Red sea fingers is similar in shape to Alcyonium digitatum but is usually blood red or rust coloured. The finger-shaped lobes are slender and can be up to thirty centimetres long. The polyps are white and each one has eight pinnate tentacles which give the colony a feathery appearance when they are extended. [2]
Gorgonians possessing zooxanthellae are usually characterized by brownish polyps. Gorgonians are found primarily in shallow waters, though some have been found at depths of several thousand feet. [4] [6] The size, shape, and appearance of gorgonians can be correlated with their location. The more fan-shaped and flexible gorgonians tend to ...
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.
The seals can live for as many as 35 years in the wild while dealing with predators like orcas and larger leopard seals. They survive on fish, squid, and other smaller prey to survive.
The two main subclasses of Anthozoa are the Hexacorallia, members of which have six-fold symmetry and includes the stony corals, sea anemones, tube anemones and zoanthids; and the Octocorallia, which have eight-fold symmetry and includes the soft corals and gorgonians (sea pens, sea fans and sea whips), and sea pansies.
Briareum asbestinum, commonly known as the corky sea finger, is a species of a soft coral in the family Briareidae. [1] It inhabits coral reefs and rocky bottoms in the Caribbean, Bahamas, and Florida, often growing to 30 cm at depths of one to 40 metres.
Hippocampus bargibanti, also known as Bargibant's seahorse or the pygmy seahorse, is a seahorse of the family Syngnathidae found in the central Indo-Pacific area. [3]This pygmy seahorse is tiny—usually less than 2 centimetres (0.79 in) in size—and lives exclusively on gorgonian sea-fans, as its coloration and physical features expertly mimic the coral for camouflage.

Nemanthus annamensis, commonly known as the gorgonian wrapper, is a species of sea anemone found in central Indo-Pacific waters. [1] Description
