Macropinna microstoma is the
only species of fish in the genus Macropinna, belonging to
Opisthoproctidae, the barreleye family. It is recognized for a highly
unusual transparent, fluid-filled dome on its head, through which the
lenses of its eyes can be seen.

The eyes have a barrel shape and can be rotated to point either forward
or straight up, looking through the fish's transparent dome. M.
microstoma has a tiny mouth and most of its body is covered with large
scales.

The fish normally hangs nearly motionless in the water, at a depth of
about 600 metres (2,000 ft) to 800 metres (2,600 ft), using its large
fins for stability and with its eyes directed upward. In the low light
conditions it is assumed the fish detects prey by its silhouette. MBARI
researchers Bruce Robison and Kim Reisenbichler observed that when prey
such as small fish and jellyfish are spotted, the eyes rotate like
binoculars, facing forward as it turns its body from a horizontal to a
vertical position to feed. Robison speculates that M. microstoma steals
food from siphonophores.

M. microstoma has been known to science since 1939, by Chapman, but is
not known to have been photographed alive until 2004. Old drawings do
not show the transparent dome, as it is usually destroyed when brought
up from the depths.
