Barnacles have a relatively safe environment in which to live in, enough water for them to feed on while a whale swims, and a place to expand their colonies when whales are present. Vents serve as a proxy for extraterrestrial environments because they emit gases that are considered toxic to humans. Many anti-fouling compounds used to paint the undersides of boats are toxic, so Dr Dickinson's team hopes to find a more environmentally-friendly solution.
