Two new members of the mysterious barreleyes family of fish have been described.  The researchers have dubbed these new species the gray and black mirrorbelly, Monacoa niger and Monacoa griseus. The mirrorbellies are typically found at depths between 400 to 700 meters, part of the ocean’s twilight zone.
