crown of thorns starfish
The crown-of-thorns starfish is a well-known top predator of coral reefs in the Asteroidea class (starfish). Its scientific name is now mostly classified as Acanthaster planci (often translated as "crown-of-thorns starfish" or "coral starfish" in Chinese). This kind of starfish is called "the nightmare of coral reefs" because its large-scale outbreak can lead to the death of large-scale bleaching coral reefs, is a key regulator of tropical coral reef ecosystems
Flat Coral
Flat coral is the "invisible cornerstone" of coral reefs-its dense skeleton, symbiotic relationship with zooxanthellae, and support for biodiversity make it a core species for maintaining reef health. In the face of climate change and man-made air disturbance, protecting this "flat engineer" is essentially injecting resilience into the entire coral reef ecosystem. Every gentle guardian of a coral reef is an investment in the future of the ocean.

Cauliflower coral specimen
This type of coral lives in tropical and subtropical regions of the Indian Ocean and Pacific Ocean. They usually form clustered groups up to 30 centimeters in height, with irregular wart like protrusions on the surface. Cauliflower coral comes in a variety of colors, including green, pink, yellow brown, or light brown. This type of coral is the main builder of reefs, growing rapidly and having strong competitiveness. Their tentacles extend at night to prey on plankton.
Panosaurus fossil
Banlong is an ancient dinosaur from the Triassic period, which lived between 222 million and 200 million years ago. It was the first giant dinosaur to appear on Earth. Before the appearance of the Banosaurus, the largest herbivore had a body size as big as a pig, while the Banosaurus was much larger, with a body the size of a bus. Banlong, meaning "flat reptile," is an ancient dinosaur that lived 210 million years ago during the Late Triassic period. It has a body length of 6-8 meters, a height of 3.6 meters, and a weight of about 5 tons. According to archaeological research, it was the first giant dinosaur that lived on Earth and ate plants.
Lianglong skeleton
Lianglong is a dinosaur belonging to the family Lianglong in the order Saurischia. The neck is long, the head is small, and the position of the nostrils is higher than the eyes; The front of the mouth has flat teeth, while the sides and back have no teeth; Strong limbs, short forelimbs, long hind limbs; The buttocks are higher than the front shoulders; Each palm has 5 fingers (toes); The tail is longer than the neck and gradually narrows towards the end, forming a whip like shape, with over 10 human bones in the middle. The name Shuanglianglong comes from two protrusions that protrude from the top of the human character bone, resembling double beams, and is commonly referred to as Lianglong.
Besikti ankylosaurus skeleton
Bissektipelta (genus name: Bissektipelta, meaning "shield armor of Bissektipelta") is a genus of armored dinosaurs in the subfamily Ankylosauridae, which lived in Asia during the Late Cretaceous period. Fossils were discovered in the Bissektipelta Formation in present-day Uzbekistan. Besiktivosaurus is a monotypic genus that only includes the type species B. archibaldi.
Curling Armadillo
Armadillo is a mammal of the family Armadillidae in the order Heterodontoides. The bone armor covers the head, body, tail, and outer legs. The bone armor in the head, front half, and back half is separated, and the bone armor in the body forms a band shape, allowing for flexible movement; Having sparse hair in areas of the body without bone armor; There are strong claws on the front foot. The armadillo is named after the nine layered ribbon on its body

Paramecium (Microscopic 3D Structure Diagram)
Paramecium is a ciliate belonging to the family Paramecidae in the order Hymenostomes. The body of paramecium is small, cylindrical, and composed of only one cell. It is a unicellular animal, hermaphrodite. The most common is Paramecium, with a body length of only 80-300 micrometers. The surface of the body is covered with a membrane, densely covered with many cilia. The paramecium is named after its body shape, which looks like an inverted sole from a flat angle.
Amoeba (microscopic 3D schematic)
Amoeba is a unicellular animal belonging to the genus Amoeba in the family Proteaceae of the order Proteobacteria. There is only a thin plasma membrane on the surface of the body, and the cytoplasm inside the membrane is relatively transparent, which can be clearly distinguished into two parts: endoplasmic and extracellular; Pseudo feet are shaped like fingers, leaves, or needles; Insects can undergo special deformation movements through pseudopodia, which change with the expansion and contraction of pseudopodia; Pseudo foot not only has the function of movement, but also has the function of feeding. After wrapping food, it undergoes intracellular digestion. Named after the constant changes in body shape caused by the movement of the parasite's cytoplasm.

Blue algae (microscopic 3D schematic diagram)
Cyanobacteria, also known as blue-green algae, are a type of large single-cell prokaryotic organism with a long evolutionary history, Gram negative staining, no flagella, containing chlorophyll-a but not chloroplasts (different from eukaryotic algae), and capable of oxygen producing photosynthesis. The difference from photosynthetic bacteria is that photosynthetic bacteria (red snails) undergo more primitive photosynthetic phosphorylation and do not release oxygen during the reaction process, making them anaerobic organisms, while cyanobacteria can carry out photosynthesis and release oxygen.

Immunoglobulin (Microscopic 3D Schematic)
Antibody (Ab), also known as immunoglobulin (Ig), is a large Y-shaped protein mainly secreted by plasma cells and used by the immune system to identify and neutralize foreign substances such as bacteria, viruses, and other pathogens. It is only found in the extracellular fluid of vertebrates, such as plasma, and on the cell membrane surface of B cells. An antibody can uniquely recognize a specific foreign target through its variable region, which is called an antigen.
Staphylococcus aureus (microscopic 3D schematic)
Staphylococcus aureus (S. aureus), also known as "Staphylococcus aureus", belongs to the genus Staphylococcus and is a representative of Gram positive bacteria. It is a common foodborne pathogenic microorganism. The most suitable growth temperature for this bacterium is 37 ℃, pH 7.4, high salt tolerance, and can grow in an environment with a salt concentration close to 10%. Staphylococcus aureus often parasitizes the skin, nasal cavity, throat, gastrointestinal tract, abscess, and purulent sores of humans and animals, and is also ubiquitous in environments such as air and sewage.
