100

This structure proves fish are vertebrates

What is the vertebral column (backbone)?

100

This fin provides propulsion.

What is the caudal (tail) fin?

100

Fish breathe using these organs.

What are gills?

100

A trait that helps an organism survive and reproduce

What is an adaptation?

100

Swimming in large groups to reduce predation.

 What is schooling?

200

This sensory system detects vibrations in the water.

What is the lateral line?

200

These fins are used for steering and braking.

What are pectoral fins?

200

This process moves oxygen from water into the blood.

What is diffusion?

200

Physical features of the body that improve survival.

What are structural adaptations?

200

The process by which helpful traits are passed down over generations.

What is natural selection?

300

This structure protects the gills in bony fish.

What is the operculum?

300

This body shape reduces drag in water

What is a streamlined body

300

This exchange system increases oxygen absorption efficiency.

What is countercurrent exchange?

300

Internal processes that help survival.

What are physiological adaptations?

300

Deep-sea fish often use this ability to produce light.

What is bioluminescence?

400

These structures reduce friction and protect the fish’s body.

What are scales?

400

Forked tails are best suited for this type of movement.

What is speed

400

 Without a swim bladder, sharks rely on this to stay afloat. 

What is constant swimming (or oil-filled liver)?

400

Actions that increase survival chances.

What are behavioral adaptations?

400

Slower metabolism helps deep-sea fish conserve this

What is energy?

500

This internal organ controls buoyancy in most bony fish.

What is the swim bladder?

500

Rounded tails are best suited for this type of swimming.

What is maneuverability/control?

500

This gas-filled organ helps fish conserve energy.

What is the swim bladder?

500

This camouflage pattern is dark on top and light underneath.

What is countershading?

500

Adaptations are evidence of this scientific theory.

What is evolution?
