  1. VERTEBRATES Marcel S. Alejandro O. Sergio H. Javier C.

  2. Backbones: The spinalcolummn • Scales: Flat plates covering the body of some animals like some Reptilians and some Fish • Exoskeleton: The external covering structure of animals (shell) • Endoskeleton: Internal skeleton of a body of a animal KEY WORDS

  3. Vertebrates are Animals that have backbone. • They can be Mammals, Birds, Reptiles, Amphibians and Fish DEFINITION

  4. Comparison

  5. Only 5% percent of Animals on Earth • They are the most known and studied • They have muscles and all the organs and systems (NervousSystem, DigestiveSystem, RespiratorySystem. Etc. • Distinguished by having endoskeletonsthatallow more flexibility than exoskeletons (invertebrates). • Bonesprotectorgans (skull, ribs). • Most Vertebrates are Fish IMPORTANT DETAILS

  6. FISH Kingdom: Animalia Phylum: Chordata (unranked) Craniata

  7. Are the most diversegroup • More than 20,000 species • Live in almost every aquatic enviroment • Getoxygen from water using gills that are made of from tissue

  8. -JawlessFish No jaw but teeth Can’t chew Sucks the prey’s flesh and fluids -Cartilagineus Fish Skeletons made of cartilage Some are dangerous to Humans Feed Primarly on Mollusks Some examples are Sharks and Rays -Bony Fish Covered by scales 96% of Fish are Bony Bright colors

  9. Kingdom: Animalia • Phylum: Chordata • Clade: Amniota • Class: Reptilia REPTILES

  10. Originated 320 million years ago • It is said they evolved from being amphibians because they adapted more to land-life • Cold-Blooded • Crocodiles are more related to birds than to lizards • Birds are not considered reptilians because they are warm-blooded. • Dinosaurs were reptiles Details

  11. Testudines (turtles, terrapins and tortoises): approximately 330 species • Sphenodontia (tuataras from New Zealand): two species • Squamata (lizards, snakes, and worm lizards): over 9,000 species • Crocodilia (crocodiles, gavials, caimans, and alligators): 25 species Subgroups

  12. MAMMALS Kingdom: Animalia Phylum: Chordata Superclass: Tetrapoda Clade: Amniota Clade: Mammaliaformes Class: Mammalia

  13. Give Birth • Most have fur • Feed the young with milk of the mammary glands • Warm-blooded • Include the most intelligent species • Most are four-legged Details

  14. Appeared due to the Premian-Triassic Extintion because now carnivores lost their dominance • 210 million years ago *too many subgroups they wouldn’t fit here Details

  15. AMPHIBIANS Kingdom: Animalia Phylum: Chordata Superclass: Tetrapoda Class: Amphibia

  16. Can breathe eitherwith: lungs, skin, gills • Most start as a larva living in water • Some species like frogs and salamanders dont have lungs or gills and rely upon skin • Most of species, the young they use gills and later develop lungs • Require water enviroments to breed Details

  17. Appeard for the first time 370 million years ago • Order Anura (frogs and toads): Jurassic to present—5,602 current species in 48 families • Order Caudata or Urodela (salamanders, newts): Jurassic to present—571 current species in 10 families • Order Gymnophiona or Apoda (caecilians): Jurassic to present—190 current species in 10 families Subgroups and history

  18. BIRDS Kingdom: Animalia Phylum: Chordata Clade: Avialae Class: Aves

  19. Around 10,000 species • Habit almost every enviroment across the globe • Moder birds are characterised by having feathers and a beak with no teeth • Lay eggs • Many species overtake migrations due to weather Details

  20. Appeared 160 million years ago • Most are diurnal • Some like Owl and Nightjars are nocturnal Details
