That’s called humor…. How poor injured seal is telling shark that she is broken so don’t consume….
Anyways, its up to shark to decide….if the shark is “Bin Raider” then its immaterial for shark if seal is broken or not….
For those who don’t understand this humor…. There is a warning on eatable items in supermarkets that if the “Seal” (packing seal) is broken then dont consume that item”…. Here the word Seal is taken for literal sense….. Now you can Laugh!
