Bergia puertoricense is a zoantharian anthozoan (family Sphenopidae, order Zoantharia) described from Puerto Rico and the Caribbean region, forming encrusting colonial polyp mats on hard substrates in tropical reef environments. The species belongs to the Brachycnemina, a major clade of zoantharians that includes species known for producing pharmacologically active secondary metabolites such as palytoxin. Its genomic resources contribute to understanding the evolution of zoanthid toxins and the systematics of Caribbean zoantharians.
