Pterogorgia guadalupensis is a blade-like gorgonian coral (family Gorgoniidae) found in shallow Caribbean reef environments, forming distinctive flattened, winged branches that give the genus its name. Its colonies display a characteristic yellow to orange coloration and are commonly found on exposed reef crests and upper slopes alongside other gorgonian species. Like other Caribbean gorgonians, it contributes to the structural complexity and biodiversity of coral reef communities. Genomic data have been generated for this species and are available in public databases, enabling comparative studies of cnidarian evolution and ecology.
