Well, I'd say that it's a creature specific power.

Persuasion was called that because of Rumple's words. I would advocate a name change, but there's not much concern to me. Ursula has powers that are often confused between sirens and mermaids and sometimes they were the same thing. Anyhow, it did sort of hypnotize them by putting them at a sense of ease and comfort eve when danger is ahead. So, it's technically not hypnosis, but Mermaid magic, as they also can travel between worlds.
