Monarch butterfly group 3D animation model
Monarch butterfly is a large butterfly, belonging to the family Papilionidae. The wings are orange with blackish veins and margins, and a row of small white spots along the edges. This unique color combination makes it very eye-catching when flying. The life cycle includes four stages: egg, larva, pupa and adult. The larvae feed on milkweed, a plant that contains toxins that gives monarch butterflies a certain defense against natural enemies after they become adults. The adults mainly feed on nectar, have strong flight ability and long migration distance. The most famous feature is its large-scale migratory behavior. This migratory behavior is one of the most spectacular phenomena in the insect world.

Southern giant terror bird skeleton
The southern giant terror bird (Dinornis robustus) is a species of terror bird, also known as the South Island giant terror bird. Like other terror birds, they cannot fly. The origin of these birds may be due to the early ancestors of terror birds being able to fly and reach the South Island of New Zealand. The southern giant terror bird is the largest among terror birds. Adult female birds can reach a shoulder height of up to 2 meters and a total height of 3.6 meters, making them the tallest known bird species. It lives in the lowlands of the South Island of New Zealand. It may have become extinct as early as the 13th century.
14 million year old scorpionfish fossils
Scorpion fish is one of the most venomous and inconspicuous fish species in the ocean. These ambushing predators are experts in integrating into the environment, sitting patiently at the top of coral reefs waiting for unsuspecting prey to swim over.

Due to multiple reasons such as ruthless hunting by humans and the deterioration of the ecological environment in their habitats, Przewalski's horses became extinct in the wild in the mid-20th century.
Titan python fossil
The Titan Python belongs to the Python family. Titan pythons lack external and middle ears, resulting in delayed hearing; The olfactory organ grows on the tongue; Without eyelids, one cannot close their eyes; There are lungs. The fossils of the Titan Python can be traced back to the Guajira Peninsula in northeastern Colombia, South America, approximately 60 to 58 million years ago. The Titan Python dominated the Earth for at least 10 million years. Titan pythons are cold-blooded animals with a habit of sunbathing and hunting after their bodies become warm. According to researchers' analysis, the food of the Titan Python includes blunt nosed crocodiles weighing half a ton, lungfish up to three meters long, and some large turtles.
Javanese Rhinoceros Specimen
The Javan rhinoceros is a mammal of the Rhinoceros genus in the Rhinoceros family, also known as the small unicorn rhinoceros. Strong and robust physique. The skin is mostly brown black, gray black, and has wart like protrusions. Except for obvious hair on the tips and tails of the ears, the rest of the body is almost hairless.
