See the critters on the left? (Click to enlarge photo. IMAGE SOURCE.)
They’re called "sea angels" (obviously for good reason).
They’re also known as Clionidae (a.k.a. Clione).
A related species is called the "Naked Sea Butterfly."
Grow to be about 2 inches long.
Wings flap with an undulating motion.
Related to sponges.
Have shells when they are tiny embryos, then fly free after being born.
Are hemaphrodites and mutually fertilize each other in mating.
Live in the Okhotsk between Japan and Russia.
They and their relatives are an important part of both the artic and antartic ecosystems.
One kind makes a natural fish-repellant (a previously unknown molecule) to keep from getting eaten.
Cool, huh?
How many are your works, O LORD !
In wisdom you made them all;
the earth is full of your creatures.There is the sea, vast and spacious,
teeming with creatures beyond number–
living things both large and small [Ps. 104:24-25].
I remember seeing the sea angels as a kid along the waters at Herschel Island, Yukon one fall…there was alot of jellyfish that yr, very sparkly when the water was moved…& the angels happen to be one of them.
Wonderful pictyure
