✦ The body of the gulls is mostly white with black wingtips and darker color on the head. However, some of them have bodies that are entirely gray or white. Ivory gulls are completely white.
✦ Unlike several birds, seagulls can drink salt water. This is due to the presence of a special pair of glands located just above the eyes. These glands help remove the excess salt from their body through openings in the bill.
✦ They have sharp claws that allow them to grab a prey, and webbed feet that allow them to paddle and propel themselves in water.
✦ They have water-resistant feathers and a sharp beak to tear through flesh.
