Not very clear what it is. Having lived in Florida for most of my adolescent life, though, it reminds me a LOT of old cypress stumps or burnt mangrove trunks, though not usually quite that tall. My off-the-cuff guess is it's either rocks or old tree trunks, carefully altered pixel-by-pixel via paint or photoshop or PSpro or another app.
A few things that stand out to my (untrained) eye - three lumps suggesting heads, one with dots suggesting a reflection on eyes - but a strong light artifact on the primarily visible creature's left shoulder suggests strong sunlight to his/her left, which wouldn't cause the eyes to reflect as they seem to. My guess - film artifact or manipulation. Second - the black of the three lumps seems unnaturally dark compared to the rest of the scene (though the left lump, not so much so). Third - the rightmost lump, upon close examination, has an almost gorilla-like face - except that it appears to be missing the top of its head entirely. Unless lump 3 is supposed to be a ridgeline on lump 2's head, perhaps...
The perspective also looks a bit misleading - the helicopter on the left could quite possibly be further away than the lumps on the right, meaning those lumps could be smaller and more likely rocks or old stumps. The foreground obscures the base of the brushline so badly, it's hard to say where the brush actually is for either side of the picture.
As photos go, I'd say it's probably worth, oh, the price of a post card.
