Despite this, they are equipped with a pair of large eyes which, rather than using lenses to focus light onto a retina, use parabolic mirrors a few millimetres across.〔(【引用サイトリンク】publisher=Encyclopædia Britannica )〕 It is thought that ''Gigantocypris'' uses these eyes to find sources of bioluminescence for it to prey on,〔 and it feeds upon copepods and small fish.〔 ==Species== The genus contains six species:〔 *''Gigantocypris agassizii'' G.
