The theme today for Cephalopod Awareness Week is fossils so the 12yo is declaring Orthoceras regulare Appreciation Day! These cone shaped nautiloid cephalopods (who seemingly forgot to roll up in a spiral like their cousins) lived in the Middle Ordovician 470 to 458 Million Years ago.

I missed #KrakenDay yesterday on account of belatedly celebrating Squittleday, so today in honor of "all the fantastical cephalopods of myth, movies, literature and legend" here is How To Draw An Octopus Merperson

The Southern Sand Octopus (Octopus kaurna) is a lanky octopus that is an expert in burrowing under the sand.

They use their siphon to jet water into the sand to fluidize it, then they start digging and pull themselves in. Then use their long arms to make a hole so they can breathe.

A Southern Sand Octopus (Octopus kaurna) burrowing into the sand next to a small sea plant. Its head and prolate spheroid shaped mantle are completely out of the sand, but its arms are all mixed up in the sand. The mantle is partially inflated and light orange. Its head and arms are dark orange. The arms are long and thin, and you can see the double rows of suckers on the arms. The rows of suckers are offset from each other.A Southern Sand Octopus (Octopus kaurna) sitting among small rocks on the sea floor. It has long thin arms that are just messily on the ground, mostly to the right. On arm in front is raised a bit and turned so you can see its double rows on interlocking suckers. The octopus is dark orange and has a thin, teardrop shaped mantle.A Southern Sand Octopus (Octopus kaurna) burrowing into the sand. The photo is taken from behind. The mantle is long and thin, but partly inflated. Most of its arms and head are not visible, partly due to the cloud of sand it is creating. It is mostly orange but the bottom of the mantle is white.A Southern Sand Octopus (Octopus kaurna) sitting on the sea floor. Its lower body appears to be buried but its head, mantle and arms are still mostly above the sand. Its arms are all curled and in a tangled pile next to its head. Its offset double row of suckers are are clearly visible. Its mantle is partially inflated, giving it a shape like a skinny lemon. The octopus is orange except for the bottom of its mantle that is white.

Happy belated #Squittleday, October 10th, on which we celebrate the ten-armed squid and cuttlefish! I was in the woods yesterday, but here a few favorites from the archives 🦑🥂 (anyone spot the alt text Shakespeare reference?)

The big-eye jellyhead (Inopinoteuthis magna), in addition to having a very silly name, is thought to be the largest species of cirrate octopus, a group of octopus with small tendrils called cirri, fins and an internal shell.

One specimen of this species had a total length of 1.7 m.

on the shores of Japan visitors come to see the blue glow and they are a boon to fishermen who collect the dying squid. Thea adorable Bobtail squid (actually, not a squid, but a cephalopod of order Sepiolida, closer to cuttlefish) are also called dumpling squid or stubby squid.

thanks to bioluminescent organs and its unique slow oxygen metabolism. Its eyes are disproportionately large. Despite its name it feeds on detritus, not blood. The firefly squid (Watasenia scintillans), also called sparkling enope squid or hotaru-ika in Japan live at depth (200 to 400 m) and they

My linocut print shows the firefly squid against a white background on the left side of the square so you can see the whole animal and then its reflection is shown on the right against dark blue so you can see how its bioluminescence would appear underwater with fluorescent blue spots. On the left it’s a deep orange-pink squid with large gold and black eye. On the right you can see its body is covered with bright blue spots. The print is 8" x 8" (20.3 cm x 20.3 cm) on white Japanese kozo (or mulberry) paper.

October 10 is Squid and Cuttlefish Awareness Day - or Squittle Day for the tentacular cephalopods, so enjoy my linocuts of a vampire squid, firefly squid & bobtail squid! The vampire squid (Vampyroteuthis infernalis)or the ‘vampire squid from hell’ is a small deep sea cephalopod found throughout

This is a hand-carved and hand-printed lino block print on delicate ivory Japanese mulberry paper, 9.25” x 12.5” of a vampire squid (Vampyroteuthis infernalis). The ‘vampire squid from hell’ is a small deep sea cephalopod found throughout temperate and tropical oceans with two long retractile filaments, located between the first two pairs of arms on its dorsal side, unlike either octopuses or squids. The squid is upside down with purple head and yellow tent like areas between its legs. The filaments arc around above against the blue background.
