This translucent octopus is one of the weirdest octopi I think I’ve come across. You’d think it would be a deep sea creature, right? However, these guys hang out in the pelagic zone of the Indian and Pacific oceans so you’d have a good chance of spotting them if you ever went scuba diving in the open ocean. That is, if you’re used to spotting practically invisible creatures that measure only 90 mm in length. Ya know, I would assume that’s more of a learned skill… 
This fellow is called the Telescope Octopus (Amphitretus pelagicus) because of its strange tubular eyes. It’s the only (known) species that has them. Totally radical, bro.
