Overview

Comprehensive Description

"Pavona forms foliaceous, encrusting or massive colonies. Foliaceous types have fronds that are entire and flat or twisted and fused together. In general, calices are on both sides of the vertically growing fronds or plates but on the upper face only of horizontal folia. Most colonies are pale brown. Some show shades of gray, pink, purple, green or yellow, and often the tops of the collines are paler or white. In some cases the calices are a different color from the rest of the coral. Tiny tentacles less than a millimeter in length are sometimes extended during the day. Calices are round, polygonal or oval. In many species hillocks called collines are present between the calices. These are usually acute and may be elongate. Some enclose a single calice, but most surround a short series, giving a complicated system of ridges and grooves. In Pavona clavus there are low walls between the calices. These are usually separated, each with its own wall. Calice diameter is usually between 2 and 3 mm. Septa are visible as fine lines running from one calice center to the next, continuing uninterrupted over walls and collines. Often they form characteristic star-shapes patterns over the surface of the corallum. They are extremely fine, and the coral is smooth to the touch. Pavona is a fairly common coral that is found in most reef habitats. Some of the massive colonies are large, and the foliaceous ones may form extensive tracts." (Dr. Elizabeth M. Wood, 1984).

Physical Description

Diagnostic Description

Description

Colonies are massive, laminar or foliaceous, the latter usually being bifacial. Corallites have poorly defined walls. They are small shallow depressions, usually with a central columella, sometimes separated by ridges. Corallites are interconnected by prominent septo-costae. Except for P. explanulata, polyps are extended only at night (Veron (1986)). Colonies may be foliaceous or globular and often dominate coral communities. Typically with prominent septo-costae connecting adjacent corallites. Polyps usually extended at night (Richmond, 1997).

Pavona (genus)

Pavona is a genus of colonial stony corals in the family Agariciidae. These corals are found in shallow waters in the Indo-Pacific region.

Characteristics[edit]

Corals in this genus have a range of different forms including those that are massive, meandering, columnar, leaf-like, and plate-like. A single species may vary in form according to the current, wave action, lighting conditions, and depth of its location. Members of the genus are distinguished from other corals by having no walls to the corallites, but having clearly delineated septocostae that connect each corallite to its neighbours, giving a flower-like pattern on the surface of the coral. The corallites themselves are shallow depressions with central columella and may be separated by ridges. The polyps, with the exception of Pavona explanulata, are only extended at night. The foliose and plate-like forms tend to be two-sided.[1][2]
