Itâs squid mating season! đŚ I found this squid egg mop washed ashore, and the video is another I found in the water at low tide attached to a rock in the South Shore of Boston.
Squid donât guard their eggs. Once laid, the parents die off (semelparity), and the capsules are left to develop on their own, anchored to sand, rock, or other egg mops nearby. The gelatinous casing protects the embryos from bacteria and predators while still letting oxygen through. If you look closely at the picture, you can see hundreds of miniature squid with eyes!! đ Storms and strong currents can tear a spawning bed loose and wash clusters like this one onto the beach. đ
Depending on species and water temperature, embryos develop for a few weeks to a couple months inside the capsule. When theyâre ready, hatchlings emerge as fully formed miniature squid, called paralarvae, just millimeters long. They hatch already swimming, jetting, and hunting tiny plankton, and from day one theyâre on their own.
This one had washed ashore, so I gently carried it back into the water. Embryos need to stay submerged to keep developing â once stranded on dry sand theyâll dehydrate and die pretty quickly. If you find one out of the water, the kindest thing to do is return it to the sea (no need to touch the delicate finger tips more than necessary, just cup it and carry it back).
**This was a great moment to talk to my kids about gentle hands & being respectful to all animals. Lately, Iâve watched kids fling jellyfish down rock slides & toss them in the air â not out of cruelty, but they do need guidance & education. The ocean is home to all of this, not a toy box. A simple rule helps: look, donât grab; and if somethingâs stranded, ask an adult before touching it. Curiosity is wonderful â itâs how kids become the next generation of people who care about this stuff. We just want to point it in a direction that keeps the animals (and little hands) safe.
