Splitting from its ancestor, the royal scylarian has adapted to feeding on the scuttleball gillfin. Tending to live around colonialball colonies of all kinds, they wait for one of their favored prey to arrive before striking with a powerful, crippling bite. Speed has become less important for them, as their prey is forced to come to them, and there are not many predators they need to fear throughout most of their range. Their sharp, needle-like teeth prevent their prey from escaping once bitten. Young royal scylarians feed instead on hitchhiker scuttler, rooting them out of the colonialballs. They are at greater risk of being preyed upon, so they typically live along the coasts where fewer predators are to be found.
