Speaking of canines, the campers also examined the teeth of sharks, namely whale sharks, pygmy sharks, mako sharks, and cookie cutter sharks among others. It will be tough to go near the water after this lab, especially after seeing a tooth from the infamous C. megalodon, the largest shark ever to have lived and a close relative (chewing cousin?) of the living great whites. Reconstructions of the mighty megalodon's jaw indicate that this shark reached total lengths of at least 45 feet, had a mouth gape of about 61/2 feet and weighed more than 25 tons. This mammoth carnivore fed on large marine animals, other sharks, whales and thank goodness, SUVs. Talk about a hunk of burning love...
