tagmatization specialization of regions of the body for specific functions, as seen in arthropods
ecdysis what is the shedding process where the arthropod exoskeleton must be shed to allow growth?
metmorphosis having this between larval and adult stages of arthropods reduces competition for resources
biramous appendages of trilobites that were divided into two lobes
meristomata class that horseshoe crabs belong to
prosoma cephalothorax of chelicerates
digestive organs what does the chelicerate opisthosoma contain?
arachnida spiders, ticks, and scorpions belong to the arthropod class
arachnids most zoologists believe that these were the first arthropods to invade land
book lungs many arachnids utilize these for respiration, which are believed to be modifications of book gills
webs many spiders produce these that are used to trap small arthropods on which they feed
acarina the chigger or "red bug" is a member of the arachnid order
ticks carry and transmit the bacteria that causes Lyme Disease
aquatic the majority of crustaceans are this
carapace the portion of the crustacean exoskeleton that covers the cephalothorax
isopoda terrestrial crustaceans are quite rare, but terrestrial pill bugs belong to which order
sessile adult barnacles are unusual in lifestyle because they are this
decapoda crayfish, lobsters, and shrimps belong to which order
flight insect dominance in terrestrial environments is due in part to the evolution of this
diplopoda millipedes belong to which arthropod class
scavengers and detritivores millipedes may be categorized as this
myriapoda centipedes belong to which subphylum
head, thorax, and abdomen what are the three tagmata of insects
thorax the legs and wings of insects are attached to what
spiracles the external openings of the respiratory system of insects are what
uric acid the primary nitrogenous waste excreted by insects
malpighian tubules the excretory organs of insects
ametabolous insects in which the larvae appear to be exact miniatures of the adults exhibit what kind of metamorphosis
nymphs immature stages associated with hemimetabolous metamorphosis
butterflies which insect is holometabolous
larvae immature insects undergoing holometabolous metamorphosis are called this because they are bery different from the adult morphology
isoptera entirely social order of insects
caste each kind of individual in an insect colony
queens reproductive females in a social insect colony

chelicerata subphylum that is made up of meristomata, arachnida, pycnogonida
aranea spiders
acaria mites, ticks
scorpionida scorpions
pycnogonida sea spiders

maxillopoda barnacles, pill bugs
hexapoda subphylum that is made up of insecta
myriapoda subphylum that is made up of deplopoda and chelopada
exoskeleton provides support and protection, prevention of dehydration, sites for muscle attachment
chitinous exoskeleton, paired-jointed appendages, growth with ecdysis, pen circulatory system, complete digestive tract arthropod characteristics
metamorphosis reduces competition between stages for food and living space
chilopoda class that centipedes belong to
open what kind of circulatory system to insects have?
arthropods segmented, bilateral body; jointed appendages; exoskeleton; open circulatory system; ventral nerve cord; compound eyes
versatile exoskeleton; segmentation; oxygen piped directly to cells (terrestrial); highly developed sensory organs; complex behavior; metamorphosis arthropods' reasons for success
