It is also found near the Mid-Atlantic Ridge south of Iceland. [14] P. arborea often grows on reefs created by the stony coral Lophelia pertusa. Like other gorgonians, it prefers exposed locations with strong currents. [15] Thus, is most commonly found in marine canyons and on the continental slope, where the slope is steep. [6]
Bird cliffs are found on islands in the North Atlantic and Arctic, such as the Faroe Islands, Iceland, the Svalbard archipelago and on islands off Northern Norway. Birds that nest in large numbers on bird cliffs include auks, kittiwakes, barnacle geese, and typical Old World vultures. The number of breeding couples may exhibit large variations ...
Eunicea is a genus of gorgonian-type octocorals in the family Plexauridae. These branched octocorals typically have knobby protuberances from which the polyps protrude. They are often stiffened by purple sclerites and some colonies, in brightly lit back-reef areas are purple, though most colonies are brown or grey. The polyps in some species ...
Eunicella verrucosa, the broad sea fan, pink sea fan or warty gorgonian, is a species of colonial Gorgonian "soft coral" in the family Gorgoniidae. It is native to the north-eastern Atlantic Ocean and the western Mediterranean Sea.
But starting in 2020, the birds began to nest around Ocean City and Cape May County, Boyle said. Earlier this month, birders counted a flock of about 100 white ibis in Atlantic County, he said.
Consequently, the term "gorgonian coral" is commonly handed to multiple species in the order Alcyonacea that produce a mineralized skeletal axis (or axial-like layer) composed of calcite and the proteinaceous material gorgonin only and corresponds to only one of several families within the formally accepted taxon Gorgoniidae (Scleractinia).
Deep cup nest of the great reed-warbler. A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too ...
Research has shown that measurements of the gorgonin and calcite within species of gorgonian corals can be useful in paleoclimatology and paleoceanography.Studies of the growth, composition, and structure of the skeleton of certain species of gorgonians, (e.g., Primnoa resedaeformis, and Plexaurella dichotoma) can be highly correlated with seasonal and climatic variation.
