By Bob Fenner


Genus Parerythropodium

Parerythropodium fulvum (Forsskal 1775), Sulfur Coral, Yellow Encrusting Leather Coral. Below: a colony and close-up in the Andaman Sea off of Thailand in the Similans that is about six inches across, and a typical creeping colony in the Red Sea. 

Genus Rhytisma Alderslade 2000: Thin encrusting mats that are often ribbon-like, of 2/4 mm depth. Have large gastric cavities that appear to burst right out of the basal mat membrane. Reproduction is mainly asexual, through fragmentation.

Rhytisma sp. Red Sea, open and closed colonies.

Genus Sarcophyton: Mushroom, Leather, Cup Leather Coral

Shedding... An important aspect of Sarcophyton captive husbandry is their periodic sloughing of skin/mucus, sand et al... this is one shedding in the wild off of Queensland, Australia. Do vacuum, remove this material. 

Sarcophyton crassocaule Cebu, Philippines and Fiji.

Sarcophyton ehrenbergii Marenzeller 1885. Common in the Indo-Pacific and aquariums. Laterally compressed colonies with deep disks. Feeds by way of photosynthesis and plankton.

Sarcophyton glaucum (Quoy & Gaimard 1833),  Red Sea, Indo-Pacific. Hardy, easily reproduced asexually. To one foot in diameter. Feeds on plankton or similar material. A small and tiny one fully open in Pulau Redang, Malaysia.

Sarcophyton sp. (elegans?) 

These young colonies on the reef flat in Fiji and an aquarium.

Sarcophyton tenuispiculatum Thomson & Dean 1931. The Gold-Crowned Leather Coral. Common in its range in the Indo-Pacific. A tough aquarium species that needs lots of space, high intensity light and strong water movement. Aquarium photo.

Sarcophyton trocheliophorum Marenzeller 1886, Elephant Ear Soft Coral. A large alcyoniid with symbiotic zooxanthellae. This and fine plankton, dissolved organics are nutritive. To two feet across. A popular aquarium species that loses easily to stinging anemones, large polyp stony corals. Likes bright light, moderate current. Red Sea at right, close-up and below left, Cebu (Philippines) and Maldives images.

Sinularia polydactyla. Here are images showing a group of colonies at the reef lip and one open at night feeding in the Red Sea.
