Acanti

Acantis are a species of sapient whale-like beings who naturally can float through space at a speed exceeding light. Many of them were enslaved by the Broods.

Today, they are not enslaved by the Broods, because t hey are extremely peaceful and gentle towards all sapient species and sapient beings (especially Broods), except  vampires  due to bloody conflicts with them, because some of them are currently enslaved by vampires (while some were enslaved by anime teenagers to do their chores). Also, they know how to live not only in space, but also in the skies of Earth and all of the United Federation of Earth's colonies. They are omnivores that feed on the same kind of food as many other sapient species and sapient beings.
