Lyme Bay extends for 65 kilometres from Exmouth in East Devon to Portland in West Dorset. In Lyme Bay the cold water from the North meets the warmer water from the South. This results in cold and warm water species living in Lyme Bay. The reef habitat of Lyme Bay is home to a rich diversity of marine life. There are over 300 hundred plants and animals including rare and protected species and seven species of coral. The reefs in Lyme Bay also host valuable seafood species such as crab and scallop.
