Splitting from its ancestor, the namnoboros has undergone several physiological changes. The most prominent of these, outside of a change in coloration, is the presence of chitinous sheaths encasing the end of each tentacle making up their beak. These "pseudo-fangs" aid the namnoboros when it comes to holding prey by piercing into their hides and holding them long enough so that their beaks can bite and tear into them. This has made this species a far more formidable hunter, a lifestyle which they have now fully embraced.

The namnoboros has developed a relationship with the krelp. Females will often climb along the stalks of these aquatic crystals, keeping them clear of most epibionts, and will lay their eggs upon them. Their skin color has taken on a shade of red in order to help them blend in with their new homes. The only part of them which isn't red is their fleshier gills which now extend from beneath their gill flaps. Flush with blood, they take on a purplish hue as they take in oxygen and release CO2.

A surprising evolutionary development has occurred within the eggs of this species, having come about due to occurrence of a symbiotic relationship between themselves and a strain of the algae-like genus known as Binucleus Pseudo-Cyanobacteria. Having arisen from a chance contamination of a clutch of eggs, the resulting symbiotic relationship proved a fruitful one. The microbes secrete excess sugars and the like which the developing embryos can utilize, which in turn has lead to a faster developmental cycle compared to that of its kin. The egg, meanwhile, provides the microbes a secure shelter and, as time passes and the embryo matures, a source of waste to fertilize the algae-like species with.

While one would expect this relationship to end with the hatching of the egg, the opposite is in fact true. The microbes will often become embedded within the flesh of namnoboros, and will stick with it for the rest of its life. While the relationship at this point becomes more parasitic than symbiotic, once the namnoboros mates, the colonies of both individuals will intermingle and exchange genetics while their hosts do as well. Strains from both colonies will eventually make their way into the eggs as well, starting the cycle anew by helping to contribute to the growth and potential for survival of future generations.
