Images: Cold Comfort for Barnacles

WHOI researchers found these barnacle larvae, called cyprids, frozen into ice in January on the shores of Buzzards Bay, Mass. They were surprised to find that the larvae (at 1 millimeter long, about half the diameter of the head of a pin) could thaw out, swim, and develop into normal adults.

Biologist Jesús Pineda studies how ocean currents and tides carry tiny larvae of coastal invertebrates such as barnacles from their places of origin to other sites where they can settle to the bottom and mature into adults. (Photo by Tom Kleindinst, WHOI)
