Hahaha. What a ridiculous weirdo.
I like it.
"testament to their endurance" A testament to their endurance.
" offspring eat" Do you mean to separate the adult and juvenile/larval diets? If so, I recommend: "Carnivore (Adults: Bejeweled Emperor Scylarian, Needlenose Scylarian, Vicious Seaswimmer; Juveniles: Charybdis, Redbone Gilltail, Speckled Spinderorm, Hanging Necarrow)"
I still have to fix the Redbone Gilltail. It turns out Redbone Gilltails never had bones. I should be fairly easy to just give it a striped pattern suggesting bones. Since it's not impossible to salvage, you don't need to remove it from this fauna's diet, although it may delay approval somewhat if it takes too long to fix the Redbone Gilltail.
