Last season, there was a bustle of excitement on Hog Island when an egg case of longfin squid (Doryteuthis pealeii) washed ashore on the beach of Porthole cove. Squid attach their eggs to subtidal rocks (always underwater), and they hatch within a few weeks. When we discovered a washed-up mop, we submerged it in water in our touch tank, mimicking as best we could the natural cycle of egg case attachment. In a little over a week, the eggs started hatching! Hundreds upon hundreds of baby squid (each about 2 mm, smaller than a grain of rice) hatched and were released into Muscongus Bay. But before we released them, campers, FOHIs, and staff alike reveled in the sights of baby squid in the touch tank and under the microscope. Up close, you can even see the chromatophores (color-changing cells) of the squid expanding and contracting in and out!
What marine magic do you hope to see this summer on Hog Island?
