Strawberry Squid…Forever

strawberrysquid2

The “Strawberry Squid” or Histioteuthis heteropsis is a deep-sea squid that is known for it’s resemblance to a strawberry and it’s mismatched eyes. It is also affectionately called the cock-eyed squid by it’s squid friends and a few marine biologists. Particularly after it’s had too many strawberry daiquiris 😉 Sorry, I couldn’t help myself…

Recently researchers at Duke University determined why the Strawberry Squid has a large, light colored eye that is angled upwards and a smaller, darker eye angled downwards. After analyzing hours (and hours) of underwater footage from the Monterey Bay Aquarium Research Institute, Duke graduate student Kate Thomas determined that the larger eye evolved to detect marine life in the water column above it while the smaller eye evolved to detect bioluminescent light from marine life found below it. So one eye looking out for predators and one eye looking out for prey.

In the past, studying and observing organisms that inhabit the deeper parts of the ocean was challenging. But with the advent of remotely operated vehicles (ROV)  and and other related technology, researchers can get to know some of the odd fellows that populate the deep, deep sea. If you are curious about what MBARI finds at the bottom of the ocean, check out their YouTube channel: https://www.youtube.com/user/MBARIvideo. Another favorite is NOAA’s Ocean Exploration and Research YouTube channel: https://www.youtube.com/oceanexplorergov. And you thought YouTube was only good for watching cat videos.
