Aquatic: Nautolans are naturally amphibious, allowing them to breath underwater or above with equal skill. They are fast swimmers, gaining a bonus +1D to all swimming rolls.
Bony Endoskeleton and Dense Cartilage: Capable of handling the crushing pressures of deep underwater, Nautolan bodies are resistant to glancing blows, gaining +1D to resist impact damage such as punches and clubs, but offering no help against cutting weapons or energy weapons.
Low Light Vision: Nautolan eyes can see extremely well in low light conditions, giving +1D to compensate for low light conditions. However this offers no help in full darkness.
Non Verbal Communication: Nautolans can communicate without words with each other, by non verbal means such as reading the swirls in each others eyes, and sensing pheromones. While some of this may be spotted by other species, much of it is beyond the sensing capabilities of non-Nautolans.
