Ruminasqualus lepidoptera
Ancestor: H. Rotundus
Zone(s): 4 and 6 as they migrate from zone 4 to zone 6 which is where they spawn
Size: 30cm long
Reproduction: they lay about 10-20 eggs and have a slightly elongated internal development as they hold the eggs inside until they get to zone 4 and they mate via a cloacal kiss. They have developed this internal fertilization in order to better protect the developing embryos
Food/Sustenance: adults feed mostly on the giant polyphs in zone 4 while juveniles will remain in zone 6 until they have matured in the meantime they feed on T. extensiensis and other various Taxonomum and after a period of 3-4 years they mature, this is so the adults avoid competing with H. ungulodontus and their own offspring
General description: H. lepidoptera is similar to H. Rotundus. In that it primarily uses its front 2 pairs of pectoral fins to provide propulsion while the rear pair help steer. In lepidoptera the pectoral fins have elongated as an adaption to their long migration route to save energy by coasting. Their tail has become shorter to provide a more torpedo shaped body to reduce drag and so predators like Therolamna can’t catch them by the tail. They are weakly countershaded and their top slightly darker than their ancestors while their bottom is slightly lighter.
