It is a dolphin species widely distributed in warm waters around the world. Named after its distinctive feature - a short and thick snout (commonly known as a "bottle nose"). Large in size, adult individuals can reach a length of 2.5 to 4 meters and a weight of 350 to 635 kilograms. The body is streamlined, the skin is smooth, and the color is usually dark gray or blue gray, with a lighter abdomen. It is a highly socialized animal that usually moves in groups, with group sizes ranging from a few to several hundred. They feed on fish, squid, and other marine organisms, and use sonar to locate their prey during hunting. Very intelligent, with high learning and problem-solving abilities.

It is a larger species in the family Turtles. Widely distributed in warm waters around the world, it mainly feeds on seagrass and seaweed, and occasionally consumes jellyfish and mollusks. The shell is elliptical in shape, with colors ranging from olive green to dark brown. The scales on the shell are arranged neatly, providing excellent protection. The lifespan is relatively long, generally reaching around 80 years old. The breeding season usually occurs in summer, and females return to their place of birth to lay eggs, with each egg laying up to a hundred or more. Due to overfishing and habitat destruction, green sea turtles are currently listed as endangered species and require more protection measures.
