Snail
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.

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.

Gabon red soil samples
Gabonese laterite is an important mineral resource, mainly distributed in the Gabonese region of Africa. Llaterite is a type of soil rich in iron and aluminum that is commonly formed in tropical and subtropical regions. Gabonese laterite is mainly composed of iron oxides and aluminum oxides and is rich in minerals such as hematite and bauxite. Due to the large amount of iron oxides, Gabonese laterites are usually red or brownish red. The laterite is formed by long-term weathering and leaching under tropical climatic conditions. The parent rock on the surface gradually decomposes in an alternating wet and dry environment, forming a soil layer rich in iron and aluminum.

Ruby is a very hard and durable gemstone, with a hardness of on the Mohs scale, second only to diamonds. The color of ruby ranges from pink to deep red, and the intensity of the color depends on the amount of chromium in the crystal structure. Ruby usually exhibits a hexagonal crystal structure, and the crystal is usually prismatic with a flat base end face. Due to its beautiful color and high hardness, rubies are widely used in jewelry, such as rings, necklaces and bracelets.
Quartz crystals of hydrothermal deposits
Quartz crystals from hydrothermal deposits are very important mineral specimens in geology. Quartz is a common mineral with the chemical composition of silicon dioxide (SiO₂), which is widely found in the earth's crust. In hydrothermal deposits, quartz crystals are usually precipitated from silicon-rich hydrothermal solutions under high temperature and high pressure conditions. These crystals can exhibit complex growth textures, such as oscillatory banded textures, mosaic textures, and concentric ring-banded textures. Quartz crystals often contain fluid inclusions, which can provide important information about the formation conditions of the deposit, such as temperature, pressure and fluid composition.
Polished Amethyst
Polished amethyst is a popular gemstone specimen. Amethyst is a purple variety of quartz that ranges in color from light purple to dark purple and is determined primarily by the presence of iron and other trace elements. Quartz is a common mineral with the chemical composition of silicon dioxide (SiO₂), which is widely found in the earth's crust. Polished amethyst and quartz are often used in jewelry and ornaments because their luster and beautiful color make them very attractive.
