You're not looking at some screenshots from a poor man's version of The Abyss. You're looking at photos taken by Rachel and her fiance while on vacation at Marco Island, FL.

Rachel's best guess, and mine too, is that this beast (there were two of them) is a sea hare (a type of marine slug). If this guess is right, then these creatures (or their kin) might have the potential of reaching upwards of 4.4 lbs and two and a half feet in length. That makes them arguably the world's largest slug (a title they've stolen from an uncle of mine). That's a lot o' slug.
