Latest Barnacle Stories
A common problem at Pearl Harbor, biofouling affects harbors around the world. It's the process by which barnacles, muscles, oysters, and tubeworms accumulate on the bottom of boats and other surfaces.
Two new species of the gorgonian inhabiting barnacles — Conopea saotomensis and Conopea fidelis — have been collected from the area surrounding the historically isolated volcanic islands of São Tomé and Príncipe.
The colonization of hulls by algae, barnacles, mussels and other organisms is a major problem for both pleasure boats and merchant tonnage.
Chemists discover how oysters bond together to form massive reef complexes.
The substance medetomidine has proved effective in preventing fouling of ship bottoms, and now, researchers have identified the gene that causes the barnacle to react to the substance.
The barnacle, a key thread in the marine food web, was thought to be missing along rocky coasts dominated by upwelling.
Researchers have solved the mystery of how barnacles attach themselves to other objects, showing that barnacle glue binds together exactly the same way as human blood does when it clots.
North Carolina State University engineers have created a non-toxic "wrinkled" coating for use on ship hulls that resisted buildup of troublesome barnacles during 18 months of seawater tests, a finding that could ultimately save boat owners millions of dollars in cleaning and fuel costs.
A study published in BioMed Centralâ€™s open access journal, BMC Biology, reports the transformation of the larvae into a previously unseen, wholly un-crustacean-like, parasitic form.
Covering ship hulls with artificial shark skin could help ships sailing smoothly. The growth of marine organisms such as barnacles on ship hulls is a major cause of increased energy costs in the naval industry. Shark skin offers a structural design that prevents this so called 'bio-fouling'.
The ochre sea star (Pisaster ochraceus), also known as the ochre starfish or the purple sea star, is a species of starfish that is classified within the Asteriidae family. This species can be found in the Pacific Ocean in a range that extends from Santa Barbara Co., California to Prince William Sound in Alaska. This species holds one subspecies, known as Pisaster ochraceus segnis, which can be found in warmer waters that the ochre sea star. Adult individuals prefer a habit in rocky areas at...
The giant sea star (Pisaster giganteus) is a species of starfish that is classified within the Asteriidae family. It can be found along the western coasts of North America, with a range that extends from British Columbia to southern California. It resides in areas with low tides, where sand contains abundant substrate to which the starfish can cling. The giant sea star is broad and holds wide arms, reaching between 14.1 and 18.8 inches from arm to arm. Like other starfish species, this sea...
The pink sea star (Pisaster brevispinus), also known as the short-spined sea star or the giant pink sea star, is a species of starfish that is classified within the Asteriidae family that can be found in the Pacific Ocean. It prefers to reside in muddy or sandy areas at depths of up to 590 feet, although smaller individuals can be found in rocky areas. This species was made famous by the show Spongebob Squarepants, where the main character’s best friend is a pink sea star. The pink sea...
The Barnacle Goose (Branta leucopsis) belongs to the genus of black geese named Branta. This genus contains species with mostly black plumage, distinguishing them from the grey Anser species. Despite its superficial outward similarity to the Brent Goose, genetic analysis has shown it is an eastern derivative of the Cackling Goose lineage. It is easily identified by its largely black plumage and white face. Its call is a "kaw". During breeding season, Barnacle Geese can be found mainly on...
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
