The Spineless Toadtuga split from its ancestor, the Toadtuga. It has moved the Dixon-Darwin Boreal like its relative the Thorny Toadtuga. However is much more aquatic and tend to stick to the waterways of Dixon-Darwin, except Blocks. They have developed larger lungs to help them hold their breath underwater for larger periods of time. Like its ancestor is a solitary opportunist. and will sit motionless underwater for prey to pass by. They depend upon their 6 eyes to spot prey.
Their light yellow coloration helps them stay hidden in both the white soils of Dixon and the golden soils of Darwin. Those in Dixon tend to be more golden, while those in Dixon tend to be more white. Their spines have disappeared to help them resemble rocks more. Their mouths have gotten much larger to help them gulp up prey. They even have a throat pouch to help hold both the prey and water when gulping.
Males will wrestle against each other to impress females during mating season. Once the rival is defeated the male can mate with the female in the water where she deposits her eggs. Much like how salmon externally fertilize their eggs. Adults play no part in raising young. Thus the tadpoles must fend for themselves when they hatch. Most subspecies do not leave the waterways but those that do venture out to the Boreal regions stick to small ponds and puddles.
