Apparently finding success with their show Dragons: A Fantasy Made Real, Animal Planet broadcast another provocative “Docu-Fiction” in May, 2012, later shown on The Discovery Channel, called Mermaids: The Body Found. Taking its cue from the fact that legends of mermaids are noted all over the planet, this ingenious show imagines how mer-people might have evolved, hypothesizing that proto-humans who turned to the sea instead of land might have adapted themselves into aquatic humanoids, living occasionally glimpsed, but essentially secretively and mysteriously. (The show’s premise is also a nod towards the “Aquatic Ape” theory, which wonders if early humans did not spend time adapting themselves to living in watery environments- explaining, for instance, why humans lost their body-hair, which would be an impediment to sleek swimming, as well as why human babies are born plump with baby-fat: insulation against watery temperatures.)
Some of the videos provided make fascinating mini-movies, showing these intrepid “mer-humans” in a struggle to survive the challenges of marine life- such as prehistoric sharks- as surely as early humans were beset by land predators. An especially inspirational one- one that strikes me as oddly “Pagan” in its sense- is the one where a brave mer-scout saves his tribal “pod” by offering himself as a sacrifice to a monster-shark, enabling his mer-people to swim away to safety, hopefully to survive another day (however day is measured when one lives in the ocean). Projecting a mythology upon these early “aquatic humans,” one imagines that such an individual would be remembered as a brave sea-warrior, and hero to his pod-tribe. It is a remarkable “alternative perspective” to human (sea-human) courage, and even early sea-human spirituality.

This all reminds me of Oberon and Morning Glory Zells’ (Church of All Worlds) quest to New Guinea to chase rumors of mermaids, back in the 1980s.
just an fyi, Mermaid swim suits were a big trend this year
