Vertebrates

Vertebrates

1. Vital functions

   • Nutrition
     • Carnivore
     • Hervivore
     • Omnivore
   • Interaction
   • Reproduction
     • Sexual
     • Asexsual

2. Symmetry

   • Bilateral
   • Radial
   • Asimmetry

3. Fish

   • Strong muscles, smoth body cover with scales, fins limbs. Ectogermic, oviparous, most carnivores.

4. Amphibians

   • Tetrapods, thin moist skin, cool-blooded, breathe through their skin.

5. Reptiles

   • Most terrestrial, tough and dry skin, have scales made of keratin, tetrapods, ectothermic, breathe through lungs, oviparous, many carnivores.

6. Birds

   • Have strong beak and wings, body cover of feathers, endothemic, breathe though lungs, varied eating habits, amniotic eggs, oviparous.

7. Mammals

   • Most terrestrial, have different types of glands, tetrapods, endothemic, breathe through lungs, viviparous, have very developed nervous system.
     • Marsupials: they are viviparous, but haven't got a developed placenta, so the young stay some months in the mother's pouch.
     • Monotremes: they are the only mammals that are oviparous.
   • Humans beings are vertebrate and placental mammals. We have particular caracteristics: We have little hair, female develop mammary glands, our skin has sweat glands, we are bipeds, we communicate, recive information and learn.

8. Acuatic vertebrates

   • The bodies are adapted to move trough water. Their limbs, if they have, are short and close to the trunk.

9. Terrestrial vertebrates

   • Runners: long slim limbs, developed muscles.
   • Jumpers: back legs long and strong.
   • Climbers: hands adapted to graspring. Light bodies, long tail.
   • Flyers: front limbs are wings. Aerodynamic bodies help them fly.
