parapodia
appendages that function in gas exchange and locomotion
substance that leeches (class hirudinea) release; is an anesthetic and prevents coagulation of blood
hirudin
infolding of phylum annelida intestine
typhosole
(phylum annelida) consists of a bladder and coiled glandular loops
nephridia
these cells make up the outerost layer of the intestinal epithelium (annelida)
chloragogen
functions in temporary food storage in annelids
crop
what are the four living groups of arthropods?
cheliceriform
myriapod
crustacean
hexapoda


what is the extinct group of arthropods?
trilobite
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
sensilia
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
tracheoles
(arthropoda)
egg hatches in a nymph
incomplete or simple metamorphosis
a smaller version of an adult bug
nymph
nymph and adult insects are wingless; major difference between two is size
ametabolous
insects where the nymphs are aquatic and gill breathing. Majorly different from adults
hemimetablous insects
examples of hemimetabolous insects
dragonflies
mayflies
stonefles

Insects that are winged as adults
nymphs and adults feed on similar vegetation
paurometabolous insects
egg
larva
molts molts molts
pupa
adults
what kind of metamorphosis is this?




holometabolous (complete)
examples of holometabolous metamorphosis
butterflies
flies

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

polychaeta
class of leeches
hirudinea
class of earthworms and freshwater worms
oligochaeta
where is the intestinal epithelium in annelids derived from
the endoderm
excretory organs that collect fluid and processes waste
nephridium
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)
prostomium
what are the three layers of the arthropod cuticle?
epicuticle
procuticle
epidermal cells

horshoe crabs, spiders, scorpions, daddy long legs, ticks, and mites belong to this class
