What did Scylla look like? Homer gives her six heads armed with triple rows of teeth on her shoulders. Ovid gives her six dog’s heads at her waist and twelve dog’s legs. Neither of them mention the long mermaidy fish-tail that she’s usually depicted with in art (where she’s a sort of mermaid with a dog or two grafted to her waist).
So which is right? One or all of them? Rodney Matthews’ excellent illustration from The Usborne Book of Greek and Norse Legends (1987) bravely tries to include as much as possible.
All in a very alien sort of look. No twelve legs though.

Considering the nature of the religion Scylla operates in (Hellenic Polytheism), I’d say all of them are correct. Plus, Scylla is a water spirit. Water is fluid so I imagine that Scylla can be fluid too (as in, Scylla can have many variants in form). Other marine divinities like Proteus seem to have this quality too

What i hate is that anime and stuff portrays them as sexy octopus girls. Which i don’t know where that perception comes from.

Well, a long time Ago I was picked to be Scylla in a School Play. Funny thing, I’m Male. When we Created the Costume, we Portrayed it as a Hydra-Like Creature. It had Semi-Human Heads, and rows of Teeth.

See now that is okay, at least it’s trying to be like a “real” Scylla.
