It is pretty fast tho, the big slow empi engies even move the right kind of lazy. It could be a maggot, just imagine it cocoons up and suddenly turns into a butterfly
We could also think about earths’ early prehistoric past, when we had lots of huge reptilians swimming our oceans.
I think a lot depends on choice of weapon and playstyle as to how you would compare each ship to an animal. My gauss tacklers I would compare to a scorpian, with sudden, very painful, killing attacks, whereas jeri tackler with gravi-beam and slowing missiles and mods I would compare to a spider, using it’s web to paralyse and enemy and slowly kill it.
Same with gunships: bubble gunship would be eagle, diving in for its prey in one swoop, whereas a gauss gunship would be more of an chameleon, using its long tongue to catch prey far away.
