Hanyurii adrift in space
Hanyurii were a spaceborne species. They often tended to lurk near asteroid belts. As babies, they were traditionally left to fend for themselves. The Hydrans revered these creatures as gods. (TOS video game: Starfleet Command (game))
A sensor disturbance led the RIS Bouteina to tow all the babies of a hanyurii hive back to an asteroid belt. (RIS Bouteina: "Humans, Romulans and Space-Beasts")
Hanyurii mated through a ritual in which they danced around a star, released their "pollen" (really sperm) so that it could enter their pistils. (RIS Bouteina: "Midwife")
