english: It's what's known as a bioluminescent burglar alarm, and just like the alarm on your car or your house, it's meant to cast unwanted attention onto the intruder, thereby either leading to his capture or scaring him away.
non_english: Tento jav sa nazýva bioluminiscentný poplašný systém. A podobne, ako alarm na vašom aute, či dome, má to prilákať pozornosť na votrelca, buď aby sa ho podarilo chytiť, alebo ho vyplašiť.
