studying the different morphologys there were in the different crab species found in relation to the types of wave exposure. low, as in an esturary or harbour. intermediate wave exposure as on a shore where the waves are some what lessoned by stumps and rocks before the shore line. and high impact where the full force of the wave hits the shore line.  you will notice that sediment at all these sites is different adn this is reflected in the crab s morophology and species.  measure the carapace width and length, the length and width of the chela, take note of the crabs species and where it was found. all sorts of comparisons can be found. this was a very indepth study we did but it can be scaled down to suit a short time fram.  please if you are truley interested i would only be too happy to send you more information.

cyanobacteria, unchanged for 4 billion years!\n\nhorseshoe crab, the same for 500 million years!

They are both mammalians, why should there be a contrast?

We actually can not give a chart of living organisms and non living organisms but we can differentiate them by giving differences and similarities.\nLiving                       No living\nThey can reproduce while noliving can not reproduce \ncan locomote    while noliving can not locomote\ncan feed       while noliving can not feed\ncan respond (irritability) while noliving can not respond to stimuli\ncan excrete wastes while noliving can not excrete wastes\ncan respire while noliving can not respire

I like a very broad question.  Arachnids and crustaceans both shed exoskeletons as they grow.  The arachnids are generally land creatures comprising of spiders, scorpions etc.  Crustaceans comprise of crabs, shrimp, prawns, crayfish, lobster etc.  There are a number of crustaceans that live on land but require water to breed.  The land crab is an example of one.  They also need to shed exoskeletons.\nExoskeletons are what holds there bodies together as they have no internal skeletons.  So as the animal grows, the skin needs to be shed.\nThe arachnid need little water, gathering what they need from the animals that they eat.  The exoskeleton also reduces water lose for those that live in deserts.\nCrustaceans have evolved to live in both fresh and salt water, so the adaptations are to numerous to list.  I hope I have given you a few clues for further investigation.

Actually, amarsupials are mammals. They are a sub group just as is the other group that includes the platapus and echidna (can't remember the name of this group).\n\nThe difference is that the young is succled in a pouch. \n\nThey are born alive, not in egg, they are warm blooded, as all mammals do/are.

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

Archaepoteryx. \nFeathered dinosaurs. \nThe fact that mitochondrial drift in terrestrial organisms tend to vary mutationally in a way that appears to very closely mirror the fossil record.\nThe differences in the design of eyes in cephalopods and vertebrates, even though parallel evolution is given them similar levels of visual acuity.\nThe obvious relationship between dogs and wolves.\nThe more than obvious relationship, both morphologically and genetically) between humans and apes (i.e. explain why Malaysians named the Orangutan the way they did, as in 'orang' is Malay for 'man.')\nThe fact that humans have more vestigial tail than do chimps\nThe fact that whales have vestigial land-limbs.\nThe clear record showing the advances of horses since Eophippus in the Eocene.\nThe fact that there are fossils of beings who are very clearly human, and also very clearly not us (Homo Erectus, Ergaster, Habilis, Neanderthalensis, Florensis.)\n\nI could go on and on and on. But I know those unwilling to hear, won't anyway, so why waste the typing?

That sounds like the mantis shrimp.  It's not a crab, but it isn't really a shrimp either.  Shrimp and lobsters belong to the order decapoda.  Mantis shrimp belong to the order stromopoda.\n\nThey have two club-like apendages in front of their legs.  The power of the appendage can produce a blow close to the power of a .22 caliber bullet.  They use this club for self defense, fighting rival mantis shrimp and cracking open hard shells of its prey such as crabs and mollusks.

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

You have got to be kidding me. I have a favorite 'prehistoric water-dwelling animal'? I believe in a young earth anyway, so they're not prehistoric. I guess maybe Leviathan.

Yup and so are spiders scorpions and crabs, They all have the same exo-skeleton, and the same amount of legs   8    That puts lobsters, scorpions, crabs ,spiders, ticks and???No one knows for sure  all in the same family, BON APPETITE"

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
