A fish with a transparent head

Macropinna macrostoma (common name "barreleyes) can rotate its eyes to a vertical position; because its head is transparent, it can then look through its head to see predators or prey above itself without moving its body. The transparent head also protects the delicate eyes from the stinging cells of siphonophores, which probably are the primary prey for this fish.

The world is full of amazing adaptations.


  1. can there be prettier fish than this? i feel like wishing to transform into a fish if it meant to be like this :)
