Stylephorus chordatus, a tube-eye of the family Stylephoridae, is a mesopelagic and bathypelagic species with eyes modified to detect the slightest traces of light. This species feeds by sucking plankton (copepods) into its small mouth opening and up its long snout. It makes daily journeys through the water column, with the plankton it feeds upon, closer to the surface at night and deeper by day. It swims oriented straight up and down in the water column. This individual was captured in a trawl between 640 and 1000 meters depth in the Gulf of Mexico, 2007.
