Redeye

Redeyes inhabit clear-water streams with an abundance of shoals and are usually confined to headwater sections.

This is probably less of a barrier to mesopelagic species such as lanternfish (Lampanyctodes hectoris), redeye (Etrumeus whiteheadi) or gobies (Sufflogobius bibarbatus), all of which are capable of more extensive vertical migration than the small epipelagic fish.

The Common Redeye (Matapa aria Moore) is much smaller (wingspan: 40–55 mm), plain brown without any markings, but as in the Giant Redeye its eyes are red.
