Constant Smile - stock photo

It seems like one of the sharks in the photo smiles. Unfortunately, it does it not because of a good mood. A fish hook pierced its mouth the way that the face was frozen in this grimace. With the help of this picture I want to draw people's attention to the problem of a human impact on the inhabitants of the underwater world. From the hundreds blacktip sharks, that I met in South Africa, every second had a piercing on its body: in the mouth, or eyes, or fins.
