It has a large fin lining its back and barnacles covering certain parts of its body, similar to real-life baleen whales.

The Serpent's Heir

When the Dragon Riders were about to reach Nepenthe, Hiccup used his spyglass to observe a Fathomfin surfacing in the distance before commenting on its brief yet mysterious presence. Fishlegs immediately got excited about it and wanted to know more about the new dragon, but Hiccup told him that investigating the situation on Nepenthe was at the moment more important than studying the Fathomfin.
