For a lovely "land sighting" of Andrias davidianus, the Chinese Giant Salamander, follow this link:
Of particular interest, observe the various contours of the caudal (tail) fin as the animal moves. At 26 seconds into the clip, with the fore and aft portions of the fin twisting in opposite directions, the silhouette of the caudal fin becomes a triangle with the apex at the middle, virtually the same as can be observed of the tail fins of the animal pair in the Hugh Gray photo. This also lends itself to an explanation of single sightings describing either a variable numbers of humps, or a change in the shape of a hump in mid-observation.
MYSTERIOUS PLANET BORROWS GRAY ANALYSES
If imitation is the sincerest form of flattery, I'll have to thank the producers of Mysterious Planet for this episode, created shortly after the first few posts of this blog were published. But while this episode may borrow heavily from this blog, actual credit for the giant salamander of Loch Ness theory properly belongs to Lieutenant Colonel W. H. Lane, who published it in 1934. And of course Prof. Roy P. Mackal proposed a giant amphibian in 1976. Alas, they don't rate even honorable mentions in any of the film credits.
Also, beginning around 2:20 into this mini-documentary, everything you'll see for awhile was lifted straight from this June 2011 article by Roland Watson. Without mentioning the author or giving a snippet of credit. Shame on them. Mr. Watson was the first to publish finding the head in the Heron-Allen version of the Gray Photo, or to publish any analysis of the Heron-Allen version I'm aware of at all. These people most likely wouldn't even be aware of the Heron-Allen lantern slide print without Mr. Watson's research. So again, shame on them. Other than that, they did an excellent little job:
