Lethops connectens, the Halfblind goby, is a species of marine goby native to the eastern Pacific Ocean from central California, USA to Baja California, Mexico where they inhabit kelp forests. The adults hide amongst the stones and holdfasts at the bottom while the juveniles form schools in the canopy. This species can reach a length of 6.4 centimetres (2.5 in) TL. Like the name suggests, the eyes of L. connectens are highly reduced. This species is the only known member of its genus.
