Diplosoma aff. spongiforme
Taxonomic Group: Tunicates


Diplosoma aff. spongiforme is native to the Northeast Atlantic, ranging from Scotland south to the Atlantic coast of Spain and the Mediterranean Sea. In 2002, a colonial tunicate closely resembling D. aff. spongiforme was found on Smithsonian fouling plates in Tampa Bay and Miami Harbor, Florida. In 2007, the same tunicate was found on fouling plates in Puerto Rico and a similar spongiforme-like tunicate was reported from the Currais Islands, Brazil. There are no reported impacts of introduced populations of D. aff. spongiforme.
