Squids have excellent eyesight, a keen sense of smell, and the ability to squirt jets of dark ink that mask their escape. But these skills provide little protection against toothed whales, like the sperm whale, which hunt them ruthlessly and easily. How the whales manage to subdue such able prey has been a mystery. One hypothesis, proposed more than 20 years ago, speculated that the whales used powerful ultrasound shrieks to knock their squid prey senseless before scooping them up. Like bats and dolphins, some whales use ultrasonic clicks to find prey and navigate. While controversial among scientists, the idea has become a part of whale lore, adding to the mystery that surrounds the clandestine struggles between leviathan and squids that occur within the ocean depths every day.

Sperm whales are named after the spermaceti oil wax that they produce in the spermaceti organ located in their head. It is because of this oil that man hunted the sperm whales, going after the prized spermaceti oil that was used to make smokeless candles during the 19 th century. Sperm whales are one of the deepest diving whales, they usually dive hundreds of meters to find their food but have been recorded at depths of over m which is phenomenal. Sperm whales eat prey found on or near the ocean bottom, squid is their main diet but they also eat sharks and various bony fish.
By SciTechDaily March 19, The only benefit of such huge eyes in the murky depths of the oceans is to spot enormous shapes, such as the ones of sperm whales. The findings were published in the journal Current Biology and they could explain the equally large eyes of the ichthyosaurs, which could have helped it evade the even larger pliosaurs.

The threat of killer whales could be why societies of sperm whales in the Atlantic and Pacific differ so much, researchers say. The sperm whale, the largest toothed whale, possesses the largest brain of any organism on Earth. These leviathans mostly live on giant squid and other creatures of the deep, pursuing them with the most powerful natural sonar known.
