DORSET'S WORLD HERITAGE COASTInside Out has descended beneath the waters of Dorset's world heritage coast. This voyage of discovery proves that you don't need to trek to exotic places to discover extraordinary creatures living secret lives. Seasearch project Marine conservationist Lisa Browning joined the Seasearch project for their dives. Seasearch is an ambitious national project to map the seabed off the British coast. We still know very little about life beneath the waves, so Seasearch is an exploration as well as adventure. Divers record everything they see, however small.

One of Seasearch’s interesting discoveries was a temporary city of spidercrabs off Lyme Bay. Once a year the spidercrabs gather together for safety while they molt their old shells and grow a new one. The Seasearch team collected unique footage of fifty thousand crabs gathered together for a few weeks. They then dispersed back to their solitary lifestyles off Dorset. SeahorsesSeahorses are under threat world-wide, but little is known about UK numbers. The Seasearch project may change this. These beautiful creatures not only mate for life, but it is the male which gets pregnant and gives birth. Wrasse | The Wrasse can change its sex

The Wrasse is another amazing creature that Seasearch has observed. It goes one step further and changes sex during its life. When the senior male wrasse dies, the most senior female in the area will change sex to replace him! These are just some of the remarkable discoveries about west Dorset sealife made possible by the Seasearch project. It opens up an underwater world that is sure to fascinate and intrigue as the project continues. |
