Lord of the Rock Pool

I found it when the tide was out, a small pool of life marooned in the rocks, a leftover from four hours ago, holding an octopus, two starfish and a crab captive in a watery cage. I stared into its shallow eye, past a milky cataract of cloud and saw smaller life dart and dash for cover in the threads of purple weed, fleeing from my finger as it stirred their heavens and sent terrifying whirlpools to lash their world. I lorded over this handful of bounty left by the sea, a subdued and captured pocket of its might, prodding and poking until I realized the blue ringed beauty of the octopus could kill me, with just one bite.
