- appendages that function in gas exchange and locomotion
- substance that leeches (class hirudinea) release; is an anesthetic and prevents coagulation of blood
- infolding of phylum annelida intestine
- (phylum annelida) consists of a bladder and coiled glandular loops
- these cells make up the outerost layer of the intestinal epithelium (annelida)
- functions in temporary food storage in annelids
- what are the four living groups of arthropods?
- what is the extinct group of arthropods?
- functions of arthropod cuticle:
- covering the body wall
inward folds form supporting braces (anchor internal structures and provide attachment sites)
- (arthropod) specialized sensory organs that appear on the body surface. Microscopic hair like structures
- filter the hemolymph in arthropods from the body cavity and pass it into the midgut to mix with fecal wastes
- malpighian tubules
- (arthropoda) function as a gas exchange surface
egg hatches in a nymph
- incomplete or simple metamorphosis
- a smaller version of an adult bug
- nymph and adult insects are wingless; major difference between two is size
- insects where the nymphs are aquatic and gill breathing. Majorly different from adults
- hemimetablous insects
- examples of hemimetabolous insects
- Insects that are winged as adults
nymphs and adults feed on similar vegetation
- paurometabolous insects
molts molts molts
what kind of metamorphosis is this?
- holometabolous (complete)
- examples of holometabolous metamorphosis
- what kind of symmetry distinguishes phylum echinodermata?
- what are the five classes of echinoderms that we studied?
- What class do brittle stars belong to?
- class ophiuroidea
- what are the distinguishable characteristics of class ophiuroidea?
- five slender jointed arms attached to a small central disk
- what class do sea cucumbers belong to?
- Class Holothuroidea
- What are the distinguishable characteristics of class holothuroidea?
- leathery, cylindrical body with no arms or spines
- What class do sea urchins and sand dollars belong to?
- Class Echinoidea
- What are the distinguishable characteristics of class echinoidea?
- Dermal plates fused to form a shell; moveable spines
- What class do sea lilies belong to?
- Class Crinoidea
- What are the characteristics of class crinoidea?
- Flower like body with numerous branching arms
- What class do sea stars and starfish belong to?
- Class Asteroidea
- What are the distinguishable characteristics of class asteroidea?
- five to twenty-five arms attached to a central disk with flexible spiny skin
- class marine annelids with many setae
- class of leeches
- class of earthworms and freshwater worms
- where is the intestinal epithelium in annelids derived from
- the endoderm
- excretory organs that collect fluid and processes waste
- which are larger and wrap around the esophagus: the seminal vesicles or the seminal receptacles?
- seminal vesicles
- contain the testes (annelids)
- seminal vesicles
- receive sperm released by mate (annelids)
- seminal receptacles
- sensory device located above the mouth (earthworm)
- what are the three layers of the arthropod cuticle?
- horshoe crabs, spiders, scorpions, daddy long legs, ticks, and mites belong to this class
- covers the cephalothorax of crustaceans
- crayfish claw
- opening on the base of 3rd walking legs (female crayfish)
- oviduct openings
- (female crayfish) opening between 5th pair of walking legs
- seminal receptacle opening
- (male crayfish)opening on 5th walking legs
- vas deferens opening
- order flies belong to
- order butterflies and moths belong to
- order beetles belong to
- order bees, wasps, and ants belong to
