Today we have a special (but largely visual) treat: the pelagic octopus Vitrelladonella richardi. This cephalopod is “transparent, gelatinous, and almost colorless.”  Since they are not only transparent but also live in the deeper part of pelagic zone of the ocean (the portion which is near to neither the top nor the bottom) they are rarely seen and little is known about them.  The females are ovoviviparous and broods her eggs within her body.  Both genders are strongly bioluminescent and use light for hunting, communicating, and hiding (by mimicking the faint light from the surface they can become even more invisible).   Even if we don’t know a huge amount about these octopuses, we are privileged to have some amazing photographs of them, thanks to the new generation of submersibles and submersible drones, which are exploring the pelagic regions of the ocean.  Look at how exquisite and alien these octopuses appear!  It’s hard to believe we share the planet with such strange animals…
