It always amazes me how these little burrfish (and porcupinefish) can just devour live fiddler crabs. Those things have a huge claw which bite really hard. But the burrfish just grab the thing and with no fear, eat the thing parctically whole.
The bites don't seem to bother them but their eyes are vulnerable. I usually break off the bog claw of the crab, the fish don't mind but I want him to keep both of his eyes
Grabbed one of those porcupine fish last year by hand while it was swimming by and lossened my grip for a second and the sucker turned around and gave me a big thank you by biting a good chunk of my finger. Kinda hurt.....
