The term 'Pelican's Prominent Feature' can be answered with the four letter word 'BEAK'. The BEAK of a pelican is its most recognizable feature, and is used for a variety of purposes. It is used to catch and hold food, as well as to preen feathers and groom. The BEAK is also used to help the pelican dive underwater in search of food. The shape of the BEAK is adapted to the type of food the pelican eats, with some species having a longer, more pointed BEAK for catching fish, while others have a shorter, broader BEAK for scooping up crustaceans.
