The word "barnacle" is attested in the early 13th century as Middle English "bernekke" or "bernake", close to Old French "bernaque" and medieval Latin bernacae or berneka, denoting the barnacle goose. [2][3] Because the full life cycles of both barnacles and geese were unknown at the time, (geese spend their breeding seasons in the Arctic) a folktale emerged that geese hatched from barnacles ...
Barnacles (balanus glandula) are sticky little crustaceans related to crabs, lobsters, and shrimps.
Barnacle defined and explained with descriptions. Barnacle is a small crustacean that attaches itself to marine objects such as rocks, and boats.
Barnacles are sessile marine crustaceans closely linked to crabs, lobsters, and shrimp. They are part of the subclass Cirripedia, which falls under the larger subphylum Crustacea. Encased in a cone-shaped shell composed of six calcite plates and a hinged lid made from four additional plates, barnacles are well-adapted to life in their chosen habitats.
Ever notice those little crusty clumps stuck to rocks, boat hulls or even whales? Those are barnacles, and while they might not look like much, they're marvels of the natural world. These tiny creatures are crustaceans, closely related to crabs and lobsters, and they’ve evolved some wild adaptations for life in the intertidal zone. Barnacles attach to a surface once and stay put for life.
barnacle, any of more than 1,000 predominantly marine crustaceans of the subclass Cirripedia highly modified for sedentary life. There are about 850 free-living species (all marine) and about 260 species that are internal parasites of crabs and other crustaceans. A brief treatment of cirripedes follows. For full treatment, see cirripede. As adults, typical barnacles are covered with calcareous ...
