Like their parent species Glublekos, Tonblekos can survive in both fresh and salt water. However, rather than staying near one place as both their parent species do, Tonbleko family groups tend to travel between transient water sources, such as tidepools and vernal ponds, whenever food becomes sparse. Adult Tonblekos can be as poisonous as Ranblekos depending on their current diet, and their colorful skin patterns warn would-be predators away. Unlike most amphibians, rather than settle and nest during mating season, Tonblekos continue to travel. To facilitate this, males scoop up their spawn and carry them in their large throat sac, ready to release when they arrive at their next destination. This technique is also used if danger is present, with the male gathering his offspring and finding a safe place to hide until the threat has passed. Although males can produce deep, powerful croaks using their strong throat sacs, females do not have a pronounced throat sac and thus make much higher-pitched sounds.

The creatures that dwell in this rather desolate world still display some diversity in appearance, eating habits, and social behavior. Whether they have fur or feathers, skin or scales, their unique genetic makeup allows for a variety of colors and markings within each species. Despite limitations in food sources, herbivores, omnivores, and carnivores are all present in the food chain, and each species requires specialized care within a laboratory. Although the artificial setting of housing units and breeding pods precludes most opportunities to study true interspecific behavior, the interactions within and between species has been studied extensively in the wilderness by scientists daring enough to venture beyond the outpost’s walls.
