Calidiuedraco pinguis
Descended from a population of Draco brunus that became established in Zone B, Draco pinguis has developed a variety of adaptations that better enable it to thrive in the cooler climates. It has become mesothermic, speeding up its metabolism to have its body temperature raised five degrees Celsius (5°C) above the ambient temperature when it is below eighteen degrees Celsius (18°C) to keep its proteins from slowing down and freezing, and to be able to digest food in a cooler climate. Its body is also more stout to slow down changes in temperature and to insulate any produced heat, and it has many dark stripes along the body which absorb heat.
Living in an area less tropical with less food and having an increased demand in food, Draco pinguis has become less picky on its diet as a result. Hatchlings and juveniles will feed on the seeds and stems of Lorensia clearensis, Megaplortatus sustensa, Megaplortatus stellafrons, and Crooksoluis yellionuis that are on the ground while adults prey on Vermislontus drillus, Vermislontus cocotus, and Terroslontus lignumpurpla as well as any unoccupied carcasses they come across and smaller juveniles of their species and Draco brunus. If there is a lack of food they can find at the surface, they will use their claws to churn into the surface of the soil, hoping to dig up any Vermislontus drillus or Terroslontus lignumpurpla that may be hiding. Injured Aerialslontus odonta and Aerialslontus flectopesus that have fallen onto the ground are also on the menu.
Draco pinguis typically grows around sixty centimeters (60 cm) in length, being relatively small compared to other "large" muscals in order to conserve what energy it has in this "low-energy" environment, while still being large enough to thermoregulate, as a form of gigantothermy. Even though gigantothermy would help it to better maintain its body temperature, growing too much larger will make it require even more food, so its food demands keep it at a rather small size at this time. As they live in a colder range, their mating season is at the end of spring so that their eggs can survive in the summer, when it is the warmest. The eggs take three (3) weeks to develop and hatch in a ditch-nest, and they take another six (6) weeks to fully mature. Around thirty (30) eggs are laid but only a small number survive to maturity and reproduction as they can be eaten by adult individuals or can be preyed on by opportunistic wyverns such as Dracuanguilacerta audioacrus, Dracowyverious raptordracornis, Draconiraptor tromerovenator, and Terroraptorus raptoratus.
