My Future’s So Bright…


The future doesn’t look so hot for most citizens of the oceans. Ocean acidification, overfishing, marine debris, and many other stressors are taking a toll on aquatic living. However one group appears to be gaming the system and actually proliferating in these days of algal blooms and coral bleaching. Hail the mighty Cephalopods! According to a recent study by researchers from the Environment Institute at the University of Adelaide in Australia, cephalopod (squid, cuttlefish, and octopus) populations are booming around the globe. In the May 2016 issue of Current Biology, the researchers report on their findings on population health trends for 35 species/ genera and six families of cephalopods through the analysis of six decades of global fisheries data. The researchers believe that short life spans, rapid growth, and high adaptability appear to be the recipe for success for these curious creatures of the sea. In addition, the crash of certain fish stocks appear to reduce predation and competition for cephalopods. While the current situation appears to be rosy, ocean acidification and overfishing of cephalopod stocks loom in the horizon like the clouds of an incoming storm. Boo!!!

About This Illustration: A watercolor painting of three cool cephalopods (from left to right: squid, octopus, and cuttlefish). The song “My Future’s So Bright I Gotta Wear Shades” by Timbuck 3 was the inspiration for this illustration. For those of you who do not know this great little ditty, check this out:
