26 May 2014
Join us on a simulated journey through the undersea landscapes of the south west of England from Ilfracombe to delicate pink sea fans in Lyme Bay via Chesil Beach and Berry Head. Common cuttlefish, hermit crab, bootlace seaweed and long snouted sea horse can be found here. Watch plaice send a hermit crab packing before approaching The Lizard’s thick carpets of jewel anenomes, dead man’s fingers and Devonshire cup coral. As we reach the Atlantic we come across sun fish, lion’s mane jellyfish, basking sharks and bottle-nosed dolphins before surfacing at Ilfracombe in Devon. Grey seals swim along corkwing wrasse, ballan wrasse and swimming crabs all searching for food amongst sponges.
Translated from Ecomare museum on Texel island in the Netherlands, 16 September 2014:
During a 10-day diving expedition in the North Sea there were a number of discoveries in ancient sunken ships. The rare polychaete worm Sabellaria [spinulosa] was found for example. But the most remarkable find was a piece of Devonshire cup-coral. Although this species lives occasionally near the English east coast, it was the first time that hard coral was found in the middle of the North Sea.
