Question Scientific Accuracy - Advantages and Complications of Tetrachromacy Underwater
I have devised a semi-aquatic sapient species known as the Hexapi who until now I thought were trichromats. However, after doing my research on the evolution of the eye, I found out that colour vision may be a disadvantage underwater. As I didn't want to give them polarised light vision, I decided to...

Question Scientific Accuracy - How can we make an alien brain more 'efficient' than a human's?
I am designing an semi-aquatic sapient species known as the Tetrapi. They have an appearance similar to that octopi, only with 4 tentacles comprised of 3 opposable digits. Unlike octopi, they are air-breathing and show full control of their behavioural responses. They are at a technological level of ...

Question Which protein is more efficient at oxygen extraction for an AIR BREATHING aquatic species? Haemoglobin or Haemocyanin?
Another question concerning the Tetrapi, I would like to know if having haemocyanin-based blood (copper-based blue blood) would be an advantage over having haemoglobin-based blood (iron-based red blood) for an air breathing aquatic species. Is the fact that the majority of animals have red blood grou...

Question Scientific Accuracy - How could Homo Sapiens effectively communicate with this aquatic alien?
I have designed an alien species similar to octopi (Tetrapus Sapiens) who live in the tropical waters of a fertile, lush world known as Iridia. The octopi (more like tetrapi) have moved past the hunter-gatherer stage of technology and are currently at a technological level similar to the first Mesopo...
