Opisthoproctidae

The Pacific barreleye fish (Macropinna) is a genus of ray-finned fish belonging to Opisthoproctidae, the barreleye family. It contains one species, M. microstoma. It is recognized for a highly unusual transparent, fluid-filled shield on its head, through which the lenses of its eyes can be seen. It was originally believed that the tubular eyes of this fish were fixed in place, offering only tunnel vision above its head. However, in 2008, scientists discovered that its eyes were able to rotate both up and forward with its transparent dome. This feature allows for M. microstoma to observe prey w

Barreleyes, also known as spookfish (a name also applied to several species of chimaera), are small deep-sea argentiniform fish comprising the family Opisthoproctidae found in tropical-to-temperate waters of the Atlantic, Pacific, and Indian Oceans.
