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. Colossal Squid vs. Sperm Whale, John Meszaros, nocturnalsea.
Colossal squid vs huge toothfish – clash of the deep-sea titans | New Scientist
Squid 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 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.
Colossal Eyes Give Giant Squids an Advantage When Fighting Sperm Whales
The colossal squid Mesonychoteuthis hamiltoni , sometimes called the Antarctic squid or giant cranch squid , is believed to be the largest squid species in terms of mass. It is the only known member of the genus Mesonychoteuthis. Unlike the giant squid , whose arms and tentacles have only suckers lined with small teeth, the colossal squid's limbs are also equipped with sharp hooks: some swivelling, others three-pointed.
