UC Berkeley researcher Larry Taylor knew that present-day barnacle shells take up differently weighted oxygen atoms from bodies of water. That creates a record of the oceans they’ve been in as ...
Once barnacle larvae mature, they travel on ocean currents in search of an anchoring place, preferentially settling in locations with good water flow, which often happen to be moving marine animals.
Gooseneck barnacle populations are declining at a rapid pace. The effects of these decreasing numbers are being felt in Spain, where the barnacles are a delicacy, especially at Christmastime.
