It's shark week, that seven day period every summer when our television screens swim with stories of one of the ocean's most fascinating residents. But sharks make headlines all year round. Here are some of the coolest shark stories EcoWatch has come across this summer.

Two separate shark attacks took place this weekend about 110 miles apart on Florida's Atlantic coastline, leaving two men injured, according to ABC News.
More than a thousand sharks and rays have become entangled in jettisoned fishing gear and plastic debris, a new study has found. The researchers behind the study warn that the plastic trapping the sharks and rays may cause starvation and suffocation.
These related species — which, along with chimaeras, are known collectively as chondrichthyans — include some of the most threatened marine fishes in the world. Sharks and rays face a variety of threats depending on where they live and swim, but the biggest risk comes from overfishing, which takes a noticeable toll on these slow-growing, slow-to-reproduce animals. As a result, nearly 1 in 4 species of chondricthyan fishes is estimated to be, or assessed as, threatened, according to the IUCN Red List.

Hawaiian lawmakers and conservationists are pushing for a landmark law to protect the Aloha State's sharks and rays.
House Bill 808, which outlaws the intentional killing, capture, abuse or entanglement of sharks and rays in state marine waters, passed its first committee meeting on Wednesday. The upper chamber version, Senate Bill 489, secured its first committee approval late last month and passed a second reading on Monday.
Sharks, rays and chimaeras are some of the most threatened fish in the world. More than 50 percent of species in the Arabian Sea are at elevated risk of extinction due to coastal development, overfishing, pollution and habitat destruction. According to an expansive new study, spanning more than a dozen countries, species like sawfish are particularly hard hit with extinction or local extirpation.

Just over three years ago, I was clinging to a rock in 20 meters of water, trying to stop the current from pulling me out to sea. I peered out into the gloom of the Pacific. Suddenly, three big dark shapes came into view, moving in a jerky, yet somehow smooth and majestic manner. I looked directly into the left eyes of hammerhead sharks as they swam past, maybe 10 meters from me. I could see the gill slits, the brown skin. But most of all, what struck me was just how big these animals are—far from the biggest sharks in the seas, but incredibly powerfully built and solid. These are truly magnificent creatures.

On a sunny Saturday in mid-September, 26-year-old Arthur Medici was boogie-boarding in the waves off Wellfleet, Massachusetts, when a great white shark bit his leg. Despite the efforts of a friend who pulled him ashore and the paramedics who rushed him to the hospital, Medici died from his injuries. It's about as tragic a story as you can imagine: a young life cut short due to a freak run-in with a wild animal.
Marine scientists discovered a very rare
shark nursery about 200 miles west of Ireland and shared a mesmerizing video of the find.
Back in July, the government-supported
Marine Institute's SeaRover survey found a large school of blackmouth catsharks and what appears to be thousands of their egg cases, also known a "mermaids purses," at depths up to 750 meters (2,500 feet).
