Wanna Cuttle? #cephdays #ceph14


thIn 1831, a 22-year-old scientist named Charles Darwin boarded the science vessel H.M.S. Beagle (a refitted 10-gun war sloop), and departed England bound for the Canary Islands and South America. Throughout the 5-year voyage, Darwin kept notebooks and recorded his observations. These he would put in the weighty five-volume set~ The Zoology of the Voyage of H.M.S. Beagle (later renamed The Voyage of the Beagle). In one entry, he mentions the unique qualities of cuttlefish:

“This cuttle-fish displayed its chameleon-like power both during the act of swimming and whilst remaining stationary at the bottom. I was much amused by the various arts to escape detection used by one individual, which seemed fully aware that I was watching it. Remaining for a time motionless, it would then stealthily advance an inch or two, like a cat after a mouse; sometimes changing its colour: it thus proceeded, till having gained a deeper part, it darted away, leaving a dusky train of ink to hide the hole into which it had crawled.”
~Journal of Researches, HMS Beagle Voyage, Jan. 1832

I just love cuttlefish and octopuses. I’m in awe of these creatures just like Charles Darwin was. I even have a Pinterest board just for cephalopods. lol What can I say? I’m a nerdy girl. But I’m not alone in my mollusk admiration. Today sets off International Cephalopod Awareness Days. No kidding.

October 8th through 12th are International Cephalopod Awareness Days.8

Ω
  October 8 ~ Octopus Day. The 8th to honor those  with 8 arms.

Ω  October 9 ~ Nautilus Night. For the creatures of the Golden Mean
Ω  October 10 ~ Squid/Cuttlefish Day. #Squidturday for species with tentacles.
Ω  October 11 ~ Myths and Legends Day. For Kraken et al
Ω  October 12 ~ Fossil Day. Who went extinct?

Cephalopods are a class of mollusk that includes cuttlefish, octopuses, squids, and nautilus. Would you believe they’re represented in the fossil record dating back 500 million years?

Cephalopod~ from the Greek kephale for head and pod which comes from pous for feet. Head feet? As you might have guessed, I get a kick out of breaking words down to their origins. I have more in honor of the day:

Cuttlefish~ from Old English cudele and Middle Low German küdel , both meaning container or pocket. From the Old Norse koddi meaning cushion or testicle. So that’s where Old English codd pieces get their name.

Octopus~ from the Greek oktṓpous — literally eight-footed —octo for eight, pous for feet.

Squid~ possibly from late Middle English squirten or to squirt. Squid as we know it could be a sailors’ variant of squirt in reference to the ink the animal squirts out. No one knows for sure.

  • There are about 300 known species of octopuses alive today. They are divided into two groups: Cirrina (deep sea species with fins on their heads) and Incirrina (the species we typically envision when we think of octopuses. No fins).
  • Octopuses exhibit remarkable skill at problem solving and are considered the smartest of all invertebrates.
  • There are over 100 known species of cuttlefish and they vary in size from just a few inches to over three feet in length. The giant cuttlefish can weigh more than 20 pounds.
  • As far as scientists can tell, octopuses are colorblind, but they can see polarized light. So can cuttlefish and squid. What’s that exactly? Light has properties of both particles and electromagnetic waves and in wave form has the ability to vibrate in multiple directions. Our eyes see light like this.  Polarized light has these light waves occurring in a single plane rather than multiple directions. The benefit to these hunters of the sea is that nothing can hide from them. That’s my best early-morning explanation. lol And now I’ll go refill my coffee cup.
  • Octopuses and cuttlefish have specialized epidermis cells called chromatophores that enable them to blend into their surroundings by changing the appearance of their skin. In the video clips below they even appear to take on textures on the sea floor.
  • An octopus doesn’t have tentacles, it has arms. Tentacles are longer than arms and generally have suckers  at their tips only. Think squid.
  • When threatened, cephalopods release ink in a cloud to confuses predators and allows time for escape. Like throwing down a smoke bomb!  This ink is sepia. Historically it was used in ink pens. Today cephalopod ink is used medicinally (it’s actually toxic to tumor cells). The ink is also used as a food coloring. That spooky McDonald’s burger with the black bun comes to mind. I wonder if cephalopod ink is an ingredient?
