Kingdom Animalia Characteristics • • • Heterotrophs Eukaryotic Multicellular No cell wall, no chloroplasts Motile Sense Organs
9 phyla we will mention • • • Porifera—sponges Cnidaria—jellyfish, sea anemones, coral Platyhelminthes—flatworms Nematoda—roundworms Annelida—earthworms Mollusca—shelled animals Arthropoda—insects, spiders Echinodermata—spiny-skinned Chordata—vertebrates (and others)
Phylum Porifera (sponges) • • Asymmetrical Pores—filter feeders Not motile (sessile) Provide habitat for other animals • Eaten by starfish and some fish • Most primitive animal
Phylum Cnidaria (jellyfish, sea anemones, coral) • Digestive cavity called a coelenteron • Radial symmetry • Predators-feed on crustaceans • Corals provide important habitat for fish • Coral used for decoration and threatened by pollution • All have stinging cells
Phylum Platyhelminthes (planarians, tapeworms, flukes) • Bilateral symmetry • Cephalization- head and brain • Acoelomate- no body cavity • Incomplete digestive system (one opening) • Some are parasites in digestive tract • In early 1900’s models ate them to be thin— YUK!
Phylum Nematoda (roundworms) • Also called nematodes • Complete digestive system-separate mouth and anus (2 openings) • Pseudocoelomate • Decomposers, predators (bacteria, inverts) • Eaten by insects, mice • Beneficial to garden by eating insects
Phylum Annelida (segmented worms) • i. e. earthworms, leeches • True coelom • Sensitive to vibrations on ground-rain • Prey for robins, shrews, jays, snakes • Leeches have cornified knobs to break skin, anticoagulant and anesthetic
Phylum Mollusca (shelled…sometimes) • i. e. snails, slugs, clams, mussels, scallops, oysters, octopus and squid • Variety in form • Giant squid = sea serpent • Introduction of garden snails
Phylum Arthropoda (jointed legged animals) • i. e. insects, spiders and scorpions, shellfish (crustaceans), centipedes (1 pr legs per segment), millipedes (2 pr) • Exoskeleton • Metamorphosis • Pheromones • Molting
Phylum Echinodermata (spiny-skinned) • i. e. sea stars = starfish, sea urchins • Water vascular system • Tube feet • Important predators
Phylum Chordata (includes the vertebrates) • i. e. fish, sharks, amphibians, reptiles, birds, mammals • Notochord, nerve cord, gill slits, tail
