Marrus claudanielis, a new species of deep-sea physonect siphonophore (Siphonophora, Physonectae)
Marrus claudanielis, a new species of deep-sea physonect siphonophore, is described from material collected by the ROV TIBURON, off California (eastern North Pacific), and the submersible JOHNSON-SEA-LINK II, off New Jersey (western North Atlantic). Marrus claudanielis is extremely fragile and all o...
