Supine shark?

http://www.cnn.com/2013/08/07/us/new-york-subway-shark/index.html?hpt=hp_t2"The shark quickly drew a crowd, as entering subway riders began to photograph and pose with the shark, even adding a subway fare card, soft drink can and a cigarette to the supine shark as props." SUPINE??? The picture shown of the shark in the link above shows him prone....or am I crazy? I always remember supination as holding a bowl of soup and I even googled it to see if I was missing a definition. What do y'all think? It cracked me up either way. How often do you see the phrase "supine shark" or hear about sharks in subways?
