Pick a difficulty and question count to begin.
Fins, teeth, and skin are more than labels—they’re tools sharks use to swim efficiently, hunt, and stay protected. This quiz helps you connect each feature to its function, so anatomy facts actually stick.
Every question uses 4 options and there’s no timer, so you can think through details like fin roles, tooth types, and how dermal denticles affect movement.
Many players confuse fin function (stability vs propulsion) or assume all sharks have the same tooth design. Watch for wording that hints at function (turning, lift, braking) and remember tooth shape often reflects prey type.
Difficulty is mixed on purpose: you’ll see easier identification items alongside more applied questions to keep practice balanced. Before you start, choose your preferred question count and select an easier or harder difficulty setting to match your comfort level and time available.
