Cnidaria AnemonesJellyfish Coral Radial symmetry,Hydrostatic skeleton, Dimorphic development Can sting!
Anemones Marine Need excellent water condition Most capture animal prey; zooanthellae Variable but specific temperature requirements dependent upon species Asexual reproduction Interspecific Aggression
Jellyfish Marine Water flow patterns Predators – have stingers! Sexual reproduction Lots of species variability
Coral Marine Water Quality Important! Zooxanthellae; Most capture animal prey Sexual & Asexual Reproduction Can exhibit contact inhibition and interspecific aggression in the tank Hermatypic vs Ahermatypic
Echinoderms Marine Water quality important- toxicity problems Diet is largely dependent on species Asexual & sexual reproduction dependent on species Water vascular system locomotion, gripping, feeding http://www.studentreader.com/files/purplestarfishonrocks.jpg
Sea Squirts Sessile, marine Environmental management based on species Herbivorous diet Sexual or Asexual reproduction 90% of all urochordates http://www.lancashiremcs.org.uk/gallery/pics/sea-squirt.jpg
Annelids Aquatic and terrestrial Varied diet and feeding strategies Environmental requirements dependent upon species Sexual reproduction; dioecious Biomedical & ecological importance http://www.education.umd.edu/blt/pic/Annelids.jpg
Myriapods Terrestrial Diet dependent on species Well defined environmental requirements Dieocious; some parthenogenic
Myriapods Millipedes Mostly herbivorous Two pairs per body segment Non-aggressive; slow Easy to handle Centipedes Mostly carnivorous One pair of legs per body segment Aggressive; fast! Extremely hard to handle; venomous http://www.garden-city.org/zoo/animalinfo/images/milipede_76pic.jpg http://cordially.narod.ru/album/insect/images/home-centipede.jpg
Millipedes Substrate: 8-10cm of soil with 3-4cm of leaf litter on top Temperature Humidity Diet: leaf litter, fruits & vegetables Reproduction
Centipedes Soil covered with leaf litter or mulch Temperature Humidity Light Diet: mix of live and dead invertebrates, dead pinky mice, day old chicks, adult mice, etc. Reproduction
