With 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.
