Opening day of new shark tank at Seagate Hotel & Spa, 1000 E. Atlantic Ave., Delray Beach; any time; free; 877/577-3242 or www.theseagatehotel.com

In case you haven’t heard, it’s officially Shark Week, aka the best reason to tune in to the Discovery Channel all year long. But it’s worth pulling away from the HD chompers to see some real, live, actual sharks right here in Palm Beach County. The Seagate Hotel, which already has massive tanks devoted to exotic reef fish, jellyfish, moray eels and porcupine puffers, increases its sea-life stature with the opening of a 2,500-gallon shark tank. The 20-foot-tall, 4-foot-long tank will include sharks such as the Japanese leopard, smooth hound and nerf and guitar sharks.


Jason Mraz at Cruzan Amphitheatre, 601-7 Sansburys Way, West Palm Beach; 7:30 p.m.; $23 to $59.50; 561/795-8883 or www.livenation.com

Known as much for his trademark trilby hat and mane of curly dark hair as much as for his music, Jason Mraz rose through the pop music ranks the way you’re supposed to: by playing coffeehouses for peanuts, finding bandmates, releasing an independent album, being discovered and continuing to release good records, each one selling more than the one before it. It’s pretty textbook when it’s done right, and Mraz is a role model for doing it right. He’s had a number of smash hits, none bigger than “I’m Yours,” which you cannot stay at a karaoke bar for more than 15 minutes without hearing. The sensitive pop-rocker’s latest album is titled “Love is a Four Letter Word,” and he arrives in South Florida to promote it alongside opening act Christina Perri.


Food for the Poor Kick-off Party at World of Beer, 4337 Lyons Road, Coconut Creek; 6 to 9 p.m.; free; 888/404-4248 or www.foodforthepoor.org/walk

Plans for the event are now under way three months ahead of time, and there’s no better opportunity to sign up than at this kick-off party. The free event will feature live music, raffle prizes and drink specials. World of Beer is known for its extensive list of libations, including such summer recommendations as Kolsch, American Blonde, Cream Ale and Saison.


Boca’s Ballroom Battle at Boca Raton Resort & Club, 501 E. Camino Real, Boca Raton; 6 to 10 p.m.; $150; 561/347-6799 or www.scholarship.org

Some of our city’s top luminaries will shake their moneymakers alongside professionals from Fred Astaire Dance Studios at what has become Boca’s regional answer to “Dancing With the Stars.” Now entering its fifth year, Boca’s Ballroom Battle has become the signature social event of the summer, with the competitors training for more than four months to win the first place “Mirror Ball” trophy. Tonight’s celebrity dancers will be health care CEO Peter Baranoff, volunteer and former Junior League of Boca Raton president Kristin Calder, JKG Group president Bob Gittlin, Lynn Cancer Institute director Darci McNally, chairwoman and volunteer extraordinaire Beth Osborne, volunteer and charitable advocate Lisa Pechter, President and CEO of the YMCA of Palm Beach County Richard Pollock, and HSBC Securities USA VP Financial Advisor Fernando X. Rodriguez. Proceeds from this fundraiser will benefit the George Snow Scholarship Fund, which provides continuing educational opportunities for deserving, financially strapped individuals.

“Tango Lovers” at Broward Center for the Performing Arts, 201 S.W. Fifth Ave., Fort Lauderdale; 9 p.m.; $45 to $65; 954/462-0222 or www.browardcenter.org

Forget all the Americanized, de-exotified versions of the tango that have turned up on American movies and television shows. Any purist of the sensual dance form knows that true tango comes from Rio de la Plata, the river district connecting Argentina and Uruguay, the twin birthplaces for the dance of lovers. This touring production features talented singers and tango dancers from these very places (and Japan, too), including renowned Rio de la Plata dancer Mora Godoy and Uruguayan singer Alfredo Lerida. Expect a tango showcase by some of its finest progenitors, in a show that addresses the culture surrounding the dance as well as its steps.

Led Zeppelin tribute band at Platforms, 99 S.E. First Ave., Boca Raton; 8 p.m.; free; 561/392-6885.

There are plenty of nightclubs out there playing the same music you hear over and over again on Top 40 radio. For some, the throwback club Platforms will feel like a breath of fresh (if retro) air, taking its inspiration less from Power 96 than from 97.3 The Coast. The dancehall plays music from the ‘70s, ‘80s and ‘90s, with classic rock, disco and new wave music tailored to baby boomers and Gen-Xers. And for the rest of the summer, the venue is hosting live tribute bands of legendary acts. Tonight, dance to Led Zeppelin hits; return for the Eagles next Friday and Billy Joel on Aug. 31.

Opening night of “360” at Cinema Paradiso, 503 S.E. Sixth St., Fort Lauderdale; 8 p.m.; $6 to $10; 954/525-3456 or www.fliff.com

A fine purveyor of social realism and ripped-from-the-headlines narratives, Brazilian director Fernando Meirelles (“City of God”) returns with his latest interconnected mosaic, “360,” which opens exclusively at Fort Lauderdale’s single-screen art-house, Cinema Paradiso. Running through Aug. 23, “360” is bolstered by an all-star cast – Anthony Hopkins, Jude Law, Rachel Weisz and Ben Foster among them – who create a tapestry of romantic life in the 21stcentury. In a story that jumps from Vienna to Paris, London, Bratislava, Rio, Denver and Phoenix, topics such as the international banking crisis, the Arab Spring uprisings and Euro Zone instability are addressed. It sounds like too much for any one director, and one film, to handle, but if anyone should prove up to the challenge it’s Meirelles.


Doug Stanhope at Culture Room, 3045 N. Federal Highway, Fort Lauderdale; 8 p.m.; $20; 954/564-1074 or www.cultureroom.net

If you only know Doug Stanhope from his short-lived tenure as a host on The Man Show, you don’t know the half of one of the funniest standup comedians in the business. Stanhope just isn’t made for television, with its tasteful content restrictions; if Stanhope released a concert film, it would probably be rated NC-17 on language alone. But he’s more than a shock jock – his material is caustic, inspired and relevant to the world we live in and the male psyche. A loud, abrasive provocateur, he’s George Carlin in the body of Andrew Dice Clay, seething with intensity at every live performance, a man coming unhinged at the state of society. Oh, and if you’ve ever heard his material about Dr. Drew Pinksy, you’ll have trouble taking the celebrity doctor seriously ever again.
