The dorsal armor is dark brown or dark green, with yellow spots on it, and the scutellum is arranged in mosaic, with beautiful color. The limbs are specialized into fins, the forelimbs are longer than the hindlimbs, and the medial side has 1 claw each. The claws of the male forelimbs are strong and curved into a hook shape. Widely distributed in tropical and subtropical marine and coastal waters. In China, green sea turtles are distributed from the coast of Shandong in the north to the Beibu Gulf in the south. It mainly inhabits coral reefs, salt marshes and seagrass beds, and spends most of its time in shallow coastal waters with lush seagrass beds. Seaweed as a staple food, occasionally also eat mollusks, arthropods or fish.

The snail is a terrestrial taxon of the mollusk phylum gastropod, which belongs to the group of invertebrates. The body is soft and usually protected by a spiral hard shell. The head has two pairs of antennae, the longer one for sensing the environment and the shorter one associated with smell and taste. The foot is muscular and moves slowly on various surfaces by secreting mucus. The shell is one of its distinctive features. The shape and color of the shell vary from type to type. It is not only a protective device for snails, but also helps them retain moisture and adapt to a dry environment. It is an omnivorous animal that feeds on the leaves, stems and fruits of plants, and some species also eat humus or small insects.

It is a type of reptile that lives in the ocean, belonging to the order Turtles and family Turtles. Distributed in tropical and subtropical waters around the world, it feeds on seagrass, jellyfish, mollusks, and crustaceans. Long lifespan, some individuals can live to over 100 years old. The body is streamlined and the limbs have evolved into paddle shaped fins, making it very suitable for swimming in water. The shell is divided into the carapace and the plastron, with the carapace being their main protective structure and the plastron providing stability during swimming. The breeding method is special. Females will build nests and lay eggs on the beach, then bury the eggs in the sand and rely on the heat of the sun to naturally hatch. Many species are listed as endangered.

It is a unique marine organism belonging to fish, but its morphology and living habits differ greatly from common fish. They have a horse like head, a curved neck, and a long tail, and the most prominent feature is that their males have a brood sac where they can hatch eggs. The fins are very unique, including a dorsal fin, a pectoral fin, and a small pelvic fin, which enable them to stand upright and move slowly in water. The skin is covered with bony rings, which are composed of hard bone plates and provide protection. Mainly distributed in tropical and subtropical waters around the world, it usually inhabits seaweed beds, mangroves, and coral reefs.

It is a creature that lives in the ocean and is known for its unique appearance and behavior. They usually have transparent or semi transparent bodies, making them almost imperceptible in water. The body structure includes an umbrella shaped top and many slender tentacles, which are not only used to capture food but also as tools for defending against predators. Swimming by contracting and expanding its umbrella structure, the movement is elegant and slow, giving a dreamy feeling. It is a food source for many marine organisms and also a part of the marine food chain. Although their appearance may be fascinating, some species of jellyfish are toxic.

It is a large land turtle living on the Galapagos Islands in Ecuador, belonging to the family Turtles. It is one of the largest surviving turtles in the world, with an adult body weight of up to 300 kilograms and a lifespan of over 150 years. Known for its massive size and slow movement speed, its carapace is dome shaped or saddle shaped, adapting to different ecological environments on the island. The significant differences in body shape and living habits among different islands in the archipelago are important evidence for Darwin's theory of evolution. Mainly feeds on plants, including herbaceous plants, leaves, and cacti. Currently listed as an endangered species and protected by international conservation organizations.

It is an endemic species only found on the island of Madagascar. The body is large, with an adult's shell length of up to 90 centimeters and a weight of up to 130 kilograms. The shell is dark brown or black with yellow or orange markings on it. The head and limbs are usually gray or yellow. It is a herbivorous animal that mainly feeds on leaves, herbaceous plants, and fruits. Living in the tropical rainforests and swamps of Madagascar, these areas provide abundant food sources and suitable habitats. The slow reproduction rate and relatively low survival rate of young turtles make population recovery more difficult. Currently listed as critically endangered species.

Chameleon is a general term for reptiles in the order Lizards, family Auchenipteridae, with the scientific name Auchenipteridae. The skin is covered with granular scales, and there are various pigment cells in the dermis that can stretch and change body color at any time; There are blunt triangular protrusions on the head; Both eyes are independent and can freely turn to different perspectives; There are ridges on the back; The limbs are relatively long, with 5 fingers and toes on both the front and back limbs, divided into 2 groups. The inner 3 fingers of the front limb are healed, and the outer 2 fingers are healed together and can be held together; The hind limbs are opposite, with the inner 2 toes and outer 3 toes healed and held relative to each other. Mainly distributed on the African continent and Madagascar Island, inhabiting trees, with a few species inhabiting the ground. Mainly feeding on insects.
