The Flamboyant doesn't swim and hover midwater like other cuttlefish. Instead, it crawls on the seafloor like an octopus.
This behavior is related to its reduced cuttlebone. A cuttlebone is the "skeleton" of a cuttlefish, intermediate between the robust shell of a nautilus and the slender pen of a squid. It's internal like the pen, but calcified and chambered like the nautilus shell. These chambers are full of gas and liquid, the relative concentrations of which the animal can alter in order to change its buoyancy.
Because of its extra-small cuttlebone, the Flamboyant has a hard time with buoyancy. It can't swim for very long without sinking to the bottom. But what it lacks in buoyancy, it makes up in flambuoyancy!
I want to be an octopus, I want it so bad.
Not only does it crawl around the bottom like an octopus, it's
Here is a truly rad video with some fun facts about the Flamboyant. The only correction I would offer is that the bite of this cuttlefish isn't known to be venomous. Rather, toxin is found in its muscle tissue, making it more like a pufferfish than a blue-ringed octopus: poisonous, not venomous.
