TEMPE, Ariz. -- It's a big week for shark lovers! The 27th annual Shark Week has begun on the Discovery Channel, and fans are sinking their teeth into anything and everything shark-related.

To help celebrate the event, we sent Ryan O'Donnell into the shark tank at Sea Life Arizona at Arizona Mills Mall. Sea Life is hosting numerous shark-related activities for kids all week long.

Sea Life's Malori Heppler filled us in on different types of sharks. She says not all sharks are dangerous. "This is going to be a reef shark," says Heppler. "This is going to be the kind of shark  the you're going to see here at the aquarium."

Of course the Great White sharks are among the most threatening. But your chances of being attacked by a shark in the ocean are slim. "You're more likely to be struck by lightning that to be attacked by a shark," she says.

On Tuesday's Good Morning Arizona, Ryan donned a wet suit and braved the shark-infested waters of the tank at Sea Life Arizona. He brought a camera into the tank for an up-close look.

"People's fascination with sharks is that they are one of the ocean's top predators," says Sea Life's Matt Minkalis. "They're so advanced when it comes to hunting their prey."

Here are some of the activities planned at Sea Life Arizona for this week:
-Shark Bingo with the different species of sharks that live inside the aquarium
-"Fin-tastic" facts throughout the aquarium, and up-close views of shark artifacts
-Opportunity to make a shark puppet to take home
-Guests will receive 15 percent off all shark plush in the retail shop

Guests that wear a fin (or shark image) to Sea Life this week will receive $5 off a regular priced admission. This is valid only for the guest wearing the shark. Discount cannot be combined with any other offers or applied to pre-purchased tickets.

Guests can also get free admission to Sea Life by helping by donating at the blood drive, Wednesday August 13, from 10:00 am-3:00 pm, in partnership with the American Red Cross.
