Why it evolved

Intensified competition for mates and territory drives selection for increased size and aggressive territoriality. The Haline Overlord has evolved larger dimensions, making it a more formidable competitor and predator capable of tackling the Geothermal Pneume more effectively. Enhanced chemosensory pits allow for better detection of prey and rivals in the low-visibility, geothermally active waters, a crucial adaptation given the world's low light conditions. The trade-off is reduced maneuverability due to less prominent fins and a higher energy demand to sustain its larger size and increased metabolism.
