where the ocean pretends to be safe and the sharks pretend to be elsewhere
means The parts of a body of water that are not deep, where the bottom lies close beneath the surface.
from From 'shallow,' an Old English word (sċeald, meaning shallow or hollow) that drifted into Middle English as 'shalow' — the noun 'shallows' simply pluralizes the adjective into a place, the way 'narrows' names a tight stretch of water. The deeper roots are murky, possibly tangled with 'shoal,' its near-twin for a low, sandy patch.
