Hunting one down with merely the knife and floaties I bring on every expedition is a daunting task indeed. Whales are nearly impossible to catch in their own habitat. Though we are both mammals, their swimming ability is far more advanced than ours. Many times I've spotted a whale and leapt into the ocean only to lose it in the ensuing chase.
Thus, the primary way a whale is useful to a survivalist is if it's already beached. Whales generally perish in prolonged battles with giant squid (see below for a helpful illustration tattooed on some dude's arm) and sometimes wash up on land in the turbulent hours preceding a storm. But Poseidon is fickle. I urge you not to spend your final minutes 'neath the darkening sky waiting for him to deliver you a whale. Pursue a land beast, but keep an eye to the sea. Hope is the survivalist's most powerful tool.
