October 11 – Kraken Day

Posted October 11, 2018


Zeus, in Clash of the Titans, gave this order to unleash the gigantic sea monster known as the Kraken. The Kraken also appeared in the movie The Pirates of the Caribbean: Dead 
Man's Chest, and it swallowed Captain Jack Sparrow and his entire ship whole!


For as long as there have been humans living near oceans, probably, there has been fear of gigantic tentacled monsters. That's probably because every once in a while a giant squid washes ashore...



By the way, if you ever see a photo like the one below, it's likely fake (this one is definitely fake):


You see, people will take a real photo of a giant squid, like the first one below, of a gigantic 30-foot squid, and they will drop it into a crowd scene (the second one below), maybe from a sand castle building event, and they then proudly proclaim that a 160-foot squid washed up!




The longest giant squid ever measured is 43 feet long, but of course humans can imagine bigger. And scarier: a giant cephalopod that hunts us, that wants revenge or that loves to attack anything from ships and people to buildings and bridges.



Today we celebrate the tentacled creatures or cephalopods of myth and legend, of story and movie. It's all a part of Cephalopod Awareness Week, which is celebrated every October 8 to 12. 

The Kraken is joined by other mythical cephalopods: There's the enormous octopus Akkorokamui, from Ainu (Japanese) folklore. There's Kanaloa, an enormous squid (or octopus) in Hawaiian stories. And there's the Cecaelia, the octopus woman from Native American peoples such as the Tligit and the Nootka, who live in the Pacific Northwest, what is now Alaska or Western Canada.

October 10 – Squittle Day

Posted October 10, 2017

This is the third day of Cephalopod Awareness Days. 

We started with Octopus Day on the 8th (for all the 8-armed species), then moved onto Nautilus Night 
yesterday (for all the lesser-known cephalopods that are still alive today). 

Today is Squid and Cuttlefish Day - aka Squittle Day! It's on the 10th because squids and cuttlefish have two tentacles along with their 8 arms (and 2 + 8 = 10).

Tomorrow will be Kraken Day, for the mythical and fanstastical cephalopods of fiction and legend. 

And the next day will be Cephalofossil Day - because that day is also National Fossil Day.

Tentacular species!

Cephalopods are probably the world's smartest invertebrates. (Invertebrates are animals without backbones.) As complex as bee communication is, as amazing as ant societies are, insects and spiders do not show the problem-solving abilities that cuttlefish, squid, and octopuses (or octopi) demonstrate. Maybe it's just a matter of having bigger brains - cuttlefish and octopi have the highest brain-to-body mass ratios of all invertebrates.

Squid have long, torpedo-shaped bodies that are able to shoot through the water at around 15 mile per hour (24 km/hr) - and some squid have been clocked at an astounding 22 mph (36 km/hr)! That makes them one of the fastest invertebrates in the world.








Cuttlefish are masters of camouflage. These might be the same species, despite their different coloring:





Long-ago ancestors of modern squid and cuttlefish had external shells. But these creatures evolved to have stiff supporting structures inside their mantles - a bit more like internal skeletons that vertebrates have. Squid have "pens" and cuttlefish have "cuttlebones."






Learn more about the cuttlefish's camouflage ability here. And here is a long documentary about cuttlefish.
