|
Animalia |
monophyletic (share common ancestor), sexual reproduction, chemoorganoheterotrophs, multicellular, eukaryotes, no cell walls, diploid dominate, locomotion, nerve and muscle cells (except sponges) |
|
|
parthenogenesis |
virgin birth |
|

phagotrophs |
ingest food, DO NOT ABSORB IT ACROSS EXTERNAL TISSUES |
|
|
characteristics |
1. Does animal have complex tissues, or generalized tissues 2. Type of body symmetry: bilateral or radial 3. form of body cavity: diploblastic & triploblastic 4. type of embryological development :protostomes or deuterostomes 5. segmentation |
|
|
lack complex tissues (generalized) |

|
|
complex tissue |
everything but ph placzoa |
|
|
radial symmetry who? |
no front or back, no right or left jellyfish, sea anemones, coral, cone jelly |
|
|
bilateral |
have front/back, have right/left, every other animal |
|
|
diploblastic |
possess ectoderm(skin, nervous system)/endoderm(lining of digestive tract), radial symmetry, |
|
|
triploblastic |
ectoderm, mesoderm, endoderm |
|
|
Protostomes |
mouth to anus new cells form at an angle off of old cells determinate devo |
|
|
deuterostomes |
anus to mouth Ph. Chordata and Ph. Echinodermata indeterminate devo cell fate is determined much later in devo (stem cells) |
|
|
segmented animals |
Ph Annelida Ph Arthropoda Ph Chordata Ph Onuchophora Ph Kinorhyncha Ph Tardigrade Increase complexity of movement, integration of muscles/skeletal system, organ redundancy |
|
|
Ph Porifera |
Sponges lack specialized cells, filter feeders, use choanocytes which whip flagella to draw water in w nutrients, rigid structure(spongin), sessile (non-moving) |
|
|

|
|
hermaphrodites |
can fertilize self |
|
|
glochidia, chitons, gastropoda, hermaphrodites, nudibranchs, cephalopods |
Ph Mollusa |
|
|
cl glochidia |
attach to fish and other animals as parasites on blood once developed, drop off and develop into adult |
|
|
cl chitons |
marine environments, use radula (biofilm) |
|
|
cl gastropoda |
snails, slugs, nudibranchs, predators, herbivores, detritivores |
|
|
cl hermaphrodites |
common, same individual w viable eggs/sperm, alternately inseminate each other (not self fertilization) |
|
|
cl nudibranchs |
sea slug, marine, herbivores, predators, accumulate toxins/chloroplasts/nematocysts from cnidarians |
|
|
cl cephalopods |

coelomate, protostomes, bilateral, segmented, freshwater, marine, terrestrial, earthworm, leeches, polychaete, bristle worms, tube worms |
|
|
cl polychaeta |
many hairs/setae predators, detritivores, herbivores, can handle extreme conditions, tube worms (deep ocean, hydrothermal vents, mutualism w bacteria- provide E nutrients for growth/reproduction for tube worm and feces for bacteria) |
|
|
Cl Clitellata |
few hairs, earthworms, leeches, freshwater, terrestrial, hermaphrodites (exchange sperm during mating) |
|
|
