This structure proves fish are vertebrates
What is the vertebral column (backbone)?
This fin provides propulsion.
What is the caudal (tail) fin?
Fish breathe using these organs.
What are gills?
A trait that helps an organism survive and reproduce
What is an adaptation?
Swimming in large groups to reduce predation.
What is schooling?
This sensory system detects vibrations in the water.
What is the lateral line?
These fins are used for steering and braking.
What are pectoral fins?
This process moves oxygen from water into the blood.
What is diffusion?
Physical features of the body that improve survival.
What are structural adaptations?
The process by which helpful traits are passed down over generations.
What is natural selection?
This structure protects the gills in bony fish.
What is the operculum?
This body shape reduces drag in water
What is a streamlined body
This exchange system increases oxygen absorption efficiency.
What is countercurrent exchange?
Internal processes that help survival.
What are physiological adaptations?
Deep-sea fish often use this ability to produce light.
What is bioluminescence?
These structures reduce friction and protect the fish’s body.
What are scales?
Forked tails are best suited for this type of movement.
What is speed
Without a swim bladder, sharks rely on this to stay afloat.
What is constant swimming (or oil-filled liver)?
Actions that increase survival chances.
What are behavioral adaptations?
Slower metabolism helps deep-sea fish conserve this
What is energy?
This internal organ controls buoyancy in most bony fish.
What is the swim bladder?
Rounded tails are best suited for this type of swimming.
What is maneuverability/control?
This gas-filled organ helps fish conserve energy.
What is the swim bladder?
This camouflage pattern is dark on top and light underneath.
What is countershading?
Adaptations are evidence of this scientific theory.
What is evolution?
