Seagulls are very common birds that live near the sea. They have webbed feet so they can paddle in water. Gulls catch and eat fish and will also scavenge for dead fish and trash people have thrown away.
Seagulls are very common on rubbish dumps and garbage tips.
Skulls are a bony structure that is found inside your head, and in the head of almost all animals. The top part of the skull is called the cranium and the bottom part is called the mandible. Your mandible is more commonly called your jaw, and is the part that moves up and down as you chew or open and close your mouth.
