1. Baleen Plates: These are the unique, comb-like structures found in baleen whales' mouths. Instead of teeth, they have rows of these plates made of keratin (the same material as human hair and nails) that filter out tiny crustaceans and fish from the water.
2. Flukes: These are the large, horizontal tail fins that propel whales through the water. They are powerful and flexible, allowing for both forward movement and complex maneuvers.
3. Blowhole: This is the opening on top of a whale's head that allows it to breathe air. Whales are mammals, and they need to come to the surface to take in air through their blowhole. The shape and location of the blowhole vary depending on the species of whale.
