Coral Knowledge Week 4 by Emily

After reviewing some of the most common families in the past 3 weeks I have decided to review a couple of more unusual families. Oculinidae, Euphyllidae and Dendrophylliidae only have 1 genre for each.


The Oculinidae family consists of Galaxea.


The Euphyllidae family consists of Physogyra


The Dendrophylliidae family consists of Turbinaria


Galaxea Oculinidae is generally seen in encrusting, submassive and massive forms. It has very distinctive tubular corallites which rise at least 2mm. If wafted they do not react like some other coral genres with a similar appearance of tubular corallites.

Galaxea is found in a wide variety of bright and vibrant colours, including blue, purple, green and yellow.


Physogyra Euphyllidae is most commonly found in massive or encrusting form. It has the appearance of hundreds of tiny balloons. These are swollen bubble shaped vesicles. It is very difficult to see the skeleton of the coral due to the fact that it is mostly constructed of thin blade like plates. The vesicles will retract if felt under enough pressure.


Turbinaria Dendrophylliidae is most commonly seen in foliose form but can occasionally be seen in submassive and encrusting forms. The coenosteum (the skeletal matrix around the corallites) appears to be very smooth with the corallites being very well spaced and on top of ‘tubey lumps’


Next week I shall be doing a pod cast on the different and quirky ways of remembering certain corals!!
