Sharks, bank robbers, roller derby—this upcoming week is distinctly fierce. Kick it off with the Shark Week finale at the Cabrillo Marine Aquarium, which includes a dissection and live feedings, then ride the high-octane wave through a derby bout and a screening of a documentary about the Dog Day Afternoon bank robber. And as always, check Groupon for even more great things to do in Los Angeles. Shark Week San Pedro | Saturday, August 9 Though it's the last day of Cabrillo Marine Aquarium's Shark Week celebration, Saturday is arguably the most eventful, with a screening of the short film Surviving Sharks, live feedings, and a dissection and specimen display. (3720 Stephen M. White Dr.; $1–$5) LA Derby Dolls Baby Doll Brawl Echo Park | Saturday, August 9 There’ll be plenty of action on the track during this matchup between the Bad Hatters and the Cheshire Cats, but come early to hear live music, grab slices of Garage Pizza, shop Stila Cosmetics, and sip craft beers from Golden Road Brewing before the Filipinotown venue possibly closes this fall. (3720 Stephen M.

Pay extra for varying levels of early VIP admission, and get first dibs on this month’s wares. (1001 Rose Bowl Dr.; $8–$20; free for kids 12 and younger) The Dog Melrose | Through August 14 Nearly 40 years after the release of Dog Day Afternoon comes this documentary about the late John Wojtowicz, the bank robber who inspired the Oscar-winning feature film.
