The leteti split from its ancestor, the hexcrawler. It now feeds exclusively on the airbulb and its decedents, and other, softer organisms. It has the ability to fly, albeit for short distances, by using three pairs of its flat, flipper-like appendages to push at the air. The top two of its breathing tubes have expanded greatly, have the ability to be closed, and are filled with ammonia from the airbulbs. This extra lift, along with the force of its appendages and Mason's weak gravity, allow it to float from one patch of airbulbs to another, avoiding predators and moving more quickly than its land-based relatives, although it has to land often to "refuel" and during the winter, where it will curl up inside the cavity of a folded folding airbulb to spend the night.
To better help it sense its environment, two of its primary oral tentacles have become specialized, developing their ancestors ability to detect heat much further, so when displayed allow the organism to spot individual flora and fauna. They are covered in a thick, gelatinous layer that is in turn enclosed by a thin membrane. The amount of disturbance on the membrane by infrared radiation is amplified through the gel, and picked up by the modified touch-sensors. The rest of its primary oral tentacles are similar in form and function to the teci, with the tentacles curled in its mouth until ready for use. Two of its body appendages have atrophied slightly, and are used to grasp the bulb of the airbulb by puncturing it slightly, enough to get a grip. Its gelatin-like eggs are laid inside of airbulbs in the fall, so that come spring, they will have an easily accessed food source available.
