The International Cephalopod Awareness Days are celebrated since about 2007 and are supposedly an initiative from The Octopus News Magazine Online.
The International Cephalopod Awareness Days consist of several sub-holidays, which are:
- October 8 – Octopus Day, which means all the eight-armed species. Because “octo” is latin for “eight”.
- October 9 – Nautilus Night, a time for all the lesser-known extant cephalopods
- October 10 – Cuttlefish Day covering the tentacular species
- October 11 – Kraken Day, for all the fantastical cephalopods of movies, literature and legend.
- October 12 – Fossil Day for all those cephalopds who are o longer here to celebrate with us.
