Normally the thorns all over their bodies lay pressed against their bodies, but when the body swelled up, those long and sharp spikes would stand up as well.

This hemp shirt is effective in fighting all kinds of angry fish: When the big spines rise, making the types of fish must be reserved before deciding to attack. Despite being well-protected, but in the water, porcupines are still bait of dolphin and shark.
