    Ommatokoita: Brief Summary
    provided by wikipedia

    Ommatokoita elongata is a 30 mm (1.2 in) long pinkish-white parasitic copepod, frequently found permanently attached to the corneas of the Greenland shark and Pacific sleeper shark. The parasites cause severe visual impairment, but it is thought that the sharks do not rely on keen eyesight for their survival. It was speculated that the copepod may be bioluminescent and thus form a mutualistic relationship with the shark by attracting prey, but this hypothesis has not been verified. It is the only species in the genus Ommatokoita.
