Giant tube worms

Giant tube worm

Giant tube worms grow to over 2 metres long and inhabit the hot waters around hydrothermal vents on the Pacific Ocean bed. Like their cool water relatives, giant tube worms do not have a digestive tract. Their food is manufactured by bacteria that live symbiotically inside each worm's body. In return for their energy producing services, the bacteria are provided with a safe place to live and supplied with oxygen, carbon dioxide and hydrogen sulphide gathered by the worm's 'tentacles'.
