  • It is possible that the tusk itself could be used as a pressure transducer akin to the ampulllae of Lorenzini or lateral line of a fish to sense movement within the water column for depth, salinity as well as electric field of prey. As a dentist, one appreciates the piezo electric effect of dentin and cementum. The tusk could easily be akin to a piezoelectric beam type transducer that could register how much force a opponent could apply like in a jousting contest, and stave off injury by noting the amount of force that is being applied to the tusk. The human tooth is capable of sensing in six axis micro movement of 5 micron. The bone to tooth interface of the periodontal ligamant would be the gross input and the length of the tusk is a force amplifier with exquisite fine descrimintation. EXCELLENT Video....... Cheers.

  • Maybe it's also like a sensory organ for hunting? When something moves, that movement ripples out and moves water along the tooth at a different rate than if there had been no movement. That different flow rate might register to them as a change in salinity, similar to how the movement of air from like a fan or something can register as a difference in air temperature to our own skin. The tooth could be an alternative to echolocation for hunting scarce bottomdwelling prey and cephalopods in very deep, dark water. One that's also much more energy efficient, because the animal doesn't have to produce very loud sounds. I don't think it would otherwise make sense for additional salinity to the tooth to trigger an elevated heart rate, as that would just mean that the narwhal consumes even more oxygen right when it is about to become much harder for it to breathe. It would also lead the animal to *avoid* breathing holes in the ice, because that's where ice growth is going to be the most intense (cold air meeting liquid water) and thus salinity will be too.

Squeaky chair or something. I'll never understood American fascination with inferior, undemanding under-belt jokes. This is what makes most Hollywood 'comedies' unwatchable. Consumers are stupid and least common denominator is everything is the movie industries mantra. Although their fascination with sexual, genital and excreaton and fart related is understandable, seeing the us is a military superpower accelerating towards it's end. Same thing happened in the imperial Roman empire (and it is also the reason of their SJW and gender and race hysteria imo). Good for China and Russia, I guess.

If they did, then that might be a point in favour of the idea that narwhal tusks are just mutated versions of a preexisting trait.
