Isathi

The Isathi are a species of six-limbed humanoids with the natural ability to camouflage and thermal vision that originate on the planet Luvis. They are considered to be the natural predator for the Brathax, despite their comparatively weak bodies.

Biology
The Isathi are able to change the texture and color of their body, allowing them to camouflage themselves against any surface. Their vision is based off of thermal signatures, allowing them to track prey through the dense jungles of Luvis. This does make them somewhat blind, as they can't distinguish physical features, however they have developed a sort of echolocation that creates a mental image for them, using an incredibly quiet sound generated from deep within their bodies.

Their extra limbs developed similarly to the Brathax, though theirs were focused heavily on quick and efficient mobility, which they use to climb through the jungles of Luvis with impressive speed. The six limbs make them experts with firearms, and many find jobs as assassins across the Draco Perseus Galaxy.

Half of their head is dedicated to a large mouth filled with sharp, incredibly strong teeth designed for crushing and tearing through the tough skin of the Brathax. Their mouth is covered with four flaps that can open during feasting, and they can speak without opening the flaps.

The Isathi have little to no gender dimorphism. Females are almost identical to males, with the only distinguishing difference being internal reproductive organs.

Culture
The Isathi care little for colorful decoration, as all they see is thermal patterns. Their buildings are often considered barren and cheerless by other species, however the Isathi find most of their entertainment through each other, and sexual interaction is considered a normal event used for entertainment. Family isn't a feature within the Isathi society, with most children being left to fend for themselves after being born.

They treat other species fairly, except the Brathax, which they still view as animals to be hunted despite years of advancement. Due to this, both species have a deep seated hatred for each other.
