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

The Sea Plate Car Sea Star, also known as the Sunflower Sea Star, is the largest known sea star in the world. In the Yellow Sea and Bohai Sea of our country, there is a type of starfish called the sea disk car. Its body is flat and shaped like a five pointed star, with a long wrist and suction cups on its legs. When this starfish moves, it is like a pole vaulter, first using suction cups to suck the ground, then supporting its body to flip and move forward one step, and then continuing to repeat this action, moving forward little by little. The diameter of the Sea Plate Car starfish is 80cm, making it the largest starfish in the world. It lives in the Pacific Ocean and has a huge stomach in the middle. Unlike other starfish, it has 24 antennae.

The snake tail starfish, also known as the snake hair monster starfish, striped snake tail, striped brittle snake tail, or tiger striped starfish, is a species of starfish in the true snake tail family. There are five brown antennae on the disc, with stripes ranging in color from brown to red. The stripes on the disc are changing. It is a newly discovered species by scientists, living at depths of up to 800 meters in the Atlantic Ocean. Nocturnal animals do not come out to hunt during the wild daytime.

Likes to live in groups and often inhabits the seabed with sand, rocks, or coral. In terms of medical value, the ingredients contained in starfish have good therapeutic effects on hyperlipidemia and cardiovascular and cerebrovascular diseases. Starfish can also extract gelatinous substances from their bodies to make capsules. In industry, it is commonly used to process into powdered feed.
