INVERTEBRATES
Invertebrates ? Animals without backbones ? 97% of all animal species
Invertebrates Phylum Annelida Phylum Porifera Phylum Molluska Phylum Cnidaria Phylum Echinodermata Phylum Platyhelminthes Phylum Arthropoda Phylum Nematoda
PHYLUM PORIFERA (Sponges) ? ¡°Porifera¡± means pore ¨C bearing ? lacks true tissues & organs; incomplete digestive system ? has skeleton that supports & protects the body; made up of ¡°spicules¡±
Invertebrates_Edtech101
PHYLUM CNIDARIA ? Radially symmetric ? digestive chambers with a single opening, which serves as both mouth & anus ? Includes: hydras, jellyfish, corals and sea anemones
PHYLUM CNIDARIA 2 body forms: polyp form and medusa form 1. polyp form - cylindrical; mouth & tentacles at the upper end 2. medusa form ¨C shaped like an upside-down bowl; mouth & tentacles facing downward has tentacles with stinging cells called ¡°cnidocytes¡± that paralyzes their preys Jellyfish -medusa Coral - polyp
Sea anemones Jellyfish Coral Hydra
PHYLUM PLATYHELMINTHES (Flatworms) ? with flattened bodies; bilateral symmetry ? lacks body cavity ? most flatworms are parasites
PHYLUM PLATYHELMINTHES (Flatworms) ? 3 major groups: flukes, planaria & tapeworms 1. Flukes ¨C parasites that absorb the nutrients from the body of a host harming it; causes a disease called schistosomiasis 2. Planarians ¨C non-parasitic, lives in moist environments & free-living 3. Tapeworms ¨C long ribbon-like flatworm; can infect humans through eating undercooked meat of an infected cow or pig
Fluke Planaria Tapeworm
PHYLUM NEMATODA (Roundworms) ? has cylindrical bodies tapered at both ends & covered by a tough cuticle ? includes parasitic types: trichina, filaria, pinworms, & hookworms ? Many are introduced through poorly cooked pork or walking barefoot in contaminated areas. ? Some diseases caused by roundworms: elephantiasis, trichinosis.
Pinworm Filaria Hookworms Trichina
PHYLUM ANNELIDA (Segmented Worms) ? With segmented bodies which has a ringed appearance ? Includes: earthworms & leeches
PHYLUM MOLLUSKA (Mollusks) ? Second largest animal phylum ? Includes: oyster, clams, snails, squids and octopuses ? Some are sources of food for humans.
Oysters Clams
Snail Squid Octopus
PHYLUM ECHINODERMATA (Spiny-skinned) ? Includes: starfish, sea urchin and sea cucumbers ? Has internal skeleton for support & protection
Starfishes Sea cucumber Sea urchins
PHYLUM ARTHROPODA (Arthropods) ? Largest group in the animal kingdom ? Has exoskeleton; segmented body & joint appendages ? Divided into 4 groups: 1. Crustaceans ¨C lobsters, shrimps, crabs & crayfish 2. Insects ¨C ants, mosquitoes, bees, wasps, bugs & flies 3. Arachnids ¨C spiders, mites & scorpions 4. Myriapods ¨C centipedes & millipedes
