Seventy percent of all ocean life lives within the rim of our continental shelf. Temperature has affected this part of the ocean the least, but it remains at the mercy of two things: ocean currents and increasing pollution. The ecology of the open ocean depends on a certain temperature range, and deviation brings great hardship for its residents. While tiny, delicious morsels ride the currents, they’re also accompanied by the scourge of the ocean – plastic. And overfishing is taking many pelagic species to the brink of extinction. But there is ingenuity in the deep blue realm. In some parts of the ocean, predators are teaming up to make the most of dwindling fish stocks. Oceanic whitetip sharks and pilot whales now combine forces to hunt. The results are spectacular.
