When the hard-shelled nautiloids evolved to abandon their shells to avoid biosonar detection, beaked whales refined their biosonar to echolocate the internal structures of the soft-bodied squid--which then developed survival countermeasures including camouflage, shape-shifting, and ink-cloud diversions. Millennium by millennium, the beaked whales improved their sonar to defeat these escape mechanisms and chase the squid deeper into the canyon. This evolutionary pursuit-and-escape minuet between squid and beaked whales continued for thousands of generations, until the whales could hunt squid at depths of a mile or more—deeper than any other predator.
