background image Bio 203 Exam 4 Study Guide Phylum Arthropoda:
-bilateral and triploblastic
-body segmented both internally and externally
-Tagmosis: fusion of metameric body plan (process differs in different groups)
-cuticle forms a rigid exoskeleton (composed of chitin)
-jointed appendages (name implies)
-usually a pair of compound eyes (ommatidia)
-coelomate (true body plan)
-open circulatory system called a hemocoel (“blood space”)
-gut complete, well-developed
-well developed nervous system
**functional cilia absent except in sperm in some groups (don’t know why)
-growth by molting (Ecdysis) this leaves them vulnerable for a short period of
time (soft shell crabs)
-dioecious (gonochoristic)
-Subphylum Trilobitomorpha
-the trilobites 
-extinct: vs extant:
-body made up of a distinct head (cephalon) fused to the posterior portion of 
the body (pygidium) 
-head bears antennae
-two well-developed eyes 
-four pairs of appendages
-mortality plates:
-Subphylum Uniramia
-body compose of 3 tagma (tagmata)
-all appendages are multi-articulate and uniramous (one unit)
-head with antennae and mandibles and various numbers of feeding 
appendages depending upon group
**mandibles are whole-limb jaws with a single biting surface at the tip
-gas exchange by tracheal system with spiracles (holes on the sides of 
organism that allow for respiration)
**malphighian tubules for excretion (“kidneys”) 
-compound eyes in most with ocelli
-primarily dioecious 
-Class Myriapoda
background image -the centipedes (hundred-leggers) *really fast
-predaceous: active predators
-poison “claws”
-1 leg per somite (segment)
-legs number from 15-174 pairs
-Class Myriapoda: Subclass Diplopoda
-millipedes (the thousand-leggers)
-herbivorous scavengers 
-two legs per somite/tergite (segment)
-slow moving; warning coloration common (hydrocyanic acid; volatile 
compound)
-labrum: covers mouth area
-Class Insecta: Hexapoda Insects
-head, thorax, and abdomen (tagmata)
-specialized mouth parts
-open circulatory system
-trachea: area where oxygen is being transported (spiracle is the opening)
-malphighian tubules: osmoregulation/ excretion
-dioecious
-6 legs
-metamorphosis: 
Hemimetabous: half metabolists; egg, larvae (nymphs), adult; larval stage 
looks like adults                         
Holometabolous: whole metabolists; eggs, larvae (caterpillar), pupa 
(crystalis), adult; larvae don’t look like adults
-Insect Orders:
-Lepidoptera: butterflies and moths
-Coleoptera: beetles (largest order)
-Isoptera: termites (Eusocial)
-Odonata: dragonflies
-Orthoptera: grasshoppers, crickets
-Hymnoptera: bees, wasps, ants
-Homoptera: cicadas
-Hemiptera: true bug (stink bugs)
-Diptera: flies
-Mantoda: praying mantis
-Subphylum Crustacea
-body composed of a head and thorax that are fused and termed a 
cephalothorax 
-usually a distinct abdomen is present (tagmata)
-appendages are multiarticulate and jointed as all arthropods (resilin: makes 
up the joints that gives them elasticity)
background image -mandibles or jaws are multiarticulate limbs and are considered gnathobasic
-gas exchange usually by gills (very thin cuticle)
-excretion by nephridia (green gland, crawfish)
-compound eyes in most taxa with ocelli in some or both 
-monoecious and dioecious 
antennae:
antennules:
-Subphylum Chelicerata   
-body composed of 2 tagmata called the prosoma and the opisthosoma 
(sometimes referred to as the cephalothorax and abdomen)   
-the appendages of the prosoma are the chelicerae (jaws) and the pedipalps 
(sensory and sometimes reproduction appendage) with four pairs of walking 
legs
-antennae absent
-appendages are multiarticulate
-gas exchange by book lungs or trachea
-excretion by coxal glands and or malphighian tubules     
-compound eyes, modified eyes, and ocelli (jumping spiders have retina)
-dioecious and gonochoristic
-living fossil: a creature that hasn’t changed its morphology (shape) since the
fossil record (king crabs or horseshoe crabs)
-Class Arachnida
-spiders, ticks, mites, scorpions
-prosoma (anterior tagma) with four pairs legs
-opisthosoma (posterior tagma) lacks appendages 
-no compound eyes
-terrestrial and a few freshwater species
-dioecious (gonochoristic)
-Class Merostomata: Subclass Xiphosura
-horseshoe crabs (king crabs)
-all marine
-common along most tropical to subtropical coastlines
-trilobite larvae
-living fossils
Phylum Mollusca:
-bilaterally symmetrical (larva)
-coelomate (eucoelomate)- reduced in some groups
-open circulatory system
-most groups with mantle that secrete calcareous epidermal spicules called 
shell plates (shells)
-heart very well-developed with chambers
