Lots of Sea Monsters Were Probably Whale Dongs
A lot of sea monster legends can be explained by exaggerated sightings of perfectly ordinary ocean dwellers -- the kraken was probably an already unacceptably large giant squid, mermaids were probably manatees viewed through the lens of half-starved and full-horny sailors, etc. But there aren't a lot of known creatures that can account for descriptions of sea serpents. An eel-like body with enough power to thrust itself high above the water? That's no whale
ecologist Charles Paxton had ever heard of. But there
was something that, he realized, matched those descriptions: a whale's hoodilly.
"Many of the large baleen whales have long, snake-like penises," he wrote in a 2005 paper. "If the animal did indeed fall on its back, then its ventral surface would have been uppermost and, if the whale was aroused, the usually retracted penis would have been visible." It turns out, if you're pretty far away and getting most of your hydration via rum, that looks an awful lot like a serpent's head or tail.
In fact, if one frisky cetacean was prowling for some fin in one area and another was doing the same some distance away, their respective wang-doodles could be mistaken for the head and tail of one creature, giving the impression of a truly imposing dong-beast. This likely accounts for sightings of monsters "longer than our whole ship" or, tellingly, in the middle of a pod of whales "frantic with excitement." The next time you hear something go bump in the night or just get a strange feeling you're not alone, take heart: It could just be someone's dick.

Scroll down to the part about whale 'dongs' but actually is all a good read.
I am pretty sure he used the exact same ones in the link you posted. It is probably quite a niche market in photography to be fair..
