I was told these things are VERY fast, very difficult to kill, and after they escape they avoid divers. REEF has study data; opine all you want, you're still wrong. This is why REEF came up w/ the bag system to catch them. Also, since lionfish learn to avoid divers, after all the no-aim-but-take-my-speargun-anyway-to-compensate-for-my-teenie-weenie guys give up failing to kill them, it will be more difficult for the people who actually know what they're doing to eradicate the species. But, hey, thanks for playing.
These guys clearly have superhuman powers....
