Glowing Bamboo Coral

From glowing coral to shrimp that vomit light-making chemicals, seafloor creatures can create quite the flashy visual show, according to researchers who traveled into the inky depths of the Caribbean Sea to investigate the oddballs. Even so, the researchers reported that seafloor creatures are less flashy than their open-ocean cousins. In the open sea, an estimated 90 percent of organisms have the capacity to glow, compared with a paltry 10-20 percent of seafloor dwellers. This glowing bamboo coral (Isidella sp.) was found on the Caribbean seafloor.
