Trimma nasa
''Trimma nasa'', commonly called the nasal dwarfgoby or nasal pygmy goby, is a species of goby from the Western Pacific. They are small fish, averaging at around in length. They are bright orange and transparent yellow in life, with a white stripe running down from between the eyes to the upper lip and a dark brown spot at the base of the tail fin. They are usually found in large schools in the sloping or vertical drop-offs at coral reef edges.
==Taxonomy==
''Trimma nasa'' belongs to the ''Trimma nasa'' species group of the dwarfgoby genus ''Trimma''. It is included in the true goby subfamily Gobiinae in the goby family Gobiidae. It was first recognized as a separate species in 2005 by the ichthyologist Richard Winterbottom. The type specimens were collected from Siquijor Island in the Philippines. Though specimens of this species have been recovered previously, they were misidentified with Griffiths' dwarfgoby (''Trimma griffithsi'').〔
The generic name ''Trimma'' is derived from Greek τρίμματος (''trimmatos'', "something crushed"). The specific name is derived from English "nasal ()" in reference to the stripe on the snout.〔
