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 classification of corals has been discussed for millennia, owing to having similarities to both plants and animals. Aristotle's pupil Theophrastus described the red coral, korallion, in his book on stones, implying it was a mineral, but he described it as a deep-sea plant in his Enquiries on Plants, where he also mentions large stony plants that reveal bright flowers when under water in ...
Primnoa (Lamororux, 1812) also known as red tree coral, is a genus of soft corals and the type genus of the family Primnoidae (Milne Edwards, 1857). [1] They are sessile, benthic cnidarians that can be found in the North Pacific, North Atlantic, and Subantarctic South Pacific, [2] and its members often play a vital ecological role as keystone species [3] within their environment as a habitat ...
The conspicuous, even dramatic coral trees are widely used as floral emblems. cockspur coral tree (E. crista-galli) is the national flower of Argentina and Uruguay. The coastal coral tree ( E. afra ) is the official city tree of Los Angeles , California , where it is referred to simply as the "coral tree". [ 13 ]
Coral reefs are some of the most biodiverse habitats on earth, supporting large numbers of species of corals, fish, molluscs, worms, arthropods, starfish, sea urchins, other invertebrates and algae. Because of the photosynthetic requirements of the corals, they are found in shallow waters, and many of these fringe land masses. [24]
Corals are vital for the marine creatures that rely on them for food and shelter, but also for humans. They are an indirect food source for an estimated 1 billion people, by helping support ...
Corals divert energy and resources towards repairing damage, which has shown to suppress additional growth. [2] [11] [5] [6] The ability for a coral to repair itself is partially based on the size of the lesion; since not all damage can be healed, superfluous damage can result in permanent change to the reef.

Fungia corals, like other large polyp stony corals, have developed several feeding strategies. They also capture planktonic organisms, food particles from the water column, and can absorb dissolved organic matter. Feeding tentacles are usually visible at night. Fungia also reproduce asexually.
