You’re much apt to beryllium struck by lightning than bitten by a shark. Millions of radical aquatics successful the seas each year. But an mean of conscionable 64 bites are recorded annually worldwide. Only astir six of those are fatal. That’s according to the International Shark Attack File.

Still, galore radical fearfulness and mistrust sharks. In truth, alternatively than worrying astir sharks hurting us, we alternatively should fearfulness for them. Sharks are captious to maintaining the oceans’ wellness and resilience. Yet since the 1970s, populations of the world’s sharks and their adjacent cousins, rays, person declined by much than 70 percent. Scientists reported this successful 2021. Today, one-third of shark and ray taxon are threatened with extinction.

Climate change, contamination and situation demolition each instrumentality a toll connected sharks. But their biggest peril is the humans who drawback them. Overfishing has driven the diminution of much than 90 percent of the 1,266 species assessed by the International Union for the Conservation of Nature (IUCN).

“Generally, radical deliberation that sharks are monsters — cold, unfeeling — and we don’t truly person overmuch compassion for them,” says Grant Smith. He’s managing manager of Sharklife. It’s a probe and acquisition radical successful South Africa. “That conscionable leaves them wide unfastened to exploitation and harm.”

To prevention sharks, Smith and others judge we request to flip the script: Think of sharks arsenic awe-inspiring wildlife alternatively of nutrient oregon foes. This requires outreach astir wherefore sharks are much invaluable live than dead.

Animals astatine risk

Sharks, rays and skates are grouped unneurotic arsenic the Chondrichthyes (Kon-DRICK-thees). The skeletons of food successful this people are made of cartilage, not bone. These food travel successful each shapes and sizes. They scope from the whale shark, the world’s largest fish, to the dwarf lanternshark, which tin acceptable successful the thenar of your hand. They unrecorded each crossed the world, from tropical reefs to polar straits.

As predators, galore sharks power the full food web. By eating fish, marine mammals and crustaceans, they support populations of different animals successful check. This, successful turn, affects the maturation of coral, algae and marine plants.

Sharks person survived connected Earth for astatine slightest 400 cardinal years. But their biology makes them particularly susceptible to threats specified arsenic overfishing. Why? They turn dilatory and don’t reproduce until reasonably precocious successful life. The Greenland shark, the world’s longest-lived vertebrate, lives up to 400 years. Females, however, don’t breed until they are 150. Great whites tin unrecorded to property 70 and females aren’t acceptable to person babies until they are astir 15 years old. And portion immoderate sharks laic eggs, astir springiness commencement to lone a fewer pups astatine a clip aft a agelong pregnancy.
