🏺 I submit the funniest #Minoan-linked octopus image ever - seen this year on the inside of one of the toilet cubicles at Phaistos 🐙

photo showing inside of a white toilet door with handle and lock, above is a two-pronged coat hook which has been drawn around to make it look like an octopus

Closeup of the Octopus drawing, showing six curled tentacles added complete with suckers; someone seems to have later put the date 2020, a heart and some letters.

From their three hearts to their doughnut-shaped brains, octopuses are fascinating creatures that are also biologically wired to die after they reproduce. We spoke with cephalopod expert Z. Yan Wang to learn more about octopus death spirals and to answer listener questions for Cephalopod Week!

Blue button jellies float on the waters surface. They’re related to true jellies, but they’ve got a dry top that feels a bit like a fingernail, and is filled with air-trapping chambers to keep the jelly above the waves This float also means they slide on the water like hockey pucks 🏒

Coconut Octopuses (Amphioctopus marginatus) are known to use tools. They will carry around shells in order to deploy them as a mobile shelter. It's nice to have some armour when you're a soft and squishy mollusk They also are known to sometimes walk around on two limbs. Take that Plato! #OCTOtober

A Coconut Octopus (Amphioctopus marginatus) sitting in a horizontal bivalve shell on the sea floor, and it is lifting the top half of the shell with one arm. The octopus looks very annoyed, and is staring at the camera. The octopus is a dark brownish red, with light orange on the bottom of its arms and white suckers. The inside of the shell is white, and the outside of the shell has dark red or orange stripes alternating with white ridges.

A Coconut Octopus (Amphioctopus marginatus) inside a glass bottle trying to pull in a crab it has caught, but the crab is too big. The octopus has its arms outstretched and grabbing the sides of the bottle. The octopus is off white with some dark brown through its eyes. A lot of its suckers have a light blue tinge. There is a bivalve shell in the bottle. The crab is larger than the octopus. It appears to have a crack in its shell, probably where the octopus bit it. It is facing away from the camera. Its left arms and a small part of its body are pulled into the bottle. It has a mottled batter on its body with some blue at the ends of its arms. The sea floor is sandy.

The suckers are clearly visible and the octopus is giving puppy dog eyes. The rest of its arms and body is in the jar.

A Coconut Octopus (Amphioctopus marginatus trying to leave its collection of shells for a larger shell, which contains another coconut octopus. The first octopus is exposed, and is straddling between the two sets of shells. The original set appears to be three, smallish shells. Two arms are reaching into the new shell. The octopus is purple, with little beige bits breaking up the purple. Its sucked are visible. Its mantle is round. The second octopus is is sitting in two, large mismatched shells. It is quite snug, with its suckers holding on to both shells. It is purple, with a lavender colour around the eyes and white around the suckers.

Blue-ringed octopuses (genus Hapalochlaena) are the only cephalopod whose venomous bite is potent enough to kill a human. However, they are docile and won't bite unless provoked or hunting. So keep your distance and don't make them feel threatened or be a crustacean and you'll be safe. #OCTOtober

A Greater Blue-ringed Octopus (Hapalochlaena lunulata) swimming against a black background. Its mantle is relatively thin and the tip gets much thinner. The end of the mantle is out of focus. The octopus is looking at the camera, and it appears to be moving to the upper right, as most of its arms are trailing in that direction. One arms is going back and another is in front of its face and curving around. The arms have two rows of suckers that are offset. The octopus is yellow with many blue iridescent rings.

A photo of a southern blue-ringed octopus (Hapalochlaena maculosa) striking a pose. It is leaning to the left (camera's left), with left arm raised up and with half of it curled, and another one of it's left arms pointing left and with a quarter of it curled. The octopus is a pale brown-yellow with black patches with iridescent blue rings in the centre.

A photo of a Blue-lined Octopus (Hapalochlaena fasciata) on the sandy sea floor among sea grass. The octopus appears to be moving, with its arms curled backwards. Its mantle is tear drop shaped or like a milkweed seed pod, gong to a rounded point. It is has its papillae raised. It is a pale yellow colour, with black or dark brown areas. Inside the dark areas, are iridescent blue circles or lines.

