Howdy! I'm a HUGE fan of crustaceans and my favorite one is The Mantis Shrimp. It's a rainbow colored shrimp the size of a lobster that shoots under water shockwaves with their action spring claws. It's attacks are so powerful that upon impact it generates light and heat around the blast zone. I was wondering if that was in your project's timeline at all (perhaps as a stretch goal) since they're the best.
