Tonight, we embark on a wildlife tour. Well roam with the wolves in the snows of yellowstone; marvel at the diversity of the animal world through the lens of a National Geographic photographer. But we begin with a dive into the lives of some of the oceans most storied and feared predators. The book and movie jaws introduced us to the great white shark more than 40 years ago, and scared us out of our wits. Much of the film was shot in the waters off cape cod, massachusetts. The irony is that when it came out in the mid1970s, there were very few white sharks around cape cod. The species was in the midst of a serious decline, and the movie made it worse, with fishermen hunting the few great whites that there were. White sharks were granted federal protection in 1997, and in the years since, have made a comeback that has delighted conservationists, and frightened swimmers and surfers. On cape cod this past summer, shark sightings and beach closings were about as common as lobster rolls. As we first reported last september, the atlantic great white shark is back. Greg skomal look at this fish. Whitaker look at this fish. Skomal yeah, look at this fish. Whitaker geez. On a tuesday in midseptember, were with dr. Greg skomal, chief shark scientist for the Massachusetts Department of marine fisheries, following an 11foot white shark swimming just feet off the beach near truro on cape cod. Skomal and if youre standing there, you dont know that sharks there. Whitaker you have no idea skomal you dont know that shark is there. Whitaker no idea. Shes like ten feet off shore skomal yeah. Very close now. Whitaker white sharks are so close to shore because thats where their favorite food is grey seals, thousands of which now call cape cod home. Skomal this is the restaurant right here. These sharks have found the restaurant, and theyre waiting for the doors to open. You know . And when those seals begin to leave the beach. You know. Whitaker its dinnertime. Skomal its dinnertime. Whitaker skomal and his team from the Atlantic White shark conservancy are trying to attach electronic tracking tags to as many sharks as they can 230 so far. The way they do it is fascinating. Pilot wayne davis locates sharks from his spotter plane, then guides boat captain john king onto them. Wayne davis use a little gas, john. Hes right on the shoal. Its about as good as its going to get. Whitaker standing on a pulpit on the bow of a small boat, greg skomal wields a long pole that has a dart and a tag at the end. Skomal right, right there. Done. Whitaker you got him . Skomal tagged. Whitaker that was it megan winton beautiful, all right. John king my god. Beautiful, beautiful placement, greg. Skomal thank you, john. Nice work. Whitaker you can see, you can see where it was . Skomal yeah, you can see it right at the base of the dorsal. See it . Whitaker yeah, yeah, yeah, yeah. Skomal now were going to learn about that fish for the next nine, ten years. Whitaker they will track the fish because the tag constantly emits a ping that is picked up when the shark swims close to acoustic receivers attached to buoys. And how many of these do you have uovermassacses. Whitaker andt skomal thats just us, yeah. And so we can actually track the movements of our white sharks when they leave here. Whitaker the tags also help skomal, and his research colleague megan winton, figure out just how many sharks there are, and have established that cape cod is now one of the worlds white shark hot spots. They regularly haul buoys out of the water and Download Data from them to a tablet that displays each time a tagged shark swims by. Winton lots of white shark detections. Whitaker this tells them a lot about individuals. They have confirmed that theyre loners, and that the same one will often come back to precisely the same hunting ground, year after year. A white shark seemed to be hunting greg skomal in 2018 when it came up, jaws open, right under the pulpit. King oh holy crap skomal it came right up and opened its mouth right at my feet whitaker that shook him up for a bit. But he insists it shouldnt shake up the public. Skomal all i can tell them is, is that the probability of them being bitten is incredibly low. But theres not much more i can say. Whitaker because that fear is primal. Skomal i think that fear is primal. I think its innate. I think its in them, its in us, its in all of us. Whitaker five days after our day on the water off cape cod, we needed a bigger boat, for a very different sharktagging expedition 600 miles to the northeast, just off hay island in nova scotia. Chris fischer morning. Whitaker morning, how are you . We boarded a 125foot Research Ship called ocearch, which has been tagging Atlantic White sharks from florida to canada since 2012. Founder Chris Fischer invited us to join the first day of his 2019 nova scotia expedition. Fischer and we come up here. Weve been here 24 hours. Weve seen two or three sharks, and no one ever even knew to come look here before. Whitaker ocearch launches a team on a small boat to hook white sharks, much as fishermen would, using long lines, bait and floats to keep them near the surface. Fischer hooked in the corner of the mouth. Squared away. Everythings green out here. Whitaker ocearch is a converted alaskan crab boat equipped with a platform thats lowered into the water off one side. As the small boat tows the shark alongside, ocearch fishing master Brett Mcbride leaps onto the submerged platform, into water thats 49 degrees. With the line in his hand, he guides an 1,100pound male white shark onto the platform is raised out of beaching the shark. It offers no resistance, worn out after being hooked and towed for nearly an hour. Mcbride gets right in its face to insert a hose between its giant jaws. Brett mcbride im keeping clean seawater flowing over its gills. Im making sure its getting good oxygen. Whitaker a team member starts a clock. They dont want to keep the shark out of the water for more than 15 minutes. And ocearch chief scientist dr. Robert heuter gives me an opportunity im not quite sure i want. Robert hueter so bill, just go ahead, go ahead. And take your time. Just feel how beautiful that is. Whitaker oh my god. Hueter how smooth. And then go this way. Rub your hand the other way and you feel its kind of