fishy Facts! • Fish live in water. Fish can live in either saltwater or freshwater depending on their environmental needs. • Fish are cold-blooded, meaning their internal body temperature changes as the surrounding temperature changes. • Fish have gills which bring in oxygen from the water around them. • Fish are covered in slimed covered scales which help them move easily in the water. • Fish eat other fish, fish eggs, mollusks, aquatic plants, algae, plankton, insects, water birds, turtles, frogs, snakes and mice. • Fish have been on the earth for over 500 million years…that’s even before dinosaurs!!! • There are believed to be over 29,000 species of fish which makes them the most diverse grouping of vertebrates! • There are believed to be over 29,000 species of fish which makes them the most diverse grouping of vertebrates! • There are more species of fish than of all species of amphibians, reptiles, birds and mammals combined!

  5. Amazing Amphibians • Most 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.

  7. 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!

  9. 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 birds • Scientists 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.

  11. 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).
