| Genus Dendronephthya
Kukenthal 1905: Strawberry Corals. Greatly bunched, bushy colonies.
Common in many areas of the tropical Indo-Pacific. Lack Zooxanthellae,
dependent of nano-plankton and dissolved organics for food. Some grow
exposed, many others in caves, sheltered settings, mostly "upside
down". Some 250 species are said to exist... not able to be
discerned in the field... must be microscopically examined. A "Spongodes"
specimen here in Bali 2014 |

| Genus Anthelia Lamarck 1816:
Clusters of polyps all arising from a united stolon base that is soft,
ribbon-like. Polyp pinnules in rows of 1-4 in number; slightly contractile,
not retractile; some don't even respond to touch. Unlike Heteroxenia and
Xenia species, Anthelia colonies branch at their base of attachment. Bali

Genus Xenia Lamarck 1816: Small cylindrical colonies (up to 4
cm in all dimensions typically), dome shaped. Sometimes branched, with
polyps only at apical stems. One-shape polyps with varying capacity to
retract, 1-6 pinnules on both sides (number of rows, pinnules
species-specific). Some pulsate, some don't. Forty plus
species, scattered over the Indo-Pacific. Fed on by similar appearing
Nudibranchs of the genus Phyllodesmium. Bali 2014 |
