In the vast marine world, a wide variety of creatures live, some of which are of interest due to their unique appearance and habits. Today, we are going to introduce you to a special sea urchin, which has a unique name - "sea money", that is, biscuit sea urchin.
We know that sea urchins are a common marine creature that often has a spherical or hemispherical body, as well as long spines, features that make them stand out among marine life. However, the biscuit sea urchin is different because its bones are flattened and disc-shaped, and the spines are tiny fluffy, and from a distance, it resembles a coin, hence the name "sea money".
The living habits of biscuit sea urchins are also quite distinctive. They usually live in rocky crevices or sandy seafloors in shallow areas and feed on algae and small invertebrates. Unlike other sea urchins, biscuit sea urchins release special chemicals during the breeding season that attract the opposite sex to mate. The smell of this chemical in seawater is figuratively likened to the "seafood flavor", which is one of the reasons why people often refer to them as "sea money".
The breeding process of the cookie sea urchin is just as interesting. When they find a suitable partner, in vitro fertilization is performed. After fertilization, the eggs develop into larvae, which drift around with the currents, and after a period of growth and mutation, eventually develop into mature sea urchins.
Although cookie sea urchins differ in appearance from regular sea urchins, they also possess a strong regenerative ability. If the body of a cookie sea urchin is cut off, it can grow back by regeneration. This amazing self-healing ability allows the cookie sea urchin to play an important role in the marine ecosystem.
In general, the biscuit sea urchin, a sea creature known as "sea money", has attracted attention with its unique appearance and habits. They are an important part of the marine ecosystem, and we should work to protect them and the environment in which they live. Let's look forward to the days to come, Biscuit sea urchins can live freely in the clear waters, and continue to interpret their mysterious and interesting life stories.
