@georgia Nah it’s really just the aesthetics imo, many animals prefer aesthetics aesthetics over utility like colors in birds so that may make sense
@Meeper @georgia Evolution is not an optimizing process, at least when it comes to the ability of the individual complex organisms. The species don't survive cause their members were the bestl, but cause they were barely good enough, or sometimes barely bad enough. Being very good at harvesting, means also being very good at depleting. This gives ample space or random wacky things to exist.
At R&D headquarters of evolution: OMG, the crab we made is just too freaking fast for its own ecosystem, what to we dooo, we can't change the entire design, the deadline is tomorrow!! ok, we just make the pincer huge.... we just make the pincer huge and it's not so fast anymore... ok, it's fine ship it!
