Sea Angels Arrive at Moscow’s Moskvarium in Rare Deep-Sea Exhibition

The Moskvarium at VDNKh has unveiled one of the ocean's rarest and most delicate inhabitants — translucent sea angels from Arctic waters that appear to "fly" underwater. Rare winged mollusks known as sea angels have arrived at the Moskvarium at VDNKh, giving visitors a rare opportunity to observe one of the ocean's most unusual inhabitants. According to the aquarium's press service, sea angels are among the most extraordinary creatures in the marine world. Encounters with them are exceptionally uncommon: they inhabit cold northern waters and usually live at considerable depths, while their short life cycle allows them to be observed for only a few months each year.
