What is the beak of a seagull? Seagull's mouth is orange, and there are two small black spots at the end of its mouth. Seagulls catch fish with their mouths. Seagulls have webbed claws, which are not as sharp as those of sea eagles, and it is more laborious to catch things. I usually catch fish with my mouth. They can see the small fish underwater in the sky of 10 meter or 20 meters or even higher, and then rush down one by one. When seagulls fly, they can put a small fish in their mouths and swallow it in the air. From seeing the target to catching fish and eating fish, the whole action is completed in one go in flight, without any delay, very quickly.
