I guess not. In 1999, a study led by Peter Herring found evidence that noted that shrimp eyes from heavily visited vents were opaque because the light-sensing tissues had been destroyed. The potential culprit? Large megawatt lights on submersibles. A new study, soon to be published in the UK’s Marine Biological Association journal finds these effects may not be detrimental to shrimp populations. According to the BBC news, the new study finds that the TAG vent site no population change was detectable when data from 1994 and 2000 were compared. This suggests that the shrimp can rely on other sensory systems to survive.
