Term Definition
osteichthyes osteo=bone, 98% bony, overlapping scales, operculum, fin rays, terminal jaw, swim bladder
operculum gill cover
fin rays thin membranes supported by bony spines
terminal mouth teeth generally fused to jawbone
swim bladder allows them to regulate their bouyance
fusiform fast/ pelagic
dorsal-ventrally flattened bottom/short bursts of speed
eel-like rocks and crevices/ slow
boxy rocks and crvices
dorsal unpaired, stability, lessen tendency to pitch
pectoral and pelvic paired stability, turn, stop, move back wards
anal unpaired, prevents rolling
caudal unpaired, thrust, speed reduce oscillation, direction
soft and round fin quick acceleration and maneuverability
fork less drag, faster swimming and less maneuverabilty
lunate sustained long distance fast swimming, poor maneuverabilty
nervous system smell: find food, avoid predators, mates/ vision-good/ hearing- internal system of fluid canals attached to the inner ear/ lateral line- sensitive to vibrations in water(kinda like touch)/ cerebrum not well developed
schooling protection, feeding, swimming efficiency
