The huge mouth and throat sac make the pelican appear top heavy and light. When pelicans walk on the ground, they always stagger. This is because the pelican's big mouth is very troublesome. Especially when it catches its prey, its big mouth and throat bag are full of sea water, which makes it difficult to surface. The pelican's "big mouth" characteristic describes that person who can't keep secret and always slips his tongue.

Pelican is a general term of 8 species of waterfowl. It is about 150cm long and has dense and short feathers. The feathers are white, peach red or light grayish brown. Some species of pelicans are larger, with wings 3 meters wide and can fly long distances at speeds of more than 40 kilometers per hour. The mouth is more than 30 cm long and has a large skin bag formed by connecting the lower mouth shell with the skin; The skin bag can stretch freely. There is a yellow oil gland at the root of the tail feather, which can secrete a large amount of oil. The oil is used to coat the feather to keep the feather smooth and soft and easy to avoid water.
