Dashta eel
From Wookieepedia, the Star Wars wiki.
The Dashta eels were a species of animal native to Ord Cestus and unknown to the outside galaxy. Immature ones were the size of a clenched Human fist when coiled, and had blind eyes. The young had no sex; after they matured, they entered into sexual differentiation, gained a form of sentience, and grew larger. Unfertilized eggs develop into dashta eels that remain immature and non-sentient. The head eels were the Guides.
Dashta eels were from the Zantay Caves, and were worshiped by the X'Ting for thousands of years. They were named after Kilaphor Dashta.
The unfertilized dashta eels were given to the X'Ting so that they could make JK-series droids. Although they weren't sentient, they still demonstrated a profound level of Force sensitivity. They were the first known example of non-sentient Force sensitives. The adult Dashta eels also gave the X'Ting the first fungal spores used for food and medicne long ago.
