Sea cucumber is a highly nutritious ingredient, along with ginseng, bird's nest, shark fin, is one of the culinary treasures. According to the data, there are about 1100 kinds of sea cucumbers in the world, but most of them are inedible. We often see that sea cucumbers are dark and black. But sea cucumbers have more than one color.
1. Yellow sea cucumber, also known as yellow wart sea cucumber, yellow thorn ginseng, mainly distributed in the Indian Ocean waters. It is bright yellow all over and is an omnivorous sea cucumber. Yellow sea cucumbers have a mild personality, and some people will raise yellow sea cucumbers as ornamental sea cucumbers.
Coincidentally, the Chinese "Jiaolong" manned submersible photographed yellow long-tailed butterfly ginseng in the submerged survey area.
2. Purple Sea Cucumber: A purple long-tailed butterfly ginseng sea cucumber over 30 cm long photographed by the Jiaolong manned submersible at 4743 meters in the Mariana Trench. It is reported that the maximum length of purple long-tailed butterfly ginseng can reach one meter, which is amazing.
In 2008, China's scientific and technological personnel found extremely rare pure purple ginseng in the natural seas, and then carried out screening and seed selection technology research, and began the process of artificial industrialization.
3. Transparent sea cucumber: The "Jiaolong" manned submersible found a transparent sea - Mariana sea cucumber - 7,000 meters underwater in the Mariana Trench.
Transparent sea cucumbers have also been found at depths of 2,750 meters on the seabed in the northern Gulf of Mexico.
4. White sea cucumber: The "Jiaolong" manned submersible found white sea cucumber - dark ginseng in the polymetallic nodule area of 5000 meters underwater in China.
In fact, there is also a white sashimi called "white jade ginseng" in sea cucumbers. It is a genetic variant and is very rare. In 2009 and 2010, artificial breeding has been carried out using white ginseng, providing the possibility of large-scale cultivation of white ginseng.
