Sharks are predatory fish that strike fear in people with their appearance and even make us feel like they are going to attack us from the depths every time we enter the sea.
We have all had this scenario in our minds, especially when swimming in areas with great depth. This scenario is indicative of the impact the movie industry has on us. If you have watched horror-thriller movies where sharks are used, this situation has become ingrained in your subconscious and it is not easy to get rid of it.
Sharks are the most predatory fish in the sea. They feed mainly on meat and invertebrates, but they have been seen eating things thrown overboard.
In the stomachs of some captured sharks, objects such as tin cans, pieces of glass, newspapers, pieces of wood were found. As can be seen from this, they do not discriminate food, they are the scavengers of the sea. They spend all their time looking for food and they can also eat creatures bigger than themselves.
