Seagulls are in the family Laridae. Within the family Laridae, there are many different species of gulls, but they share similar physical and behavioral characteristics.
Seagulls are found all across the Earth, particularly along shorelines, coastlines, bays, large lakes and densely populated urban areas. They are highly intelligent birds that exhibit intelligence while searching for food. For example, seagulls use rocks to crack open mollusk shells. In groups, seagulls come together and tap their feet to mimic raindrops to trick worms, causing them to emerge from the soil.
Seagulls are one of the few animal species that are able to drink both fresh water and salt water. These birds have evolved special glands that help eliminate salt from their bodies.
