Deep-sea jellies are as diverse as they are beautiful!
Steve Haddock and
his collaborators study these animals because the many remarkable
shapes, sizes, colors, and bioluminescence capabilities can help in
understanding evolution in the deep-sea, the chemical processes involved
in bioluminescence, predator-prey interactions, and biodiversity in the
This Solmissus jelly is probably its deep purple color because of it’s prey—in this case, another purple jelly!
undescribed species of hydromedusa - Tetrorchis, shows pink pigmentation
due to absorbance, and rainbow iridescence due to the thin-film effect
of its tissue acting on white incident light from the ROV.
undescribed physonect, called the galaxy siphonophore by Haddock and
his collaborators, is one of the more spectacular of the deep-living
species observed this week on the R/V Western Flyer. It is often found
in this spiral shape, casting its many tentacles all around like a
spider in its web.
