Kingdom Animalia ~ Characteristics ~ Multi-cellular •Eukaryotic with no cell walls • Heterotrophs (consumers) •motile • Characteristics Cont. Animal Movement • Motile, mobile –Most animals are capable of complex and relatively rapid movement compared to plants and other organisms. Animal Reproduction • Most animals reproduce sexually, by differentiated haploid cells (eggs & sperm). • Most animals are diploid, meaning that the cells of adults contain two copies of the genetic material. Characteristics of Life 1. Living things are organized. 2. Living things are made up of cells. 3. Living things metabolize. 4. Living things maintain an internal environment. 5. Living things grow. 6. Living things respond. 7. Living things reproduce. 8. Living things evolve. Animal Sizes • Animals range in size from no more than a few cells to organisms weighing many tons a mesozoan blue whale Animal Habitats • Most animals inhabit the seas, with fewer in fresh water and even fewer on land. Animal Cell Diagram Animal Bodies • The bodies of most animals are made up of cells organized into tissues. • Each tissue is specialized to perform specific functions. Cells->tissues->organs->organ sys >organism Animal Symmetry • Describes how animal body structures are arranged • Allows animals to move in different ways • Cnidarians and echinoderms are radially symmetrical. • Most animals are bilaterally symmetrical. Symmetry: • The most primitive animals are asymmetrical: No symmetry Radial Symmetry • forms that can be divided into similar halves by more than two planes passing through it. • Animals with radial symmetry are usually sessile, free-floating, or weakly swimming. Radial Symmetry Bilateral Symmetry • Animals with bilateral symmetry are most wellsuited for directional movement. Bilateral Symmetry ~Invertebrates~ • No backbones • 95% of all animals are in this group ~ Protection and Support ~ –exoskeleton – a hard, waxy coating on the outside of the body – endoskeleton – support framework within the body ~Invertebrate Phylum Porifera~ • Sponges • simplest form of animal life • live in water • Do not move around • no symmetry • 5000 species ~Invertebrate Phylum Porifera~ • Examples: Tube Sponge, Glass Sponge, Sea Sponge ~Invertebrate Phylum Cnidaria~ • Live in water • Most have tentacles • catch food with stinging cells • gut for digesting ~Invertebrate Phylum Cnidaria~ 2 different shapes Medusa - like a jellyfish Polyp - like a hydra ~Invertebrate Phylum Cnidaria~ • Examples Jellyfish, Hydra, sea anemones, and corals • Soft bodies ~Invertebrate Phylum Mollusca ~ • Hard Shells • Live on land or in water • have a circulatory system and a complex nervous system. • Important food source for humans ~Invertebrate Phylum Mollusca ~ Class Gastropoda –snails and slugs –may have 1 shell –stomach-footed move on stomach ~Invertebrate Phylum Mollusca ~ Class Bivalves –2 shells hinged together –clams, oysters, scallops and mussels ~Invertebrate Phylum Mollusca ~ Class Cephalopods –squids and octopuses –internal mantel ~Invertebrate Phylum Platyhelminthes: worms ~ Flatworms Example: Planaria, tape worms Flat, ribbon-like body Live in water or are parasites lives in intestines of host absorbing food bilateral symmetry Regeneration- regrow body parts ~Invertebrate : Flat WORMS Cont.