Protopalythoa psammophia

Bright Green Buttons

Range: Indo-West Pacific Ocean

Natural Environment: Inhabits shallow, sandy reef flats and hard bottom areas.

General Husbandry: Occasionally seen in the trade.

Polyps are usually bright green, sometimes a fluorescent green!

Even though it contains zooxanthellae, supplemental feedings of baby brine shrimp will help the polyps multiply.

Taxonomy:

Kingdom: Animalia

Phylum: Cnidaria

Class: Anthozoa

Subclass: Hexacorallia

Order: Zoantharia

Suborder: Brachycnemina

Family: Zoanthidae

Genus: Protopalythoa

FYI: As with all Palythoa/Protopalythoa species, they produce a toxin called palytoxin (Mebs, 1989) that is found in its mucus coating. It is used to protect itself from predators and also clear the path of other corals so as to make space for expanding its colony. Keep in mind that if this toxic mucus enters your eye, mouth, or an open wound, it can cause various disorders including numbness, hallucinations, or even death. Therefore, always wash your hands after handling these creatures, and never handle them if you have open wounds on your hands! Wearing gloves is a good idea when handling these animals!
