Greererpeton did not follow the other tetrapods onto land, instead it remained as an aquatic predator. Support for this style of life comes from poorly developed hearing, evidence of a lateral line (sensory apparatus found in fish), reduced limbs and an extended spine giving it a more eel like appearance. This suggests that there was plenty of prey to be found in the waters of the early carboniferous and that Greererpeton had specialised in hunting it.
