A. Ampullae De Lorenzini
B. Lateral Line
C. Dermal Denticles
D. Nares
B: Lateral Line
Scales that cover the skin of sharks. The alignment of these scales channel the water resulting in a flow that acts to reduce friction as a shark swims through the water.
A. Dermal Denticles
B. Lateral Line
C. Ampullae De Lorenzini
D. Spiral Valve

This is a complex and extensive sensory system around the shark's head. It can detect weak electrical fields at short ranges. They are external pores that cover the surface of the shark's head and are filled with jelly.
A. lateral Line
B. Dermal Denticles
C. Spiral Valves
D. Ampullae De Lorenzini
D: Ampullae De Lorenzini
Swinging it forward and backward to advance in the water, it pushes the water around the fins creating a movement that produces elevation to aid with buoyancy.
A. Lateral Line
B. Dermal Denticles
C. Ampullae De Lorenzini
D. Heterocercal Tail
D: Heterocercal Tail
Cork-screw shaped lower portion of a sharks intestine. It is designed to increase the surface area of the intestine and thus increase nutrient absorption.

What hypothesis has been proposed to explain the megalodon's extinction?
The megalodon was confined to warmer water and could not follow the whales it preyed upon to cooler waters.

What are the three groups of fish?
1 correct = 500 points
2 correct = 1,000 points
3 correct = 1,500 points
1. Jawless fish (Lampreys)

Name one kind of shark that is on the endangered species list.
1. Great White Shark
2. Basking Shark

Why are larger sharks decreasing in number around the world?
They are being hunted by humans. People have used sharks for food, medicines, vitamins, weapons, and jewelry. Some sharks are caught for finning. The shark is caught and the fins are removed. The remainder of the shark is tossed back into the ocean.
What is the only shark that can survive in a freshwater environment?
Bull Shark
The bull shark is the only shark that can survive in a freshwater environment. Why can't other types of sharks survive in a freshwater environment?
Sharks require a large amount of salt in their body in order for their cells to function properly and thus must live in the salt water of the oceans.
