OCTOPUS or the cephalopod mollusc
Octopuses are some of the oldest and most impressive creatures on the planet. Their multiple arms (not tentacles) made them the stuff of monster legends, but they’re more human than you might expect.
In a (coco)nutshell
They are the first invertebrates (animals without backbone) to be seen using scavenged tools, such as shells and coconuts, to hide from potential predators.
a brain the size of a walnut
Despite their walnut sized brain, octopuses are highly intelligent, possibly more so than any other order of invertebrates.
Hide and seek
Octopuses are solitary and lack a shell, which leaves them quite vulnerable to other predators. The trick is, you have to spot them first.
ink master
If a clever predator does manage to spot the octopus, it buys time to get away by ejecting a cloud of black ink. Reduced visibility isn’t the ink’s only purpose, it also contains a substance that dulls a predator’s sense of smell, making the fleeing octopus harder to track.
the abyssal octopus a.k.a. the vampire squid This deep sea octopus is covered entirely with light-producing organs called photophores. These underwater strobe lights are capable of producing disorienting flashes of light for up to several minutes at a time.
multi-tasking deluxe
Two-thirds of an octopus’ neurons reside in its arms, not its head. This means one arm can work on opening a shellfish while the rest of the octopus is busy doing something else.
you can have my heart
Octopuses have three hearts. Two pump blood through each of the two gills, while the third pumps blood through the body.
a sucker for smelling
A common octopus has about 240 suction cup-like protrusions on each limb, and a particularly large sucker can hold up to 35 lbs. The suckers are also extremely sensitive; they can pick up subtle chemical signals and move individually, even folding in half in a pinching gesture.
BYE!
