Sailshell

The sailshell split from its ancestor the migrating glowsnapper. They have grown double in size and has adapted to life on land. Unlike their ancestors they do not make their way to the sea but make their way onto land. The adults will lay their frog-like eggs in Yokto Mountain Lake. Unlike their ancestor they do not die after mating. Once the eggs hatch the tadpoles will eat pioneer twinkiirobranch and spread to the nearby Yokto Moor. The tadpoles look much like their distant ancestor the volox carpotesta luceremundare and are only around 4 cm long. Once they get bigger they will eat the yokto crystal until they have developed their legs and lungs and can come onto land.

Once on land they will eat the forest venomerald for their rest of their lives. When the adults reach sexual maturity will migrate back to Yokto Mountain Lake to mate and lay their frog-like eggs in the water. Since they are not very good swimmers at this stage of their lives they must wade in the water. The males will attract females by flashing their bioluminescent spots. Like their ancestors the males grow tail spikes once sexually mature. The males will battle each other by thrashing their tails, clawing, and biting each other. Most of the time they are just threats and no one gets hurt, but sometimes among equally matched males some will die. After the mating season the male's tale spikes will fall off and they will grow new ones next mating season. It takes them around 10 years to reach sexual maturity.

Their shell now forms sort of a sail which helps regulate their body temperature. It is made of bone and hardened skin. They will stand with their sails facing the sun in order to warm up faster since there are many blood vessels near the surface. While ridged it is not very good for protection anymore. In addition those with larger sailshells are more attractive to the opposite sex.
