For those triggers that cannot be avoided, you can try to compensate with extra care in other ways. For example, when your child has a cold, you can try to ensure he gets lots of sleep and nutritious foods. Some triggers may become more of an issue as your child gets older.
barnacle. n. 1. (Animals) any of various marine crustaceans of the subclass Cirripedia that, as adults, live attached to rocks, ship bottoms, etc. They have feathery food-catching cirri protruding from a hard shell. See acorn barnacle, goose barnacle.
Barnacles, somewhat surprisingly, are crustaceans (like crabs, lobsters, krill, etc.). Unlike most crustaceans, however, adult barnacles are sessile â they canât move. After a short phase spent as planktonic larvae, barnacles settle, attach to a hard substrate, and never move again. The Acorn Barnacle is one species in a large group of species with the same common name that do not have stalks and instead attach their shells directly to the substrate. Gooseneck Barnacles are a common example of the stalked variety.
