The Bull Netches are the males of the netches. Bull netches are greater in size and sometimes have a poisonous attack. They have a tannish shell while having a purple skin under the shell. Bull netches also have 5 tentacles compared to the females that have only four. They also are greater in numbers than the betty netch.
Netch skin is leathery in nature, and was often harvested to make armor, as well as a tower shield in the province of Morrowind. Netch leather is often said to sting the skin when it is worn, according to the book The Rear Guard.
