If they succeed, they will have helped usher in the world’s newest marine model organism.Ĭuttlefish embryos circulate within a soda-bottle incubator designed by Bret Grasse, manager of cephalopod operations at the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts. This is one of several low-tech innovations the team has implemented toward mass producing cephalopods as lab animals. Some cephalopod parents oxygenate their eggs until they hatch, but Grasse developed the soda bottle incubator to automate the task, freeing the parents up to produce the next batch of eggs. Air piped into each bottle keeps translucent eggs the size of raisins oscillating inside. What at first looks like misplaced plastic bottles inside some tanks turn out to be old Coke bottles, purposefully placed mid-tank to incubate cephalopod eggs. A constant gurgle of fresh Cape Cod seawater originating from an adjacent inlet trickles through a network of pipes adding to a sense of chaos in the spacious but tightly packed wet lab. Led by squid wizard Bret Grasse, the workers here at MBL’s Marine Resources Center are attempting to master the science of rearing cephalopods-a group that includes squid, cuttlefish, and octopuses-in captivity. They check water quality, administer food, jot down notes, and otherwise go about the business of transforming the landscape of marine biological research. Just past a “squid sign-out” sheet, on the ground floor of a stately brick building at the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, a handful of people in lab coats shimmy between rows of microwave-sized tanks.

Scientists at the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, are attempting to master the art of culturing cephalopods, including these flamboyant cuttlefish embryos, as they develop a new marine model organism.
