Kingdom Animalia Invertebrates

Cell Type/ Description  Multicellular  Nucleus  Cell Organelles

Food  All Ingest Food  Animals must eat others for energy

Movement  Muscles

Reproduction  Asexual—one parent  Sexual—two parents

Examples  Sponges  Worms  Mollusks  Insects  Starfish

 Animals have specialized parts- skin, tissues, organs  Mobile- they move during some phase of their life  Consumers- heterotrophs What does it mean to be an animal?

Invertebrates  Animals without a backbone  The majority of the animal kingdom  Insects, snails, jellyfish, and worms

Body Plans  Bilateral symmetry- body has 2 similar halves- ex: butterfly  Radial symmetry- body is arranged in a circle- ex: sea anemone  Asymmetry- no symmetry – ex: sponges

Phylum Porifera - sponges

 Body Plan  Asymmetrical  No head: No guts  Regenerate- replace body parts

Phylum Cnidaria- jellyfish

Jellyfish Radial symmetry Gut- digestion Nervous system

Phylum Plathyhelminthes- flatworms

Flatworms  Bilateral symmetry  Head  Eyespots  Mostly parasites

Phylum Nematoda- roundworms

Roundworms  Bilateral symmetry  Long and slender  Most are parasites  Infect humans- pinworms and hookworms

Phylum Annelida- segmented worms

Segmented Worms  Body has segments  More complex than flatworms  Circulatory system, nervous system and digestive system  Earthworms

Phylum Mollusca- mollusks

Mollusks  Snails, slugs,clams,oysters, squid, octopuses.  2 nd largest phylum of animals  All have a Mantle- tissue layer over the body

Phylum Echinodermata- echinoderms

Echinoderms  “Echino”= spiny “derm”= skin  Marine animals  Sea stars, sea urchins, sea cucumbers, brittle stars, sand dollars  scavengers/ feed on fish and clams

Phylum Arthropoda- arthropods

Arthropods  Insects, spiders, crabs, and centipedes  Largest group of animals  Exoskeleton- made of chitin  Insects- metamorphosis

Arthropods  Characteristics  Jointed legs  Segmented- head, throax, abdomen  Specialized parts- wings, antennae, gills, claws
