The green sea turtle, or green turtle, is a large sea turtle found in tropical and subtropical oceans around the world. It has a teardrop-shaped shell and paddle-like flippers. Unlike other sea turtles, green sea turtles are mostly herbivorous and inhabit shallow lagoons, feeding on seagrasses. Females nest on beaches at night, laying eggs which later hatch. Green sea turtles face threats from human activities such as hunting, pollution, and habitat loss. The hyacinth macaw is the largest parrot species, native to central and eastern South America. It is endangered due to habitat loss and trapping for the pet trade.
