For the delicate monarch 1, it may as well be a trip to the moon. And yet somehow they do it, their tiny bodies attuned 2 to a seasonal 3 sundial and resonating to the invisible signature of the earth's core--its magnetic field. Around the planet, animals, large and small, are responding to these forces as palpable to them as they are indecipherable to us.
And far out to sea the largest brains on earth, fix on these mysterious cues. The male sperm 4 whale, a creature of superlatives. It is the largest toothed predator 5 alive today, weighing up to 50 tons. It dives deeper and faster than any other whale and it undertakes some of the greatest journeys. In a lifetime, this whale may log a million nautical 6 miles. The males often circle the Arctic to feast. But for the species to survive, their paths must intersect with the females' own astounding 7 journeys, coursing warmer waters. Many will meet in the Azores--nine tiny islands where clashing currents create an explosion of life.
A mother ushers 8 her newborn calf 9 into coastal 10 waters, guided by sun, sea currents and perhaps even magnetic sensors 11 in her brain. She also navigates 12 by sonar, bouncing her clicks and creaks off the sea floor, some of the loudest sounds made by any creature on earth.
