Um.. the beach ones are a hoax haha they have the series of fake mermaid photos also. Those bones are actually grafted and glued on with a variety of bones from animals and different types of fish.
The fish with the needle-like teeth and huge jaw is probably real haha, those are deep-sea fishes so i doubt they'd end up in a fisherman's net, scientists have real trouble accessing these deep-sea areas, let alone fishermen. I've seen photos like this before though!
