Need a reminder that our ocean is full of unusual animals? Look no further than the glass octopus.
The glass octopus (Vitreledonella richardi) is a very rarely seen cephalopod found in tropical and subtropical waters around the world. The species gets its name from its nearly-transparent body—you can see straight through to the optic nerve, eyes and digestive tract. These octopuses mostly live in the aphotic zone, meaning deep waters where sunlight doesn’t reach, at around 3,000 feet. They can grow to about 1.5 long and are estimated to live about 2-5 years.
The glass octopus lives in deep, hard-to-reach places, so there is much we don’t know about this translucent and luminescent cephalopod. So far, there have only been a few sightings and a few specimens recovered from the gut contents of their predators.
