Yaghra are fantastic, deep sea creatures that live in Nirn's many oceans and seas. The extent of the yaghra's spread across the world is generally unknown and they have no known names to surface-dwellers.

These crustacean creatures are protected by their chitinous carapaces, spikes, and strange internal biology. They are strongly influenced by pheromones and appear to communicate through their chemical physiology, sometimes regurgitating their stomach acids. The different forms of yaghra that have appeared throughout Tamriel may be unique breeds, or different morphologies of the same life cycle.

Yaghra Monstrosity

Yaghra monstrosities take on the role of the yaghra queens, rapidly reproducing larva. These enormous yaghra share a lot of similarities with the larva they produce. Their massive, enlarged abdomen is protected by a hard shell, and is cluttered with orifices that serve dual purposes. They can expel acidic bile in a pustulent eruption to defend themselves, or quickly produce new larva to create new soldiers.
