Green behemoth newt and green mossanewt: 2 speculative species of newt that live their entire lifes under water. The green mossanewt is, as its name suspects, a kind of hibrid between a newt and a mossasaur; so this is the apex predator of the under-water bioms which has a length of 11 m, or the same as an European minibus. The green behemoth newt is its pray and it is bigger than mossanewt, with 21 m at max; that is due to the green behemoth evolved convergently with barbed whales of Earth, filling the niche of passive predator of the oceanic bioms. One last thing of this species is that the green shade of skin actually comes from a mutual relationship with algees, which have transport and new food saurces only with retire the salt from the transpirable skin of gigant newts.
