A. arborensis

Just dropping in to remind people that I do spend time drawing! I've been working more on learning how to color things digitally, and I'm pretty happy with how this turned out. I've been toying around with my rattler's design a bit to make them look more plausible/aesthetically pleasing... went with a more lithe and agile look this time around, since they are supposed to be proficient climbers. If I were to do it again, I'd change their middle arms to be a bit longer (and, since I'm being nitpicky, the ribs on its tongue are supposed to run the other way). 
Any feedback/critique is greatly appreciated! 

Here we have an adult Anomalosapiens arborensis (lit. strange thinker from the trees), more commonly known as "rattlers" by humans thanks to their odd vocalizations and semi-reptilian appearance. They are the sole sentient inhabitants of the verdant moon Vishnu, and the once proud owners of a highly advanced global society. 

Rattlers, along with other Vishnuvian megafauna, belong to the phylum Simulaphora. Simulaphores (as well as organisms in neighboring phyla) are in technicality colonial colonies, with bodies made of incredibly disparate clones coming together to form a single functional genet. Each clone is distinguished by having a single pair of legs and similar organ structures, with the head segment possessing a hypertrophied neural bulb as well as the reproductive organs for the entire genet. 

In rattlers these reproductive organs are housed in a colorful protective sheath on the chest, lined with bristles highly sensitive to touch and, to a lesser extent, taste. The sheath holds a grooved tongue-like organ used for the transmission of gametes between partners. Unlike many terran animals, Vishnuvian fauna tend to lack gender. They instead possess (+) or (-) capable egg-like gametes, which are only able to fertilize "eggs" of the opposite type. Subtle pheromone queues allow rattlers to determine the current mating type of a potential partner, though phenotype changes are used to indicate mating type in other Vishnuvian animals. Rattlers, like many other pheromone indicating species, are capable of swapping mating type during their lifetime. Since both (+) and (-) gametes fertilize one another, both partners may become pregnant.
