    Vertebrates vs invertebrates Vertebrates vs invertebrates Presentation Transcript

    • Vertebrates vs Invertebrates
      By Brian Roby
    • Getting the obvious out there…
      The major difference between vertebrates and invertebrates is that vertebrates have a backbone and invertebrates do not.
    • Categories of Animals
      All vertebrates are under the classification “Chordates”
      This is the only group that includes vertebrates
      Humans are classified under this group
    • Different Types of Vertebrates
      Vertebrates are broken down into 5 different types
    • Fish
      Fish are categorized into 3 different types: Cartilginous(Including sharks and rays), Ray-finned(Salmon all the way to goldfish), and Lobe-finned(Lungfish and coelacanths)
    • Mammals
      Mammals are grouped into 3 different categories: Monotremes (Platypuses), Marsupials (Kangaroos, koalas, wallabies, and possums), and Placental Mammals (Primates and Humans!)
    • Reptiles
      The reptile group is very diverse and differs greatly from most of vertebrates because it is a ectothermal animal meaning that it must get it’s body heat from the sun and shade
      The Reptile group includes animals such as snakes, lizards, crocodiles, alligators, and turtles.
    • Amphibians
      Amphibians live a very odd life. They actually change they’re form as they develop. They start as eggs and then transform into a fish life creature only to end up as a tetra pod (4 footed animal)
      Amphibians include animals such as frogs, toads, and salamanders
    • Birds
      Birds are covered in feathers which enable them to fly making them one of the few vertebrates to be able to fly
      Birds have over 9,700 species!!!!
    • Different Types of Invertebrates
      Invertebrates are broken down into 8 different categories
      Again, invertebrates are any animal without a backbone
    • Sponges
      Sponges have no tissues or organs in their body
      They’re filter feeders, meaning that they pump water through their pores to feed
      There are 5,000 species of sponges!
    • Cnidarians
      Cnidarians are a very diverse group, this group includes jellyfish, sea anemones and coral.
      These animals are incredibly dangerous to humans sometimes.
      Some cnidarians, such as the Box Jellyfish, can kill a human with one simple sting.
    • Flatworms
      Flatworms include parasites which can harm humans and sometimes kill them
      Flatworms include Tapeworms and Flukes
    • Roundworms
      Roundworms are found all over earth, including salt and fresh water!
      There are over 90,000 species of roundworms, though the number is believed to be much higher
      The most known species is of course the earthworm, which can be found anywhere dirt is
    • Molluscs
      Molluscs have three different types, Gastropods (Snails and slugs), Bivalve molluscus( Clams, scallops, and oysters) and Cephalopods(Octopuses and squids).
      Most molluscs spend their lives living in a shell
      There are over 43,700 species of molluscs
    • Arthropods
      Arthropods have 4 different groups that include Insects (Bee’s and flies), Arachnids (Spiders), Crustaceans (Crabs and Lobster), and Millipedes and centipedes
      The lack of a backbone for this animal does not affect it at all because of the tough exoskeleton that is around all Arthropods
    • Echinoderms
      This class includes Sea Stars, Sea Urchins, and Sea cucumbers
      This group is the closest related to Humans because of every member of the Echinoderms has radial symmetry just like humans do!!
