Pocillopora inflata is a species of stony coral in the family Pocilloporidae. It was first described by Peter William Glynn in 1999. It is found growing on coral reefs in the tropical eastern Pacific Ocean but is nowhere abundant.

Description

Pocillopora inflata is a colonial, zooxanthellate, arborescent coral. It varies in shape, sometimes forming knobbly mounds which can grow to 1 metre (3 ft 3 in) across, and sometimes having a more open structure with short branches several centimetres in diameter. The colour ranges from yellowish brown to shades of green. [3] It can be distinguished from other members of the genus by the fact that it has swollen ends to the branches, a small number of pointed verrucae (or none at all) and prominent columellae on the lower part of the colony. [4] The corallites are small and densely crowded and some of the septa, which are indistinct, are fused with the columella. The polyps have 12 tentacles. [5]

Distribution and habitat

Pocillopora inflata occurs in the tropical eastern Pacific Ocean from the coast of Mexico to Ecuador and the Galápagos Islands. It favours rocky shores and grows at depths of less than 10 metres (33 ft). [1]

Ecology

This species often grows among other Pocilloporid corals. Corals in the genus have relatively fast growth rates, with Pocillopora inflata growing at the rate of 2 to 4.4 centimetres (0.79 to 1.73 inches) a year. Most Pocilloporids brood their planula larvae, and this may also be true of Pocillopora inflata, but it has on one occasion been observed to broadcast eggs and sperm into the sea in a synchronised spawning event. [1]

It has a number of predators. These include pufferfishes, parrotfishes and filefishes which feed on the branch tips and hermit crabs which scrape the skeletal tissue. Other predators feed on the soft tissues while leaving the skeleton intact. These include such fish as the butterflyfishes, the angelfishes and the damselfish, Stegastes acapulcoensis . Invertebrate predators include the crown-of-thorns starfish, the sea urchin, Eucidaris galapagensis , and the gastropods, Jenneria pustulata and Quoyula sp. [1]

Pocillopora inflata has several mutualistic symbionts including the crab, Trapezia sp., and certain snapping shrimps which protect it from attack by its major predator, the crown-of-thorns starfish. [1]

Threats

Pocillopora inflata is an uncommon coral throughout its range and is more susceptible than many other species to bleaching and to predation by the crown-of-thorns starfish which is becoming more abundant in some areas. [1] In common with other corals, it is threatened by rising sea temperatures, ocean acidification, ENSO events, severe storms, coral diseases, pollution and coral harvesting. [1]

<span class="mw-page-title-main">Anthozoa</span> Class of cnidarians without a medusa stage

Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals and soft corals. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton. The basic unit of the adult is the polyp; this consists of a cylindrical column topped by a disc with a central mouth surrounded by tentacles. Sea anemones are mostly solitary, but the majority of corals are colonial, being formed by the budding of new polyps from an original, founding individual. Colonies are strengthened by calcium carbonate and other materials and take various massive, plate-like, bushy or leafy forms.

<span class="mw-page-title-main">Crown-of-thorns starfish</span> Species of starfish

The crown-of-thorns starfish, Acanthaster planci, is a large starfish that preys upon hard, or stony, coral polyps (Scleractinia). The crown-of-thorns starfish receives its name from venomous thorn-like spines that cover its upper surface, resembling the biblical crown of thorns. It is one of the largest starfish in the world.

<span class="mw-page-title-main">Scleractinia</span> Order of Hexacorallia which produce a massive stony skeleton

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. Although some species are solitary, most are colonial. The founding polyp settles and starts to secrete calcium carbonate to protect its soft body. Solitary corals can be as much as 25 cm (10 in) across but in colonial species the polyps are usually only a few millimetres in diameter. These polyps reproduce asexually by budding, but remain attached to each other, forming a multi-polyp colony of clones with a common skeleton, which may be up to several metres in diameter or height according to species.

<i>Hymenocera</i> Genus of crustaceans

Hymenocera picta, commonly known as the harlequin shrimp, is a species of saltwater shrimp found at coral reefs in the tropical Indian and Pacific Oceans. It is usually considered the only species in the genus Hymenocera, but some split it into two species: H. picta from the central and east Pacific, where the spots are deep pinkish-purple with a yellow edge, and H. elegans from the Indian Ocean and west Pacific, where the spots are more brownish and have a blue edge. They reach about 5 cm (2.0 in) in length, live in pairs, and feed exclusively on starfish, including crown-of-thorns starfish. They do seem to prefer smaller, more sedentary starfish, but as these generally are not sufficiently numerous for their needs, they commonly attack crown-of-thorns starfish, both reducing its consumption of coral while under attack, and killing it within a few days.

A corallivore is an animal that feeds on coral. Corallivores are an important group of reef organism because they can influence coral abundance, distribution, and community structure. Corallivores feed on coral using a variety of unique adaptations and strategies. Known corallivores include certain mollusks, annelids, fish, crustaceans, flatworms and echinoderms. The first recorded evidence of corallivory was presented by Charles Darwin in 1842 during his voyage on HMS Beagle in which he found coral in the stomach of two Scarus parrotfish.
