Two new species of submarine shrimp-like creature, capable of ‘stripping’ a pig carcass in a matter of days, have been discovered by a team of scientists. These 3mm long scavenging crustaceans, known as amphipods, live in depths of up to 4500 metres in the North Atlantic Ocean. They act in swarms to strip the carcasses of dead marine animals, including whales, fish and seabirds.
