An internal wave is a gravity wave that moves along density stratification within the ocean. When a water parcel encounters a different density it oscillates and creates internal waves. [ 113 ] While internal waves generally have a lower frequency than surface waves, they often form as a single wave that breaks into multiple waves as it hits a ...
Primnoa pacifica or red tree coral is a species of soft coral in the family Primnoidae. It is a deep water coral found in the North Pacific Ocean, and plays an integral role in supporting benthic ecosystems. Red tree corals grow axially and radially, producing structures of calcite and gorgonian skeletons that form dense thickets.
The ocean’s waves generate enough force to move the corals — sometimes in the wrong direction — but gravity and the slope of the reef tend to move the creatures back down.
Anthozoans are exclusively marine, and include sea anemones, stony corals, soft corals, sea pens, sea fans and sea pansies. Anthozoa is the largest taxon of cnidarians; over six thousand solitary and colonial species have been described. They range in size from small individuals less than half a centimetre across to large colonies a metre or ...
Scientists call it an ‘inverse thermocline.’
Many soft corals are easily collected in the wild for the reef aquarium hobby, as small cuttings are less prone to infection or damage during shipping than stony corals. Nevertheless, home-grown specimens tend to be more adaptable to aquarium life and help conserve wild reefs.
As observed in other species of corals, space for settlement on the reef is one of the most important limiting factors for new colonies of L. arboreum. [5] Similarly, physical factors—such as wave action, temperature variation, salinity and light– and biological factors– such as competition, predation, and disease– limit the success and ...
The "mega" coral is 112-feet wide, 105-feet long and 18-feet high, making it larger than a blue whale, the world's largest animal.
