Like their land dwelling cousins, the aquatic unicorns communicate by forcing air through the hollow chambers of their horns, creating a whistling or moaning sound. They also have manes like their cousins, though the hippocampus's are much shorter, and extend farther along the back. The hippocampus has the largest horn of the unicorn species, which can be twice the length of the hippocampus's head. While the other unicorn species usually only have one foal at a time, twins are common among hippocampus. More fun with postwork. Same stuff as before, Daz Cyclorama, Heart of the Ocean, and hippocampus; RDNA lights, caustics, rocks and plants; Bloodsong's hair and fur brushes.
