Vertebrates

  1. 1. 1. They live in the water and nearly all these animals have scales. H I E S S F 2. Animals with mammary glands. 3. Only animals with feathers. 4.They can live both on land and in water. 5. Scaly animals that are hatched from eggs with hard shells. L A M M A S M D R I B S P E R I T S L E S H I N M A P I B A F I S H E S M A M M A L S B I R D S A M P H I B I A N S R E P T I L E S

  4. 4. Characteristics of Each Groups of Vertebrate FISHES Fish has fins, which are think bony sheets arranged all over its body. All fish with the exemptions of the lung fish, have gills
  5. 5. Characteristics of Each Groups of Vertebrate AMPHIBIANS They live on land and in water. They live in water when they are still a babies and on land when they grow-up.
  6. 6. Characteristics of Each Groups of Vertebrate REPTILES Are scaly animals that are hatched from eggs with hard shells and the eggs are always laid on land
  7. 7. Characteristics of Each Groups of Vertebrate BIRDSAre only animals with feathers. They have lungs for breathing. All birds come out of an egg with a hard shell.
  8. 8. Characteristics of Each Groups of Vertebrate Are only animals with fur or hair, they also the only animals with mammary glands that gives milk to their young. They give birth to their young. MAMMALS
  9. 9. Warm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature. Warm-Blooded They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment. To generate heat, warm-blooded animals convert the food that they eat into energy. They have to eat a lot of food.
  10. 10. Cold-blooded creatures take on the temperature of their surroundings.. Cold-Blooded Amphibians, reptiles, and fishes They are hot when their environment is hot and cold when their environment is cold. Cold-blooded animals are much more active in warm environments and are very sluggish in cold environments. This is because their muscle activity depends on chemical reactions which run quickly when it is hot and slowly when it is cold. A cold-blooded animal can convert much more of its food into body mass compared with a warm-blooded animal.
  11. 11. Why are crocodile called amphibians? Dolphins a a mammals? Seahorse a fish? TRIVIA crocodiles are reptiles. A Crocodile is a reptile. It does not have webbed feet. Crocodilians are reptiles and share advanced features not seen in amphibians - in particular, they lay shelled eggs on land, not soft eggs in the water.
  12. 12. Why are Dolphins called a mammals? TRIVIA dolphins are mammals, not fish. Mammals, unlike fish, feed their young with milk that is produced in the mother's body. Also unlike fish, dolphins have lungs and are warm-blooded-that is, their body temperature always stays about the same, no matter what the temperature of their surroundings. Many scientists believe that dolphins rank among the most intelligent animals, along with chimpanzees and dogs.
  13. 13. Why are whales called a mammals? TRIVIA Like other mammals, whales give birth to live young and feed them with milk produced by the mother's body. Most fish, however, lay eggs and do not feed their offspring. Whales are also warm-blooded--that is, their body temperature remains about the same regardless of the temperature of their surroundings. Like these mammals, whales have a highly developed brain and are among the most behaviorally complex of all animals. Whale is a huge sea animal that looks much like a fish. But whales are not fish. They belong instead to the group of animals called mammals. Other mammals include chimpanzees, dogs, and human beings.
  14. 14. Why are Seahorse called a fish? TRIVIA While seahorses appear to be very different from other fishes in the sea, they are fish nonetheless. They belong to the same class as all other bony fish such as salmon or tuna. If one stretches a seahorse and lies it stretched out on its stomach, it is easy to see that they really are fish. Because they breath water not air. (a water-dwelling, gill-breathing vertebrate)
  15. 15. Identify the following whether they are mammals, reptiles, birds, fishes, amphibians 1. They live in water, have scales and gills for breathing. 2. They have dry and scaly skin animals that are hatched from eggs with hard shells. 3. They have mammary glands and the only group of animals with group of animals with fur or hair. 4. They have feathers, they have lungs for breathing. 5. Live on water when they are still babies and on land when they grow up REPTILES FISHES MAMMALS BIRDS AMPHIBIANS
