Frunalian

Frunalians are a humanoid race with several insect-like characteristics. Though it is unclear whether or not the Frunalians are members of the Federation, many do choose to join Starfleet.

Frunalian physiology allows the use of both eyes simultaneously, and the structure of their brain allows them to process both sets of information taken in as well.

At some point in life, all Frunalians undergo "The Shift", a period of metamorphosis. The age at which this is onset can vary a great deal.
