I'd say the point at the lower left is the actual head, because of the alignment of the limbs/wings. The setup of it's digits isn't right for something reverse-joint legged though, there doesn't seem like there would be enough support. Then again, the lack of any other extremities aside from wings kind of implies that it doesn't live on land anyhow.
If that were the case, perhaps the large circular tail is a way of keeping afloat indefinately. A massive sac of lighter-than-air gas or such.
technically its all a matter of size, weight, and its distribution. for instance if the creature in the pic was say only 30lbs and had a wingspan of say 45ft, the legs would be more than strong enough to hold this thing up. But alchemist, you are correct in stating that the creature is purpetually in the air. It eats, sleeps, and mates in the air. the young of this creature could arguably be "born" ready to fly. eh just ideas... lol In anycase, glad to see this thread didn't go to waste
It's a carnivorous mollusk...(sharp teeth as opposed to blunt, grinding pearly whites)
Maybe uses it's tentacles like an octopus to catch prey. Probably hides in it's shell somewhere until something edible happens by. Doesn't seem like the fastest car in the garage, like it's smaller cousins.
Movement via mucus doesn't seem too practical, mass is too great. Plus most prey would smell it coming a mile away. Probably moves either like a snake, with hardened scales or parts underneath that push the creature along.
Internal temperature a possible weakness, would probably prefer cold climates due to body mass.
Conclusion: Bring over five pounds of salt when hunting in case of a slow moving mollusk attack.
whoa these are heavy! nice work! I remember reading the Titus Crow series of books by Brian Lumley... there was a point when the character traveled through dimensions... i wish I could recall the madness o lifeforms he was describing.... one that sticks is something about 'crimson veils or strings'... that was just the beginning, lol.
