Scypholanceola aestiva

A red Scypholanceola aestiva stares at the screen with large orange eyes.

Scypholanceola aestiva looks like an armored alien of the deep. It doesn’t have compound eyes like other hyperiids, but instead sees variations in light using reflective cups embedded in the exoskeleton on its head. This light detection works best with green wavelengths. Why would it want to see green light in the deep sea? It is most likely looking for signs of bioluminescence—bright green and blue flashes of light made by animals—that could signal that food or a predator is nearby.
