  1. BIODIVERSITY PROJECT Mike Cathcart, Jake Boudreau, and Gio Holmes

  2. Kingdom: Vertebrates Principal Characteristics • Bilateral symmetry • Body segmentation • Endoskeleton (bony or cartilaginous) • Pharyngeal pouches (present during some stage of development) • Complete digestive system • Ventral heart • Closed blood system • Tail (at some stage of development)

  3. Method of Reproduction • All vertebrates reproduce sexually, the males reproductive cell, the sperm meets with the female reproductive cell, the egg through sexual intercourse. Habitat • Vertebrates live in all areas of the world, it is hard to pin point an exact area of their location because they are everywhere. A vertebrates habitat is anywhere that there is oxygen.

  4. Life Cycle of a Grizzly Bear • Grizzly Bears mate in the spring time. • When winter comes around they hibernate. • Bears usually give birth towards the end of hibernation and can give birth to more than one cub. • Once the cub is about a year old, it is almost fully grown. • After 2-3 years the cub is forced to leave by its mother and is ready to support itself. • Grizzly Bears are ready to mate at the ages of 4-7 • They can live up to 30 years.

  5. Corporal Structure • Vertebrates have bilateral symmetry, meaning that if you cut them in half vertically they would be the same or similar on both halves. • Vertebrates have cells, tissues, organs, and systems. • Vertebrates are multi-cellular, meaning that they are made up of more than one cell. • Vertebrates are eukaryotes, because they have a true nucleus in every cell.

  7. Food/Digestion • All vertebrates are heterotrophs, meaning that they can’t make their own food. • They eat by consuming food and then digesting it. • They digest their food by using their digestive system, containing the mouth, the esophagus, stomach, liver, gall bladder, pancreas, small intestine, and the large intestine.

  8. Circulation • Vertebrates have a closed circulation meaning that the blood is closed at all times within vessels • Blood is pumped by a heart through vessels • A closed circulation does not normally fill body cavities. Respiration • Vertebrates use aerobic respiration. • They bring oxygen into their lungs, through their mouths and nose and then produce waste known as carbon dioxide (CO2)

  9. Nervous System • Vertebrates have a brain and nerves. • You can tell that they responded to external stimuli because if you went up and poked a bear, they would respond to your poke.

  10. Vertebrate Kingdom Kingdom – Animalia Phylum – Chordata Classes - Class Ascidiacea(sea squirts) Class Thaliacea (salps) Class Appendicularia (larvaceans) Class Sorberacea Class 'Agnatha'paraphyletic (jawless vertebrates) Class Placodermi (Paleozoic armoured forms) Class Chondrichthyes (cartilaginous fish; 900+ species) Class Acanthodii (Paleozoic "spiny sharks") Class Osteichthyes (bony fish; 30,000+ species) Class Amphibia (amphibians; 6,000 species) Class Reptilia (reptiles; 8,225+ species) Class Aves (birds; 8,800–10,000 species) Class Synapsida (mammal-like "reptiles"; 4,500+ species, progenitors of mammals) Class Mammalia (mammals; 5,800 species) Class Leptocardii (lancelets)

  11. Interesting Facts About Vertebrates • 1: Vertebrates are some of the smartest species on earth. • 2: There are five classes of vertebrates fish, amphibians, reptiles, birds, and mammals. • 3: About 58,000 species of vertebrates have been currently described.
