It kind of does, how could I have gotten it. I didn’t see it yesterday

Did you get any live rock, or coral recently?

That is called a black elephant slug! It is actually a snail, and a very good CUC member! I have several in my tank. It's a keeper

Agreed with this - it seems to be a Scutus sp. snail; also known as an Elephant Slug. Most species in the genus are good to have.
