““waters, and even some that leave the water altogether. The Japanese flying squid (Todarodes pacificus) can take to the air like a flying fish; it builds up speed underwater and then launches itself out of the water and glides until reentry. Flying squid have been observed to cover distances as long as 100 feet above the surface, presumably to avoid predators, or utilizing jet-propelled aerial locomotion to save energy as they migrate. It has been shown that penguins, sea lions, and dolphins save energy by performing low-level leaps over the surface as they swim, which enables them to momentarily avoid the resistance of water and, concurrently, grab a breath of air. Squid don’t need a breath of air—they breathe water through their gills, like fishes—but several squid species can and do leave the water; mariners in all oceans occasionally find little squid on the decks after a night of sailing. The Humboldt squid (Dosidicus) has also been observed to get itself airborne; if a hundred-pound, ink-squirting, beak-snapping squid lands on your deck, you might have a bit of a problem.””
