a desingned dichotomous key for terrestrial invertebrates
130994
First you need to know what phyla of invertebrates you will include. Then, get at least a picture that represents each one, and start by separating them into large categories using a visible feature. Then separate each of the major groups into smaller ones. \nRepeat this, and write down each step of this process. Then order your notes and add numbers to go from one alternative to the next... voilà the dichotomous key.\n\n\n\nAlternatively, if you want a ready-made one, try these resources:\nhttp://www.msc.ucla.edu/oceanglobe/pdf/Invertebrates/Inverts_Key_Phyla.pdf\nhttp://www.bio.davidson.edu/courses/invertzool/lab/ex1taxonomy.pdf\n\nIf you do it yourself it's more fun :-)

kingdom = animal\nphylum = arthropoda\nclass = Malacostraca\norder = Decapoda\nfamily = Nephropidae (clawed) or Palinuridae (spiny) or Scyllaridae\ngenus = Enoplometopus (the only one I could find)\nspecies = lobster

One website that I like is called Tree of Life\nhttp://tolweb.org/tree/phylogeny.html\n\nit is a realitively straight forward scheme that allows you to pick the picture of the goup and then to pick subdivisions below that to classify your organism down to the Class level.\n\nand many other resources can be found from:\nhttp://www.biology.ualberta.ca/courses.hp/zool250/links.htm\n\n\n\nTo distinguish a chordate it must have the following 4 traits embryologically:\n - a notocord\n - a dorsal hollow nerve cord\n - pharyngeal gill slits\n - post-anal tail\n\nTo be a vertebrate it must have:\n - spinal column or backbone\n\nWhere vertebrates are a subdivision of chordates.

try searching in the net. Just type "Biometrika tables", and you can find lots of reference books for it. \n\nI hope this helps..

A symbiotic relationship in which both species benefit.

Wow, 5 people responded before me and never really answered your question.\n\nThe main question you asked was about "complex animals" compared to land plants. You were understanding this right.  Remember that those early plants were more similar to modern bryophytes (like mosses, liverworts and hornworts).  The vertebrates at that time were all sea creatures (very primitive fish-like).\n\nBy the time the land vertebrates appeared, large trees were abundant and so were insects.\n\nAlso, why do some people insist on using a book that says insects have 4 legs and calls bats birds as their science book?

Hard to say from that photo. You really need a side view or 3/4 view as well. The detail just isn't even clear enough to whether it's a beetle, a bug or a moth from that photograph.

id say the plants and animals are multi-celled and the others are single-celled. also cell specilization could be a difference.

is it........\n\n             KINGDOM\n             PHYLUM\n             CLASS\n             ORDER\n             FAMILY\n             GENUS\n             SPECIES\nis that what you are looking for.........

Duma, I see you've already asked this question twice. What you should do is contact some invertebrate researcher (in a museum or natural history institution) for help, because local keys and checklists of fauna are not easy to find unless one knows where to look for them.\n\nHere are some links to papers with reference to Asian species, that's the closest I could get.\nhttp://zoolstud.sinica.edu.tw/Journals/39.4/285-294.pdf\nhttp://zoolstud.sinica.edu.tw/Journals/40.4/276.pdf\nhttp://www.senckenberg.uni-frankfurt.de/odes/03-11.pdf\n\nHere's a link to a journal that specializes in invertebrate systematics:\nhttp://www.publish.csiro.au/nid/121/issue/529.htm\n\nAnd here's the citation of two papers about freshwater earthworms:\n \nOhtaka, A.; Usman, R. 1997. Records of tubificid oligochaetes from Padang, West Sumatra, Indonesia, with description of a new species of Aulodrilus Bretscher. Species Diversity 2: 145-154.\nOhtaka, A.; Hartoto, D.I.; Usman, R. 2000. Preliminary study on freshwater Oligochaeta in Indonesia. Rep. Suwa Hydrobiol. 12: 29-38\n\nYou coult try to contact Mr Ohtaka.\nhttp://read.jst.go.jp/ddbs/plsql/KNKY_EG_24?code=1000003153

Sounds interesting. Most cyrptids are probably legends but I think a few are real creatures. Would be very intersted in exploring which were which.

Do your own research and reading. Try sites like discoverykids.com, they have all kinds of great information on insects and animals.

could be frog, june bugs,rat,etc..

cephalopod mollusks of the genus Loligo

IFu are very much intreasted in studying that spider then take a book of PHYLUM ARTHROPODA  in invertebrate classification \nand identify the feautures like spines legs
