Aplysia Sea Slug in Gulf of Mexico (Second Sighting)

Spotted this in a Gulf of Mexico bay off the coast of Florida. I had no clue what it was. This was is my second time spotting one.

I believe this is a Aplysia sea slug A.K.A the Sooty Sea Hare, but I am not from Florida. Now that I have moved here I am trying to learn the native species. So please let me know if this is not the Aplysia sea slug.
