Subkingdom Parazoa Phylum Proferifera Animals that posses neither tissues nor organs Click here for : List

Phylum Proferifera Aquatic Lack tissues and organs Motile larvae Sessile adults Filter feeders Skeleton made up of spongina and/or spicules Dead end phylum Examples: Venus’ Flower Basket, Bath Sponge, Tube Sponge Back

Phylum Echinodermata Subkingdom Metazoa Phylum Chordata Phylum Anthropoda Phylum Annelida Phylum Mollusca Phylum Nematoda Phylum Platyhelminthes Phylum Cnidaria Click for: List

Phylum Cnidaria Either a Medusa shape, like jelly fish, or a polyp, like coral Still very simple filter feeders Open circulatory system, No brain. Oxygen comes from the water around them. Kill prey with toxins that paralyze the body Back Classes: Hydrozoa: Hydras, both polyp and medusa Scyphozoa: Jellyfish, medusa Anthozoa: Polyps, sexual & asexual Click for movie

Phylum Platyhelminthes Flatworms Some are parasites Some are free living Single opening system Circulatory and respiratory systems not developed Can enter sponges or Cindarians Cephalization Back Beef tapeworm Classes Turbellaria: Free living, flat worms Trematoda: External & internal parasites, flatworms Cestadoa:Tapeworms, have a head

Phylum Nematoda §Round worms §Don’t have a brain §Two opening system: Mouth and Anus §Reproduce sexually §Breath through body walls §Do not positively affect humans §Bilateral symmetry Back Tail of a hookworm

Phylum Mollusca Soft bodies with internal or external shell Four basic parts: Foot, mantle, shell, visceral mass External fertilization Excrete through an organ called the nephridia Very intelligent Use gills for breathing Solid waste Back Classes Plecypoda- Bivalves, open circulatory Gastropoda- Gastropods, some terrestrial Cephalopoda- Closed circulatory Click for movie

Phylum Annelida Round Worm-like animals Segmented Two opening digestive system Closed circulatory system Variety of colors Bilateral symmetry Ventral nerve cord down center of body Back Leech Classes Polycheata: Marine worms, long bristles Oligochaeta: Earthworms, few bristles Hirudinea: Leeches, carnivorous, parasitic

Phylum Anthropoda Tough exoskelton Jointed appendages Open circulatory system Well-developed brain Segmented body BackSubphylums Chelicerate: Two-part body, chelicerea Crustacea: Hard exoskeleton, two pair antenna, mandibles Uniramia: One pair antenna, unbranched appendages Uniramia Classes Chilopoda: Carnivorus with posin claws, long worm-like body, lots of legs Diplopoda: Worm like body, lots of legs, not carnivorus Insecta: Body has three parts and three pairs of legs, mandibles, societies Click for movie

Phylum Chordata Notochord, sometimes replaced with a backbone Pharyngeal gills during some part of development Hallow dorsal nerve cord Closed circulatory system Two sets of paired appendages (limbs) Back Fishes Amphibians Reptiles Birds Mammals

Fishes Two chambered heart Scales and fins Pharyngeal gills Excretion through gills Respiration through gills and swim bladder Advanced nervous system Lay eggs Classes Cephalaspidomorphi: Larve are filter feeders and adults are parasites Chondrichthyes: Bony endoskeleton Osteichthyes: Live in salt water, endoskeleton of cartlage Back

Amphibians Adapted primarily to life in wet places Ectothermic Most are carnivorus Moist, smooth skin Lay eggs Internal fertilization Adults either aquatic or terresterial Back Orders Urodela:Salamanders Anura: Frogs and toads Apoda: Legless amphibians Click for movie

Reptiles Adapted to terresterial life More advanced then amphibians Dry, scaled skin Amniotic eggs has a hard outer shell Three to four chambered heart Back Orders Squamata: Lizards and snakes Crocodilia: Crocodilians Chelonia: Turtles Click for movie

Birds Endothermic-first Feathers cover body surface Scales on legs and feet Hollow bones Four chambered heart Well developed lungs and air sacs Internal fertilization Back Class Aves Click for movie

Mammals Most viviparous Many have sweat glands Mammary glands Hair Four chambered heart Back Orders Monotremata: Lay eggs that hatch externally Marsupaila: Pouched animals Insectavora: Feed on anthropods Primates: Highly developed brain, complex social interaction Carnivora: Live in salt water or on land Perissodactyla: Odd-toed ungulates Artiodactyla: Even-toed ungulates Click for movie
