Flatworm?

I caught this crawling on my glass today. Doesn’t appear to look like a planaria from my google search. Does anyone know what it is?

It looks to have a sort of a "hammerhead". That is a common trait with planaria. Can you see two eyespots?

It appeared to have passed in the container I moved it to.

If its yellow, it may be a like a Sacoglossan sea slug which feeds on coral and one you dont want

the 100% id on OP’s slug is elysia obtusa.

you can see the pigments of chlorophyll from its most recent meal and the white fringes…
which are a dead giveaway…
