Shark sightings have been increasing along the East Coast as Americans seek relief from the summer heat at the beach. Recently, Rockaway Beach in New York was temporarily closed after a rare shark attack resulted in a woman being hospitalized. In Massachusetts, multiple shark sightings prompted the closure of Marconi Beach to swimming.
To provide some interesting facts about sharks, here are 12 statistics related to their population and size:
1. There are over 400 different species of sharks found in seas worldwide.
2. Marine experts estimate that there are approximately one billion sharks in total, which means there is approximately one shark for every seven or eight humans.
3. Sharks can be found in all oceans and oceanic habitats, including the open ocean, deep sea, coral reefs, shallows, and beneath Arctic ice.
4. The largest living shark species is the whale shark, with an average length of 46 feet and some reaching up to 60 feet.
5. The world’s largest recorded whale shark measured a staggering 61.7 feet.
6. On the other end of the size spectrum, the smallest living shark species is the dwarf lantern shark, which has an average size of six inches.
7. Great white sharks have one of the strongest bites in the world, with the ability to exert approximately 4,095 pounds of force from their jaws.
8. Most shark species have five rows of teeth, with some sharks having up to 3,000 teeth at once and losing up to 100 teeth per day.
9. On average, there are 72 unprovoked shark attacks globally each year, with over half of the attacks occurring on surfers and board sport participants.
10. In 2022, there were 57 unprovoked shark attacks on humans, resulting in five fatalities.
11. The chances of being killed by a shark are approximately one in 3.7 million.
12. Researchers estimate that 100 million sharks are killed annually worldwide due to destructive fishing practices.
Sharks have been around for an astonishing 450 million years, appearing in the fossil records before the existence of trees. Despite surviving five mass extinctions, one of the largest shark species to have ever existed, the megalodon, became extinct around 2.6 million years ago during the end of the Pliocene era. Initially believed to grow up to 98 feet long, recent studies estimate that megalodons were closer to 68.6 feet in length.
In conclusion, sharks are fascinating creatures that play a vital role in marine ecosystems. While shark sightings may be on the rise, the chances of being involved in a shark attack are incredibly slim.
