good evening. thank you for joining us. it's one of our primal fears of summer. predators in ocean waters, invisible until they attack. we're talking about sharks. many contend their reputation is

unfairly sinister. last year saw a record high number of shark attacks. abc's david wright is off the coast new england tagging and tracking the great white, while a young man attacked a year ago decides it's safe to go back in the water. >> reporter: just when you thought it was safe to go back into the water, a powerful reminder why you might just think twice. "shark week" kicked off sunday night on discovery at a time when shark attacks have been on the rise worldwide. 98 attacks last year, a record number, more than half of them here in the u.s. already this year 32 attacks have been reported around the globe. including one this past weekend when an 11-year-old boy was bitten while surfing in north carolina. >> i was crying. i was scared. i didn't know what happened. >> reporter: as millions head to the beaches this summer -- we set off from cape cod looking for great whites.

>> should be a light breeze. >> reporter: our guide, one of the world's foremost experts, marine biologist dr. greg skomel. >> when you look at a shark, what do you see? >> i see a perfect fish, if you will. >> reporter: he's been studying sharks off the new england coast for more than three decades. some of his friends call him hooper after the richard dreyfuss character from "jaws." >> it's a bull shark. he scaped me when i was taking samples. >> reporter: do you have scars? >> i was cutting the jaw of a shark and my knife slipped and i drove it into my leg. >> reporter: in his work for the state of massachusetts and the white shark conservancy he gets up close and personal with plenty of sharks. here's one he filmed last week. the first shark of the season chomping on a seal. >> it was really quite spectacular. there's lots of seals here, there's lots of sharks here. we really don't get to see them feed on seals that often. >> reporter: every summer he spends at least two days a week

tagging great whites. looks like a harpoon. >> it does. it actually is a harpoon that we've modified. this is the tag right there. so we'll pull that magnet off which will turn it on. and then that will ping away for ten years. >> reporter: those pings detected by audio buoys positioned along the shore. every time a shark swims up too close. >> a couple little guys, huh? >> that's right. >> he and fellow researchers check them regularly. >> he was here on the 20th. >> reporter: as part of a five-year research project to see who's lurking offshore. >> scratchy, huh? >> scratch and sniff. >> reporter: scratchy is one of the sharks they tagged last year. the researchers give them all colorful nicknames. >> we've got salty, we've got chex, marianne, the skipper too. >> what we have here -- >> reporter: each one of those red marks represents a shark sighting. 300 to 400, most of them within one-quarter mile of beaches

packed with summer tourists. >> we're out here about now here, we refer to it as the colosseum. where the seals go to die. >> reporter: where the seals hang out. that's what's attracting the sharks. in the surf they look an awful lot like human swimmers. up overhead -- >> that's our spotter pilot. >> reporter: our eye in the sky, a spotter plane casts a birdseye view watching for what they call a predation. basically a shark enjoying some lunch. >> knowing what you do about sharks, do you ever think twice about going into the water? >> i do, actually. if i'm on the eastern shore of cape cod and i'm in an area where there's high densities of seals, i am going to think twice. >> reporter: he's a "shark week" regular. his film "jaws of the deep" -- >> pretty cool. >> greg, we're seeing from it the aerial, that's amazing. >> oh, wow. >> reporter: he and colleagues travel to guadalupe, mexico,

shark cage to test whether magnets repel sharks is dick elder, australian navy diver who lost an arm and a leg to a bull shark in 2009. did it take some convincing on his part? >> not really. >> no? >> not even a little bit. >> this area looks a little more substantial under water. still we don't know if it's going to stop a shark going through it. >> it doesn't look shark-proof in any way. >> big box coming in, big box coming in. >> two sharks, no, three sharks. >> yeah, this is awesome! >> here comes another one. >> wow, that is incredible! >> reporter: both men now fight to protect the very creature that tried to eat them. >> are you believers now? >> yeah. >> yeah, i think so. >> sharks, popular culture has told us they're bad, let them die. it doesn't make sense, that's like saying i don't like pandas,

let's kill all the pan daz. >> it's more like, you've been in a car crash and you're out there advocating for higher speed limits. right? >> would you get in a car crash and advocate nobody should drive? right? >> reporter: hollywood may overstate the threat just a bit. the fear factor part of what people have loved ever since "jaws." >> we have to realize that everything that happened in that film was ridiculous. we have to keep that in context. >> hang on tight. >> reporter: moments later, on our boat, we got our first real glimpse at a great white. >> there's blood in the water a few miles away. a shark with a seal. it's a bumpy ride. >> reporter: the spotter plane circles above the spot where we're headed. >> the buoy, halfway between the buoy and the beach -- >> i see it, yeah. >> over this way. >> splash in the water right over here. there's the shark eating the seal!

>> not too close, john. shark's right there. >> reporter: right about now i know just how chief brody felt in "jaws." >> we're going to need a bigger boat. >> i've never seen a fish so big. that is astonishing. >> look at that. >> here, sharky shark. >> reporter: a go pro gives us a close-up view. he's a 12-footer, 1,500 pounds. >> we're fingerprinting it. oh, oh! wow. yeah. let's get the tagging pole. >> reporter: just as he's getting ready to tag it, the shark dives, slipping away into the deep. >> aside from the obvious, is there any way to bring him up? >> take off your shoes? >> reporter: no, thank you. i'll leave that to the experts. >> starting to come up, hold on. >> i see him now. >> i'm ready.

tag, tag, tag! >> wow. you have the touch. >> reporter: and thanks to that acoustic tag, they'll be able to keep close tabs on him from now on. >> that's a pretty good white shark. you don't see that every day. >> reporter: i'm david wright for "nightline" in cape cod. >> there's more where that came from, as "shark week" airs all this week on discovery. up next, "top gun" star kelly mcgillis attacked in her home. kanye west's shocking new video "famous." what was he thinking? anyone with type 2 diabetes knows how it feels to see your numbers go up, despite your best efforts. but what if you could turn things around? what if you could... love your numbers? discover once-daily invokana®. it's the #1 prescribed sglt2 inhibitor that works to lower a1c.
