Although scientists found its trail in the Arctic Ice Sea in 1774, its origin remains unclear. That's sea angels!
Interestingly, Western scientists used Cleo, the Greek goddess of history, to establish a new taxonomy of the family for Cleo as a representative species. Because of its slender body, it is named after the sea snail.

Because of its simple appearance and transparent body, the sea angel is often mistaken for a jellyfish, but it belongs to the shellfish family. This type of shellfish has two wings, so it is collectively called pterodactyls. They have spent their entire lives adrift in ocean currents.
The sea angel had just hatched from its egg and had a hard shell on its body, but after about three days, the shell was permanently discarded and turned into a shellless shellfish.
Although the sea angel is only 1-3 cm long, the largest is no more than 7 cm, but through the intermittent swing of its wings, it can move up and down in a layer of water thousands of times larger than its body.
As it rises, it always maintains an angelic graceful posture, slowly swimming from the deep sea to the ice. Even if disturbed by bumps and bumps, the balancer in its body can immediately signal to restore balance - swinging the tail end until it returns to a dignified and elegant posture. Only when it catches its prey will it fall down and swoop down to attack the target.

The sea angel's name is mainly derived from a pair of wings on either side of its body. It looks like an angel flying in the air. In addition, it has a red heart-shaped digestive organ in its body, which looks very sweet and cute, but it is actually a fierce carnivore.
During development, it prefers to prey on tiny planktonic algae, but when it grows up, it mutates into a ferocious predator, especially its cousin, a special species of crustacean pterygopods.
When the sea angel attacks, it sticks out three pairs of tentacles from its head. First, it will firmly grasp the hard shell of the prey, point the shell of the prey at itself, and then extend a thorny kiss, hook the body of the prey, swallow it into the stomach, leaving only the empty shell.

Although the sea angel is small, it is a key species in arctic and antarctic ecosystems. Every spring, when the sea warms, they can grow and multiply rapidly in a short period of time, forming an immeasurable population. In the polar food web, they provide a food source for a variety of creatures, especially baleen whales' favorite dishes. Come to think of it, to meet the needs of a whale's huge belly, the number of whales must be astronomical!

Sea angels are hermaphrodites. It has the sperm of a male animal and the egg of a female animal in its body, but it must be fertilized with another individual to complete this great inheritance event.
Scientists have found that during the food-rich warm spring season, sea angels not only consume a lot of fat, but also synthesize fat from other substances for breeding or as a food reserve to survive the winter of food shortages.
After a full meal, sea angels can be hungry for more than 200 days. More importantly, it can shrink the body, reduce the metabolic rate, and reduce the energy consumption in the body.
When ammunition and food are exhausted, sea angels can digest some tissues that have nothing to do with survival to save the last rays of light and wait for spring to arrive. This flexible survivability is the superpower of Haitian, enabling all ethnic groups to live in the waters of the North and South Poles!
