Slan

The Slan are a subterranean, eusocial species native to Thadek'ha. They perceive and understand their world entirely through the perception of sound. They have developed into a spacefaring society, and are one of the many client species of the Sh'daar.

Anatomy
Slan are round, flattened creatures, shaped roughly like a hemisphere. They are roughly two meters tall and three meters wide. The body is ringed by around 60 tentacles, three of which are much longer than the rest and act as arms. Two prehensile stalks emerge from the top of the body, tipped with conical, fatty echolocation organs. A small photoreceptive organ, not quite an eye, sits directly on top of the body. Slan are typically a mottled brown in color.

Diet
Slan are stated to be carnivores, but their feeding methods are never described.

Reproduction
Only certain members of the species, likely a specific caste, are allowed to reproduce. Non-reproductive Slan do not appear to have a sex or gender and identify as "it."
