Dinner... is served

The Ogopogo slithered back to it's murky home.
A cave outside of the Okanagan Lake, with cleaner water, and enough seclusion from the human race to raise it's head above water when it felt the desire for air.  An ideal place to foster the fledgeling man shark.
The child had been in it's care for several rotations of the sun, barely eating anything, as the ancient creature was unsure of what the child's body could even process.  But after endless amounts of searching, it had found a nest of mollusks, easy for the child to swallow, and shells that the ogopogo could easily open.

But it returned to an empty nest.

The giant sea snake opened its enormous ears.  Like sails raising to catch wind, the angular webbed fins on the sides of it's reptilian skull opened into a conical shape, shifting and turning from side to side, scanning the reverberations of the water for signs of the child.

'Interesting', it mused.  Atlas was in the middle of sticking his head out of the water.
The Ogopogo slithered it's tremendous body up to just below the surface, perched itself on a submerged edge of rock, and raised it's monstrous head into the air.

Baby Atlas was struggling to crawl on to a rock, while feebly whipping his under developed tail.
"Silly thing.."  The Ogopogo thought to itself, as it stared in derision.
As he did, Atlas opened his eyes, becoming aware of its presence, stretched his frail arms, and pulled himself up, suddenly not sure how to breath, as his mind wasn't yet developed enough to automatically switch from breathing through gills to lungs.

As his head, neck, and torso emerged from the water, Atlas paused.  His eyes bugged out, unsure what to do, simply frozen between his worlds.

The Ogopogo leaned close to Atlas, opened it's nostrils, and inhaled, curious as to what exactly this unfortunate little miscreant's smell would be.
He smelled like a man.  A salty, scaly man.
The Ogopogo snorted in disgust, the power of the air escaping its nose blowing Atlas back into the water, where he breathed deep through his gills.

The Ogopogo waited above water to see what Atlas would do next, and to it's amusement, Atlas swam back to the rock, wagged his tail until his tiny arms could catch hold of the rocks face, and he began to pull himself up.

He failed.

The Ogopogo opened it's mouth and emptied out the mollusks, kept in a pouch located under its tongue, which was forked and long like a snake's.
It rolled them onto the rock, and picked one up with the two prongs on the end of its tongue, raised the shelled mollusk to it's mouth, and placed it between it's back teeth, which unlike it's pointy spiked front teeth, were wide and serrated.
It waited for Atlas to make his way to the surface again.
When he stuck his head out of the water, crawling onto the rock, Atlas matched eyes with the great sea snake, who at that moment, cracked the shell of the mollusk between it's teeth, and rolled the pulsing mussel out on to the top of the rock.

Atlas stared at the mussel, and then at the Ogopogo, then slank back into the water.

The sea snake waited.

In a mad splash, Atlas popped up out of the water, getting his entire body onto the rock, scrambling to the top.  He'd never used his legs before, and they scraped and scratched against the rocks face, while his arms worked to pull him up, and his tail pushed against the granite slab, giving him the balance and base he needed to force himself to the top, and open his mouth to devour the mussel.

But it wriggled away from him and fell into the water.

Dumbfounded, Atlas momentarily just stared after his evasive meal, then finally dove for it, catching it on the way to the bottom.

The Ogopogo felt his lips curl, and caught himself smiling at Atlas' efforts.
But before he would allow himself a father's pride, he cracked another shell, rolled out the mussel from within, and waited for round two.
