Aquanorn

From Creatures Wiki

The Aquanorns were drawn by Tomtschek with a genome by Alien. They are amphibious, and breathe a lot better underwater then they do on land. They go from having legs and a developing fish tail, to only having the fish tail. Once this fin has grown, they can swim. Given this similarity, it's possible they have at least a spiritual relation to MerNorns.

The home of these norns is the Aqua Garden, also made by Tomtschek. They can be downloaded at the Norngarden site. They use Ettin slot K.
