Shark ocean menacing

Sharks are ancient marine predators that inspire both fascination and fear, with over 500 species distributed across the world's oceans.

About this subject

Sharks are cartilaginous fish that have existed for over 400 million years, long before dinosaurs. As apex predators, they regulate prey populations and maintain the balance of marine ecosystems. From small deep-sea species to the enormous whale shark, each plays a specific role. Despite their 'killer' reputation, unprovoked attacks on humans are rare: on average, about 70 incidents per year, with fewer than 10 fatal. Far more people die from drowning or bee stings.

Popular culture amplified the threatening image of sharks, especially after the film 'Jaws' (1975). However, many species are threatened by overfishing, finning, and habitat degradation. About one-third of shark and ray species are at risk of extinction. Conserving these animals is crucial because the absence of sharks can trigger collapses in oceanic food chains.

In Brazil, several species are recorded, such as the bull shark and tiger shark. The Brazilian coastline, especially areas like Fernando de Noronha and Abrolhos, serves as nursery grounds for some species. The presence of sharks is an indicator of marine health. The 'lo-fi disposable camera' aesthetic adopted in some contemporary representations aims to capture the rawness and unpredictability of the encounter, contrasting with traditional cinematic views.

Frequently Asked Questions

How many shark species are there?

There are more than 500 known shark species, ranging from the small lanternshark (about 20 cm) to the giant whale shark (up to 18 meters).

Do sharks frequently attack humans?

No. Unprovoked attacks are rare, averaging about 70 incidents worldwide per year. Most are exploratory rather than predatory.

Why are sharks important for the oceans?

As apex predators, they control prey populations, maintaining ecological balance. Their removal can cause imbalances in entire food chains.
