What is a fluked tail?
Flukes are the two lobes of the whale tail. While each whale has flukes, flukes themselves differ from species to species. In some whale species, flukes are so distinctive that researchers use them like fingerprints to identify individuals.
What’s the difference between a flipper and a fin?
Fins have no true bones or skeletal structure within and are composed primarily of cartilage. A flipper has a bone structure as well as cartilage, joints, and tendons.
