"exponentially in size" Are you sure you mean to use that word?

Is "fat, hairy sausages" becoming some kind of textual meme?

" their life." That suggests the singular "they", when "their lives" makes more sense.

" Similar" A word's missing. "Similar behavior", perhaps?

I like its art and concept design. I also like how the displays are adapted to echolocation.

Yes, I did use "exponentially" intentionally.

"Fat, hairy sausages" is the best description I can think of for what the larva looks like at that stage. There's an illustration of it in the ancestor and it's quite accurate.

I've fixed the errors.

I like how you can just barely make out the orange-red hairs on the larvae. Let's you know what will become of it in the future.