Today is #WorldOctopusDay 🐙 Did you know that octopuses have blue blood? This graphic looks at what makes it blue, as well as other blood colours seen in different organisms: wp.me/p4aPLT-Fc #ChemSky 🧪

Infographic on the chemistry of the colours of blood. Human blood is red due to haemoglobin, which is also red when deoxygenated - not blue! Spiders, crustaceans, and molluscs including octopuses and squid have blue blood due to haemocyanin, which contains copper instead of iron. When deoxygenated, haemocyanin is colourless. Some segmented worms, some leeches and some marines worms have green blood due to chlorocruorin, which is light green when deoxygenated. Marine worms including peanut worms, penis worms and brachiopods have purple blood due to haemerythrin, which is colourless when deoxygenated.

Mimic Octopuses (Thaumoctopus mimicus) are known for the fact they mimic several different kinds of animals, including sea snakes, flatfish, lionfish, anemones and more. They also seem to choose their disguise based on the predator they are trying to fool. #OCTOtober

A Mimic Octopus (Thaumoctopus mimicus) sityting on the sea floor. Its mantle is hanging behind it and its arms are holding it up and have the webbing partially inflated. It is facing forwards, towards the camera and its two fleshy horns above each eye are flopping to the left, pushed by the current, making the octopus look rather silly. Its arms are also being pushed left. The sea floor is a grey sand with many small rocks.

A Mimic Octopus (Thaumoctopus mimicus) stick out of the sand with an interesting pose. It is some of standing up, with most of its arms going straight down all oriented sucker forward, its mantle hanging behind, and its eyes on top. Its two centre arms, which are on top on the outside in this pose, go out and curve back forming a sort of hood shape. It is unclear why the octopus is in this pose or if it is trying to mimic something. The octopus is brown with some white, and white on the underside of its arms. The arms have two rows of suckers in an offset zig-zag pattern. The sand is greyish.

The Māori octopus (Macroctopus maorum) is one of the largest octopus species found in New Zealand and Australian waters. They also have arms that are long even for a large octopus. They have a max mantle length of 30 cm, but their longest pair of arms can have an arm span of over 3 m! #OCTOtober

A close up of a Maori Octopus (Macroctopus maorum) focused on its head. It has dark red and bumpy, wrinkly skin skin. One of its eyes is visible and is staring directly at the camera, making it look as if it has a judgmental expression.

A Maori octopus (Macroctopus maorum) sitting in among seaweed and extending its long arm at the camera. The seaweed looks like a bush, and its probably attached to a rock that the octopus is sitting on. The octopus is partially concealed, with its head and part of its mantle sticking out. The arm is rather long, although it might look a bit longer from how the camera was set up. It extends from the seaweed, curving down, then curving up while twisting, then going back down and then turning right and then steeply up. The tuckers are clearly visible as they are facing the camera at the end. They are cream coloured, contrasting with the brown of the rest of the octopus. There are two rows of offset suckers, and they are appear to have a brown rim with little fringes. There is not great visibility in the water in the background, but some pillars are visible in the background, possible part of a pier.

A Maori octopus (Macroctopus maorum) sitting among some rocks. It is partially between a gap between to rocks, and it is facing into the gap and away from the camera. The octopus has its papillae raised, so its mantle and head look very bumpy. It has yellow eyes. It has a dark purple colour on its mantle and head, with its arms being a mix of purple and white, with white spots.

A Maori Octopus (Macroctopus maorum) on the seafloor. It is reaching towards the photographer, with two of them lifted up and curving back, exposing their suckers towards the camera. The two arms take a significant part of the photo, so they make it look like the octopus is trying to block the camera. The octopus is dark orange and has a wrinkly texture with lots of larger bumps. There are fish swimming in the background and the sea floor is covered in medium sized rocks.
