Bildir
Bildir evolved in coastal deltas and swamps, and eat plankton, algae, and soft bodies prey. They naturally feed by dipping their head upsidedown in the water like a flamingo, breathing through the nostrils at their clavicle, or by slurping up stringy algaeic mats. A common form of processed food is strings of dessicated algae braided into ropes that can be boiled back to edibility.
Bildir agriculture primarily consist of creating terraced dams to collect and stagnate water until it is gelatinous with algae and invertebrates. This material is either eaten fresh, or dessicated to be dehydrated later.
An early public misconception about Bildir is the idea that they are primarily bipedal. Though they can move bipedally in order to carry objects or to make use of their height (Typically 8-10' fully upright) for sight or intimidation, they are primarily quadrupedal. This idea arose from most early images seen by foreigners showing them standing upright, but this is merely because that erect posture is used to convey formality and presence intentionally, or fear and discomfort reflexively (Bildir can distinguish these seemingly opposite meanings for the same posture, but most non-Bildir cannot). Bildir move most comfortably and efficiently on all fours, and can move equally quickly and gracefully in any direction when doing so.
Bildir have long, double-elbowed limbs with a membrane between the first and third span that enables them to swim efficiently with a slow rowing motion, reach between rocks and logs when climbing or striding, and deliver powerful blows when necessary.
Each limb ends with a hand composed of seven slender digits each tipped with a pair of durable hooked claws, and joined by a tough gritty-textured membrane. These surround a sturdy knob that serves a similar role to a hominid heel, and sometimes functions as a thumb for handling heftier tools.
Many Bildir are able to cup air in their hands and float above the surface of calm, sufficiently algaeic or salty water, though usually only juvenile individuals can do this on clear freshwater.
Despite Bildir mouthparts looking quite intimidating to other species, they are too fragile to be used in combat and their exposure usually is simply part of stretching or repositioning them for the sake of comfort. Hostility is expressed when a Bildir seals their nostrils and folds their mouthparts tightly together, pointing their snout straight up to direct both of their book eyes at the subject of their violent intention. Attacks usually consist of blows delivered with the elbows or heels if the Bildir is not in possession of a weapon.
Modern Bildir are a fully developed spacefaring species, respected internationally for their ground, EVA, and navy fighting ability combined with their lack of "warrior" tendencies that make many similarly combat capable species a liability in security work. Bildir' speed, power, and agility allow them to go toe to toe with species such as Tortogs at intimate range, but will always do so with the primary goal of finishing the fight and retiring to a cabin near a river delta rather than letting the fight be prolonged for spiritual or entertainment purposes.
One exploitable weakness of Bildir is that they cannot see things that are above their head because of the positioning of their book eyes.
