|
Tissue supporting variously shaped jointed plates of the calcareous skeleton
|
connective tissue
|
|
|
male or female reproductive gland; produces eggs in female sea stars, sperm in male sea stars
|
gonad
|
|
|
muscles which help change the pressure in the tube feet
|
ampullae
|
|
|
Located just above the cardiac stomach--connected to pair of digestive glands in each ray
|
phyloric stomach
|
|
|
Two in every ray; connected to phyloric stomach; where absorption of nutrients take place
|
digestive glands
|
|
|
Attached to endoskeletal plates; enable sea star to move arms to move and to capture prey.
|
muscles
|
|
|
Tint pincer-like calcareous jaws on the aboral surface; keep body surface clean
|
pedicellariae
|
|
|
terminal disc of tube feet
|
suction disc
|
|
|
structures on the oral surfaces of the rays; used to capture smaller prey and for locomotion
|
tube feet
|
|
|
outer cell layer forming the skin of the sea star
|
epidermis
|
|
|
internal calcareous sea star skeleton; composed of various jointed plates
|
endoskeleton
|
|
|
deepest layer of body wall; lines the coelom; surrounds tube feet
|
parietal peritoneum
|
|
|
dorsal (top) surface of the sea star; side on which anus is located.
|
aboral
|
|
|
Can be everted about prey; releases enzymes onto prey to digest & liquefy it
|
cardiac stomach
|
|
|
layers of peritoneum supporting internal organs in the coelom
|
mesentery
|
|
|
opening on aobral surface through which solid digestive waste can be excreted.
|
anus
|
|
|
opening on aboral surface through which solid digestive waste can be excreted
|
coelom
|
|
|
body cavity; from where oxygen is distributed to all the tissues
|
visceral peritoneum
|
|
|
lines the organs (e.g. digestive glands, gonads) in the coelom
|
intestine
|
|
|
short part of digestive system, connecting phyloric stomach with anus
|
dermal gills
|
|
|
ventral (bottom) surface of the sea star; side on which mouth is located
|
oral
|
|
|
radiating arm of sea star
|
ray
|
|
|
fertilization that occurs outside the animal
|
external
|
|
|
on oral surface; opens into cardiac stomach; ingest food, might also excrete solid waste
|
mouth
|
