True. But the show also deals with creatures whose existence defies physics, magic, superpowers and a energy source that cannot function when it leaves the planet. Most people's won't understand enough about scorpion anatomy and biology to care. Now obviously that doesn't excuse design laziness but, given all of the above, it's not a huge issue.

And that's without other little things, like Neptune's surprisingly safe plasma gun, teenagers engaging heavy combat work, international wars launched between countries separated by significant geographical hurdles (not to mention the ever present Grimm threat), a species that is surprisingly akin to humans but for animal features (the probability of that is incredibly low) and curious socio-political organisation (for a society living under an ever present existential threat, Vale seems surprisingly liberal. I'd expect a more conservative, militaristic, collectivist society which the show doesn't seem to indicate is the case).

So while I do agree Tyrian's tail doesn't stand up to scrutiny (without changing it such that it isn't a scorpion's tail any more, it just looks externally similar), I'm willing to let it pass.
