E. saurus, commonly known as the eastern glass lizard, is a legless lizard found in the southeastern United States. It inhabits grassy areas, pine flatwoods, and sandy habitats. Unlike snakes, it has movable eyelids and external ear openings. Known for its ability to detach its tail to escape predators, it plays a role in controlling insect and small rodent populations.

E. saurus, commonly known as the Brown Pelican, is native to the coastal regions of the Americas. Its geographical distribution primarily includes the Atlantic and Pacific coasts of North and South America. This species is found from the southern United States through Central America and the Caribbean, extending down to northern Peru and southern Brazil.

The Brown Pelican inhabits warm coastal marine and estuarine environments. It is typically found in shallow waters near the coast, including bays, lagoons, and estuaries. These areas provide the necessary conditions for feeding, nesting, and roosting.

E. saurus plays a crucial role as a top predator in its coastal habitat. It primarily feeds on fish, which it catches by diving from the air into the water. The species is well-adapted to its environment with its keen eyesight and specialized bill to scoop up prey. Brown Pelicans often nest in colonies on isolated islands where they are safe from terrestrial predators.
