Deep water coral habitats are also threatened by human activities, particularly by indiscriminate trawling. These ecosystems have been little studied, but in the perpetual darkness and cold temperatures, animals grow and mature slowly and there are relatively fewer fish worth catching than in the sunlit waters above.
The coral is densely branched but usually grows in a single plane. The colour varies and is usually some shade of red, orange or deep yellow but purple specimens occasionally occur. The skeleton is not rigid so the whole fan-like structure can sway with the movement of the surrounding water.
The branch coral (Acropora florida) is a species of acroporid coral found in the southwest and northern Indian Ocean, the central Indo-Pacific, Australia, Southeast Asia, Japan and the East China Sea, Cook Islands and the oceanic west Pacific Ocean. It can be found in shallow reefs on the reef tops, walls and slopes to depths of 30 m.
Acroporidae is a family of small polyped stony corals in the phylum Cnidaria.The name is derived from the Greek "akron" meaning "summit" and refers to the presence of a corallite at the tip of each branch of coral. [3]
A Petoskey stone is a rock and a fossil, often pebble-shaped, that is composed of a fossilized rugose coral, Hexagonaria percarinata. [1] Such stones were formed as a result of glaciation, in which sheets of ice plucked stones from the bedrock, grinding off their rough edges and depositing them in the northwestern (and some in the northeastern) portion of Michigan's lower peninsula.
G. ventalina is a fan-shaped colonial coral with several main branches and a latticework of linking smaller branches. The skeleton is composed of calcite and gorgonin, a collagen-like compound. The calyces in which the polyps are embedded are in two rows along the branches.
Several species of coral-inhabiting barnacles are associated with Astreopora. In fact, Hiroa stubbingsi and two species of Cionophorus seem to occur nowhere else. In the case of H. stubbingsi , which has a primitive wall and a relatively unspecialised operculum , this may be because it is not equipped to occupy other corals, but the Cionophorus ...
Scleractinia, also called stony corals or hard corals, are marine animals in the phylum Cnidaria that build themselves a hard skeleton.The individual animals are known as polyps and have a cylindrical body crowned by an oral disc in which a mouth is fringed with tentacles.
