No, not at all :)
I was thinking about a strategy based on what the Splerions usually do with the feromones. If they have the best olfact (needing only a molecule for detection), why not the Mystacinidans having the best hearing? :)

I actually thought that they would release molecules into space and therefore use a echolocation on that range. I just didn't know how feasible it could be?
If the Splerions can, then the Mystacinidans can have it too. They're bat related anyway :D

Different senses, but the same basic strategy. That's how I looked at it.

I'll take that explanation and declare you my official plothole fixer.

Hahaha :)
Glad you liked it.