~ eyespots detect light scavengers & predators lives in intestines of host absorbing food food and waste go in and out the same opening Examples of flat worms ~Invertebrate Phylum Annelida ~ Are Segmented worms Have Body divided into segments (sections) –Live in water or underground –have a nervous and circulatory system ~Invertebrate Annelida Cont~ • Earthworms • eat soil and breakdown organic matter, wastes provide nutrients to soil More annelids: segmented worms • leeches • parasites that feed on blood of other animals ~Invertebrate Phylum Arthropod ~ • Body divided into sections/segments • Exoskeleton – outer – Molt – shed exoskeletons as they grow • Jointed appendages (legs) • well developed nervous system • largest group of organisms on earth ~Invertebrate Phylum Arthropod ~ • Include the classes: –Crustaceans, arachnids, centipedes, millipedes, and ***Class insecta • Classified into classes according to the number of legs, eyes and antennae they have. ~Invertebrate Phylum Arthropods~ • Insects- 3 body sections 1. Head – antenna 2. Thorax – midsection (wings and legs) 3. Abdomen – (internal organs/structures) – grasshoppers, ants, butterflies, bees ~ Phylum Chordata: Vertebrata~ 5 classes • Fish • Mammals • Reptiles • Amphibians • Birds Fish • Are cold-blooded • Have gills and scales • Live in water • Have a Backbone These are Fish: Fish have Backbones Reptiles: • Have scales • Live on land • Are cold-blooded • Usually lay eggs • Have a Backbone These are Reptiles Crush!!! Reptiles have Backbones Amphibians •Lay eggs •Live in water and on land •Have a Backbone •Are cold blooded •Have smooth skin These are Amphibians • These are Amphibians Amphibians have Backbones Birds • Have feathers • Are warm-blooded • Have hollow bones and most can fly • Lay eggs • Have a Backbone These are Birds Birds have Backbones Mammals • • • • Have hair or fur Are warm-blooded Feed milk to their young Bear live young (except monotremes) • Have a Backbone These are Mammals Mammals have Backbones • • • • • • • • • • • • • • • • • • • • • • Clip Art Photos http://clipartuniverse.com/free-animation.shtml black widow, vulture, girl and horse, frog http://www.infohub.com/ARTICLES/platypus.html platypus http://www.herper.com/Waterspider.html water spider http://www.liveaquaria.com/ starfish http://www.discoveryschools.com.au/guides/invertab/overview.html jellyfish bmp http://www.cockroaches.sf.cz/ roach http://www.antcontrols.com/carpenter1.jpg carpenter ant http://www.kwic.com/~pagodavista/schoolhouse/species/herps/turtle.htm turtle skeleton http://encarta.msn.com/find/MediaMax.asp?pg=3&ti=761552814&idx=461518272 fish skeleton, http://www.zoology.ubc.ca/courses/bio204/lab7_photos.htm frog, lizard, bird, rat, and porpoise skeletons http://dgl.microsoft.com/?CAG=1 clips http://members.aol.com/loxocemus/snakepics/nonamer.jpg garter snake http://www.versaquatics.com/angelfish.htm fish photo, crab, nudibranch, sea turtle, http://www.montereybaywhalewatch.com/phharbp.htm porpoise photo http://museum.gov.ns.ca/mnh/nature/turtles/paint.htm painted turtle http://artsci.wustl.edu/~reglor/salgall/myon2.jpg salamander http://radical-reptiles.herpetology.com/lizardgallery/collared4.jpg collard lizard http://www.cmycat.com/greatoutdoors.htm cat photo http://www.cat.cc.md.us/courses/bio141/lecguide/unit1/shape/dkngon.html coccus bacteria http://www.smithton.tco.asn.au/wildlife/lobster/lobster.html alligator skeleton • • • • • • • • • • • Photos continued http://saltaquarium.about.com/gi/dynamic/offsite.htm?site=http%3A%2F%2Fww w.harboraquatics.com%2Fsponge01.html spongeshttp://www.underwatercolours.com/bvi/ss5.html -Anemone http://www.meer.org/M31.htm platyhelminthes http://users.htcomp.net/weis/worms.html -earthworm http://www.smithton.tco.asn.au/wildlife/lobster/lobster.html lobster http://www.mermaid1.demon.co.uk/body_molluscs.htm snail, limpet, cuttlefish http://www.mermaid1.demon.co.uk/body_worms.htm - fanworm http://www.versaquatics.com/octopus_photos.htm octopus http://www.mermaid1.demon.co.uk/body_echinoderms.htm urchin, starfish http://www.dudak.baka.com/is373.html grasshopper on goldenrod Back to Start
