Skekfish, also known in common parlance as "knife-fish," were compact, tunneling predators that engaged in pack hunting.
Skekfish exhibited a unique blend of carbon- and silicon-based biology. Each specimen measured between 30 and 40 centimeters long. The skekfish possessed a covering of numerous rows of minute, incredibly sharp, metallic fin-scales that facilitated movement during burrowing. Four rudder-fins, spanning the length of its body, enabled directional changes, creating the illusion of swimming through subterranean environments. Skekfish demonstrated the capability to tunnel through both wooden structures and solid rock formations. Lacking visual organs, skekfish relied exclusively on auditory and vibrational cues to locate prey.
The skekfish's composite physiology demanded the intake of both soil and animal matter for sustenance; an adult skekfish would face starvation if deprived of animal flesh for more than 48 hours. Skekfish launched attacks by emerging from the ground in coordinated formations, propelling themselves directly toward intended targets. Their feeding process involved burrowing through the flesh of the victim.
Skekfish originated from eggs, attained full maturity within a single day, and displayed a propensity for swift propagation. Skekfish colonies possessed the capacity to inflict severe ecological damage upon an entire [planet](/article/planet-legends] in short order. Upon depleting available biomass, adult skekfish deposited egg clutches within the bodies of their final prey, subsequently concealing these nests beneath a layer of newly displaced soil. Skekfish eggs exhibited viability for millennia (years), hatching only when disturbed by the presence of new animal communities.
