I'm just curious after noticing how similar some of them look:

Basically, the one variant of Lamia, very much resembles the Ananta. Having the same tail, similar facial features and heck, even the same style of clothing.
The only major differences being the hands being more claw-like on Lamia and the "Hair" being more akin to a Cobra's hood.
Of course, the other Lamia seem much more aquatic in design. With more fish-like scales and a fin on the end of their tail with more fin-like facial/hood features.
Was this accidental or intentional?
Given that for the Fractal Continuum (Hard) we find out that [SPOILERS]
Ixal were failed Allagan experiments
Is something similar true for Ananta?
Or is it something else? Such as Allagans trying to recreate them? Or pure coincidence?
