Editing Ianthina (section)

== Tails ==
Everything mentioned about fins also applies to ianthina tails. Their tails are flattened, like rudders, and very powerful and muscular: the tails provide most of their forward motion when moving in the water. The fins on their tails catch water, pushing it aside in a side-to-side motion. The rarer the tail, the less effective this process is. Bifucated, short, and long tails are notably impaired in swim speed. Long-finned ianthinas in particular tend to have trouble. Their fins are easily targeted by wandering predators, and it's extremely common for their fins to become tattered or acquire holes as they age. Because of this, in [[Olitskur]], long-finned ianthina are typically viewed as beautiful, fragile, and delicate, regardless of their actual personality.
