Kingdom Animalia Characteristics
|
-multicellular
-heterotrophic organisms -eukaryotic cells -greatest diversity: invertebrates vs vertebrates -use locomotion to find food |
|
|
Invertebrates
|
animals without backbones
|
|
|
Phylum Porifera (least complex)
|
-contains sponges
-no mouth BUT have pores that draw in H20 for their cells to filter + absorb food -2 cell layers -live in h20 -have radial symmetry -sessile= not able to move |
|
|
Phylum Cnidaria
|
-coelenterates
-mouth (opening for ingestion) -2 cell layers -hollow body cavity for digestion -stinging cells (nematocysts) -tentacles -motile i.e. hydra, jellyfish, coral & sea anemone |
|
|
Phylum Platyhelminthes
|
-flatworms
-bilateral symmetry -i.e. planaria & tapeworms |
|
|
Phylum Nematoda
|
-roundworms
-bilateral symmetry -parasitic -i.e. Trichinella (pork worm), hookworm, ascaris |
|
|
Phylum Annelida
|
-segmented worms
-tube-within-a-tube body organization -bilateral symmetry -i.e. sandworm, leech, earthworm |
|
|
Phylum Mollusca
|
-mollusks
-soft bodies & hard shell -i.e. snails, clams, oysters, octopi |
|
|
Phylum Arthropoda
|
-organisms with jointed appendages
-exoskeleton (outside skeleton made of chitin) 3 classes: Crustacea, Arachnida & Insecta |
|
|
Crustaceans
|
-class of Phylum Arthropoda
-live in marine or fresh water -2 body parts: cephalothorax: head/thorax combined abdomen -gills for breathing -antennae -appendages used for locomotion, food gathering, & eating -i.e. shrimp lobsters & crabs |
|
|
Arachnids
|
-class of phylum arthropoda
-2 body parts: cephalothorax abdomen -8 legs -no wings i.e. spiders, scorpions, ticks |
|
|
Insects
|
-3 body parts:
head, thorax, abdomen -3 pairs of legs -most have 2 pairs of wings -ability to perform metamorphosis (change in body form from young to adult) -largest number of species in the animal kingdom -i.e flies, mosquitos, moths, ants, grasshoppers |
|
|
Phylum Echinodermata
|
-spiny-skinned organisms
-live in marine water -radial symmetry -i.e starfish, sea urchins |
|
|
bilateral symmetry
|
the right and left sides of the organism are similar
|
|
|
How is respiration in a crustacean different from respiration in an insect?
|
Crustaceans use gills for breathing and insects use tracheal tubes
|
|
|
Vertebrates
|
animals with backbones
|
|
|
Phylum Chordata
|
-have a dorsal (back) notochord (backbone) which is a flexible rod-like structure found at some time in their embryonic development
|
|
|
Osteichthyes
|
-class of phylum chordata (least complex)
-bony fishes -live in marine or fresh water -have gills -scales -fins -two-chambered heart -cold blooded (body temp=environment) -i.e. tuna, flounder, trout, bass, salmon, goldfish |
|
|
Amphibia
|
-class of phylum chordata
-can live on water or land -most have ability of metamorphosis -young have gills -adults have lungs -3 chambered heart -cold blooded -i.e. frogs, salamanders, newts |
|
|
Reptilla
|
-class of phylum chordata
-land animals with lungs for breathing -scales -4 chambered heart -cold blooded i.e. snakes, lizards, turtles, alligators & dinosaurs |
|
|
Aves
|
-class of phylum chordata
-birds -feathers -wings -beaks -hollow bones for flying -scales on their legs -4 chambered heart -warm blooded -i.e. sparrows, owls, pigeons, penguins |
|
|
Mammalia
|
-class of phylum chordata
-mammary glands to feed milk to their young -body hair -four chambered heart warm blooded -i.e. humans, dolphins, pigs, whales, bats and polar bears |
