I’ve invented ‘The Knife-Wielding Tentacle'👍
Oh, those brilliant molluscs…
Fins up if you love sharks! There’s still a lot to learn about these fascinating, misunderstood creatures, but one thing we do know is that there’s a huge diversity of spectacular shark species gliding through our ocean.

Drone captures a whale opening its mouth to feed. That is a big mouth.
Fuck that

#TGIF! Time to wash the off the stink of the work week & get ready for the weekend!

Another cool video of a camouflaged octopus. When spotted, the octopus tries to impress the enemy by quickly changing color – mostly white (fear and aggressiveness)). It will also inflate itself to appear bigger, thus more frightening. How cool is that ?
As you may know by now, octopuses can control both their color (thanks to their chromatophores) and their skin structure. The size of their skin projections, called Papillae is controlled through muscular hydrostat.
A muscular hydrostat is a biological structure mainly made of muscles with little or no skeletal support, which can easily change shape to bend, extend, etc. Some other examples of muscular hydrostats are our tongue and an elephant’s trunk. This is how the octopus can appear smooth, bumpy or spiky at will.
This video is a close-up of the octopus’s papillae. You can clearly see the muscular hydrostats at work, amazing !
All good things must come to an end, and #CephalopodWeek is no exception. But take heart! Before we close out this celebration of some of the world’s most astonishing invertebrates, we’re highlighting some of great content that this event inspired.
Our colleagues at @sciencefriday explored both the biology and psychology of octopuses (not octopi!) in this video:
Meanwhile, the @montereybayaquarium Research Institute (MBARI) assembled a remarkable highlight reel of cephalopods from around the world:
