Ecology and Gametogenic Biology of the Genus Umbellula (Pennatulacea) in the North Atlantic Ocean
Abstract Four putative species of the seapen genus Umbellula, U. lindahli, U. thomsonii, U. durissima and U. monocephalus , are found at bathyal and abyssal depths in the Porcupine Seabight and Abyssal Plain in the NE Atlantic Ocean and at bathyal depths off the Bahamas. The most common species, U....
