New species are even being found at depths of 2,500m (8,200ft). Everywhere! While they are most diverse in shallow, warm waters, there are two main types of nudibranch: Dorids and Aeolid. They have distinct defining features, which I shall get into later. (I feel you need a little more information first!) Most...
