ROVs are also used extensively by the scientific community to study the ocean. A number of deep sea animals and plants have been discovered or studied in their natural environment through the use of ROVs; examples include the jellyfish "Stellamedusa ventana" and the eel-like halosaurs. In the US, cutting edge work is done at several public and private oceanographic institutions, including the Monterey Bay Aquarium Research Institute (MBARI), the Woods Hole Oceanographic Institution (WHOI) (with "Nereus"), and the University of Rhode Island / Institute for Exploration (URI/IFE).
