Was Nemo's infamous Nautilus destroyed by the Loffoden Maelstrom? We may never know the answer to that question, but there's no doubt the submarine was extensively damaged. This intriguing fragment of a stanchion was recovered by the talented Michael R. Maranda.
Update: Based on a comment below it appears the octopus finial is actually a sculpt from artist Michael Locascio. My apologies for any confusion.
