W ith a record 19 hours of primetime programming planned for this year, Shark Week has never been a bigger beast.
To celebrate, Discovery is diving deep into the annual summer TV event’s history with Shark Week Sharktacular , premiering Tuesday, June 23 at 10 p.m. The hour-long special, hosted by actor-director Eli Roth, will count down fans’ favorite moments from the past 27 years and sink its teeth into fan-submitted viral shark videos.
One of those viral videos, above, offers an alarming lesson for shark enthusiasts: shark-proof cages aren’t always shark-proof. “There are circumstances when the shark swims at the right angle that it just finds itself in the cage,” says marine biologist Tristan Guttridge. Because sharks can’t just swim backwards out of the cage, they try and free themselves with a death roll, putting divers at serious risk for harm.
“Now you’ve got a blender,” says shark researcher Michael Domeier, “with divers in the blender.”
See what happens when one shark gets stuck in the footage, above, and catch Shark Week when it returns July 5.
Three Shark Photographers You Need to Follow The water column is a three-dimensional habitat for sharks. Instead of traveling horizontally across the ocean, many species, like blacktip sharks, bounce up and down, repeatedly descending and ascending through the water column, in hopes of picking up any signs of prey. Aliwal Shoal, South Africa. Thomas P. Peschak A Red Sea Silky Shark.
To survive in the vastness of the open ocean, Silky sharks rely on their boldness and curiosity to investigate every opportunity that might yield a meal. Sharks make up for their lack of hands to investigate things, with thousands of tiny pores, called the Ampullae of Lorenzini, which line the shark’s snout. Northern Red Sea. Thomas P. Peschak The whale shark is the world’s largest fish, born with unique spotted skin patterns, which don’t change significantly as the animal ages. Scientists are using the latest in space technology developed by NASA, for fingerprinting and identifying whale sharks based on their spots.

Peschak Bronze Whaler sharks are the most abundant sharks during the sardine run off South Africa’s east coast every June/July. Hundreds of them patrol the margins of baitballs and charge into the seething mass of fish singly or in small groups to feed. Thomas P.

As he is frequently asked if he is afraid to go back to the water after the attack, Coots has no doubt: “I am positive I was attacked as mistaken identity and the last couple of days [swimming with the sharks] really reiterated the point. Humans are not sharks' prey.” Mike Coots While babysitting his 6-year-old nephew, the little boy showed the toys to Coots. "It's you uncle Mike," he said. Mike Coots Coots has been able to return to surf after the shark attack, wearing a prosthesis for his right leg. Coots was just a teenager when a tiger shark attacked him in the deep water of Kauai, an area known to be populated by sharks. Mike Coots Coots took this photograph with Hero3, a waterproof camera. He observed the white shark being hesitant before eating its meal. “Incredibly beautiful to watch and I never felt threatened once. Completely serene,” Coots wrote on his Instagram feed.
