Document Summary

Phylum arthropoda: spiders, scorpions, ticks, mites, crustaceans, millipedes, cenipedes, insects, open circulatory system *, coelomate protostomes w. well-developed organ system, cuicular exoskeleton. Chiin and scleroized protein prominent: have various segments fused/combined called tagmata. Head and thorax: appendages specialized for walking/swimming/lying/eaing, arthropods difer from annelids. 1: marine, freshwater, terrestrial, free-living parasiic, bilateral symmetry; segmented body, tagmata; head and trunk, triploblasic, small coelom (adult, cuicular exoskeleton, complete digesive system, complex muscular system, parthenogenesis, sexes separate, metamorphosis, open circulatory system. All arthropods that possess mandible: form clade mandibulata, includes. Arthropods that do not possess mandibles possess chelicerae. Subphylum chelicerata: horseshoe crabs, spiders, icks, mites, scorpions. Phylum onychophora: velvet worms, paired excretory organs (nephridia, combinaion of both male and female sex organs (monoecious, lack true exoskeleton, open circulatory system, walking legs with claws, paired mandibles, air tubes trachea. Phylum tardigrada: herbivores, pointed stylets piercing.
