Gasfoot

Gasfoot are Genelsia's most ubiquitous apex predator.

Description
Gasfoot are Genelsia's most dangerous apex predator. They are solitary hunters, roaming the plains in search of their next meal, usually an Inepta or Grossbark, which they kill during an almost always fatal, short and furious pursuit. Most often, they can be spotted concealing themselves among beds of trophytes, where they take advantage of this colonial fauna's electrical discharges to discourage herds of Grossbark from getting too close to them. To aid in their camouflage, they have adapted an organic sonar system which emits ranging clicks and pings in concert with these discharges to obscure its point of origin from its intended prey; however, this sonar also has a use in attack, allowing them to terrify their intended targets to likely cloud their judgment.

They stand and walk about on a single pair of large, muscular, two-toed legs. They also have two muscular limbs coming out of their sides and facing backwards. These limbs can be pulled forward to make the Gasfoot look bigger and more intimidating, whether to scare away a possible threat, or as a courtship display. For personal defense outside of hiding among trophyte colonies, they have developed a symbiotic relationship with some unspecified microscopic organism, allowing them to utilize bio-luminescence. These bio-luminescent patches are aligned on their backs, and are used when attempting to frighten away enemies (if any). The Gasfoot also has a retractable appendage in it's mouth that it uses to attack and subdue prey. This pierces the victim's skin and injects digestive juices into the body at a fast pace. It then uses it's powerful jaws to consume the now soft flesh of it's prey. Since all fauna on Genelsia have hard skin to protect them from the elements, Gasfoot need this stomach acid technique to kill and eat its prey quickly.
