Clione
A clione is a genus of sea slug. They are also called sea butterflies and sea angels.
There are 16 species of Clione. They live in the ocean. The body is small, and the brain and heart are pink so they show through the clear body. Human beings like to put them in aquariums.
It is said that it was discovered by Captain Fipp of England in 1773 during whale watching off the coast of Greenland carrying the King of England.  The origin of the name is said to be "Clio" which means "a blessing woman", one of the nine goddesses of literary arts in Greek mythology, Muses.  The official name is Clione Limacina. It means the goddess of the sea like a slug. Clione is known as "the angel of drift ice" or "the fairy of drift ice", which is said to come with drift ice and leave with drift ice.  It is translucent, has a red head and tail, and has spread wings, making it a mascot of the Sea of ​​Okhotsk in winter.
Children of Clione eat plankton and become carnivorous when they grow up a little. The food they eat is limited, and they only eat Limakina, who is the same companion and has a shell. Six tentacles come out from the head and capture the Limacina.  And it is a method of slowly absorbing the nutrients of the Limakina and eating it. They eat like a devil regardless of appearance.
Fertilization occurs 4 hours after copulation, and the female lays jelly-like eggs into the sea. The phytoplankton is breeding season at that time therefore, Clione's spawning season is off the coast of Vancouver in spring. The Sea of ​​Okhotsk has a spawning season from late autumn to early summer.
It is reported that the number of eggs laid is approximately 150 to 200 in the small group with a body length of 1 cm and  approximately 1200 to 2800 in the large group with a body length of 4 to 8 cm.  And Clione matures in about one year and is said to have a life span of  two to three years.
