Lochranza Castle is situated on a peninsula extending into beautiful Loch Ranza in the north of Arran.

Barnacles are of economic consequence, as they often attach themselves to synthetic structures, sometimes to the structure's detriment. Particularly in the case of ships, they are classified as fouling organisms. [44] The number and size of barnacles that cover ships can impair their efficiency by causing hydrodynamic drag. This is not a problem for boats on inland waterways, as barnacles are exclusively marine. Bromham, Lindell (2020-10-01). "Comparability in evolutionary biology: The case of Darwin's barnacles".

The word "barnacle" is attested in the early 13th century as "bernekke" and originally referred to a species of goose. Because the full life cycles of both barnacles and geese was unknown at the time, (geese spend their breeding seasons in the Arctic) a folktale emerged that geese hatched from barnacles. It was not applied strictly to the invertebrate until the 1580s. The ultimate meaning of the word "barnacle" is unknown. [11] [12] Life cycle [ edit ] A ring of plates surrounds the body, homologous with the carapace of other crustaceans. These consist of the rostrum, two lateral plates, two carinolaterals, and a carina. [6] In sessile barnacles, the apex of the ring of plates is covered by an operculum, which may be recessed into the carapace. The plates are held together by various means, depending on species, in some cases being solidly fused. [ citation needed] Inside body [ edit ] a b c d e f g h i j k P. Doyle; A. E. Mather; M. R.

Blistering Barnacles! The bane of many a seafarer, the humble barnacle is responsible for a multi-billion dollar biofoul industry. Here are some unusual facts about this tenacious crustacean. Barnacles can play an important role in estimating paleo-water depths. The degree of disarticulation of fossils suggests the distance they have been transported, and since many species have narrow ranges of water depths, it can be assumed that the animals lived in shallow water and broke up as they were washed down-slope. The completeness of fossils, and nature of damage, can thus be used to constrain the tectonic history of regions. [3]Like many English words and phrases, the description of something reliable as “copper-bottomed” has a maritime origin.
