Sea lion (Sea Lion) is a semi-aquatic mammal in the family Sea Lionidae, which has become a landmark species in marine ecosystems due to its foldable flippers, outer ear structure and social habits. There are 7 genera and 15 species in the world, which are widely distributed in temperate to tropical waters, and are the key link between marine and terrestrial ecology. It is mainly distributed in the North Pacific Ocean, temperate waters of the southern hemisphere and some tropical waters; it inhabits coastal rocky areas, sandy beaches, rocks or floating ice edges, and prefers shallow seas with water depth <100 meters. Mainly to fish, cephalopods and crustaceans for food.

The rhinoceros (Rhinoceros) is a large herbivorous animal in the family Mammalia (Mammalia), hoyhooe (Perissodactyla), rhinoceridae (Rhinocerotidae), known for its iconic horns and heavy skin.

Mainly distributed in tropical and subtropical regions of Asia and Africa, there are currently 4 genera and 5 species of rhinoceros family. It is a herbivorous animal that feeds on small shrubs and herbaceous plants, and inhabits open grasslands, savannas, shrublands, or swamps. Rhinos face serious survival threats, mainly due to habitat loss and illegal poaching caused by human activities. All species of rhinoceros have been listed on the IUCN Red List of Threatened Species, and the work of protecting rhinoceros is urgent.

It is a large and powerful mammal belonging to the family Rhinoceros in the order Rhinoceros. Known for its short and robust limbs, thick skin, and unique horns. Mainly distributed in tropical regions of Africa and Asia, it is one of the largest surviving land mammals. Rhinoceros horns are composed of keratin and have high medicinal value, but this also makes them a major target for illegal hunting. Poor eyesight, but very keen sense of smell and hearing. Usually mainly herbivorous, occasionally also eating some fruits and leaves. Due to habitat loss and poaching, the number of rhinoceroses is decreasing, and many species have been listed as endangered.
