Saw one of those monster isopods on "Science of the Deep" (Science Channel) - totally grossed me out! I have a deathly fear of insects on land, and my husband always teases me about how I don't seem to be bothered by insect-like ocean critters (lobsters, shrimp, etc). To me, they're nothing like bugs.
But THAT thing... yuck. Just makes me think of a gigantic cockroach. I think I'd completely lose it if I even bumped into a smallish one underwater!
(Please tell me that giant one in the photo was also from the super-deep, ie, NON-DIVEABLE, part of the ocean!)
