Dragmacidon reticulatum

Dragmacidon reticulatum is a sponge species belonging to the family Axinellidae. It is typically found in tropical regions of the Western Atlantic and Pacific Ocean, particularly in the Caribbean. This species is associated with reefs and can inhabit various environments such as rock patches, mangrove roots, and coral reefs. It thrives at depths ranging from 0.5 to 70 meters, although most observations occur at shallower depths, with 92% of records being less than 40 meters deep. The sponge is characterized by its massive-amorphous, lobate, or mound-like shape, and is notable for its bright red color both externally and internally. It has small conules that vary in height from 0.05 to 0.2 cm and abundant oscules with diameters between 0.3 and 0.6 cm. When cut, the sponge exhibits a slimy texture. As a member of the class Demospongiae, Dragmacidon reticulatum is hermaphroditic, with a life cycle that includes a free-swimming parenchymella larva stage before settling on a substrate to mature into a sponge. Divers encountering Dragmacidon reticulatum may notice its bright red coloration, which can stand out against the backdrop of the reef. Its harmless nature makes it an interesting subject for underwater observation. However, its conservation status has not been evaluated by the IUCN, and there are no known threats to humans.