bumpy. Whitaker my god. The ocearch team swarms the shark, drawing blood and tissue samples, picking off parasitesag its girth and length. Christian purcell 371 total whitaker thats 371 centimeters, or 12 feet, two inches. The biggest atlantic great white theyve caught was a 16foot female who weighed 3,500 pounds. As Chris Fischer measures this one, bob hueter inserts an acoustic tag, like the one greg skomal attaches with a dart. That doesnt harm the shark . Hueter no, its just, it floats in the body cavity. Fischer lets roll the shark. Everybody step back. Whitaker after the shark is rolled onto its belly. There we are Christina Lobuglio were at 11 minutes whitaker . Chris fischer drills through the dorsal fin. He insists its no more painful than piercing an ear. Hes attaching the tag that really sets ocearch apart in the world of white shark tracking. Fischer this spot tag allows us to track this animal in real time for up to five years. Whitaker the spot tag will send a signal to a satellite each time this sharks dorsal fin comes above the surface of the water. Ocearch has put more than 50 of them on Atlantic White sharks, and displays their tracks on its website. Fischer and thats how you learn not only where they are, but what theyre doing, where they are, which is what you need to know to manage. Right . Wheres the mating . Wheres the birthing . Wheres the foraging . Wheres the gestating . Whitaker while some scientists criticize the ocearch techniques as too invasive, they are gathering a lot of data. 17 Different Research projects will get samples and information from a single shark. Doesnt take much to make everybody happy. Whitaker still, there are a lot of unknowns. No white shark has ever been kept in captivity, and no one has ever seen them mate or give birth anywhere. But there are also discoveries. The ocearch team has confirmed that the waters off long island are an important nursery for baby whites like these, called pups. Did you get him . Skomal yep, got him. Whitaker and back on cape cod, acoustic tags are teaching greg skomal about just how far adult sharks travel. Whats the most interesting thing youve learned about them . Skomal we now know, based on the tagging work weve done the last ten years, is that, when they leave cape cod, they go down to florida, and they spend the time in the gulf of mexico. And they overwinter in these southern climates. But since some of these sharks move out into the open atlantic ocean, and when theyre out in the middle of the atlantic, they dive down at depths as great as 3,000 feet every day. And theres not a scientist on earth that can tell you why they do that. Whitaker scientists have learned how longlived they are. Komal hite sharks, we now know, live over 70 years. Whitaker 70 years . Skomal 70 years. Ker they dt hunting seals until their late teens, but when they do, watch out. In this footage egmal shot, you see a seal leap out of the water with a shark right on its tail. Skomal have you ever seen that before . Whitaker here, the shark catches a seal, and the ocean water explodes in blood red in an instant. The shark then swims away, with half a seal in its jaws. Seals have been protected by federal law since 1972, and some 25,000 now live near cape cod. More seals means more sharks, and thats what worries the swimmers and surfers sharing the water with them. This photo was taken at the cape in september 2019. Great white sharks very rarely attack people. The one that killed a swimmer named Arthur Medici just off this beach last september was the first fatal attack on cape cod since 1936. But it triggered a fear of attacks that can hardly be measured. Scary warning signs on every beach. Stopbleed kits at lifeguard stands. A phone app called sharktivity that reports sightings in real time, with local news doing much the same, and Community Meetings packed with frightened citizens. Woman no sharks or seals are worth a young mans life. Theyre just not. applause whitaker youre the scientist, but you also live here, and, you know, people are afraid. Skomal we cant bury our heads in the sand when it comes to shark attacks. And so, thats in my face every day now. And then it always falls back on the you know, the question of, well, what do you tell your kids to do . You know . Whitaker what do you tell your kids to do . Skomal you know, i i tell my kids, dont go out past waistdeep. Whitaker thats chilling advice, for swimmers, for surfers, and for the Cape Cod Chamber of commerce. Fischer i mean, weve basically got to undo everything jaws did. I mean, weve got half the people on the eastern seaboard terrified about something that almost never happens. Whitaker i saw the teeth on this character here. People who are swimming nearby should not be afraid of that . Fischer no. Theyre clever. Like, even though we dress up like their food and try to fool them, they very rarely get fooled. Whitaker what do you mean . What do you mean, dress up like their food . Fischer you ever seen what someone in a wetsuit looks like, compared to a seal . Whitaker hes got a point. When this white sharks 15 minutes on the ocearch platform ran out, we were ordered off. That was amazing they gave him a name. Fischer sydney whitaker . For the nearest nova scotia town, and began lowering him back into the water. And what you guys have done to him this does not harm or hurt the shark at all . Hueter no, because were were monitoring the stress of the animal throughout. Whitaker after a couple of minutes, h especially when he noticed the ocearch photographer in the water around the corner. Oh,e he sees you, rob whitaker finally, with fish master Brett Mcbride helping steer him by the tail, off went sydney. There he goes. Do your thing. Good luck, old boy. Sydney. Yeah. applause whitaker sydney has been busy in the months since we met him in nova scotia. He migrated as far south as florida, and as of early january his spot tag showed him off the North Carolina coast. ticking how to be shark smart at the shore. At 60minutesovertime. Com.

The story of the big bad wolf may be the most memorable and frightening of all the fairy tales told by the brothers grimm. That grim reputation actually produced a very real result in america in the early 20th century. Wolves were wiped off the landscape trapped, poisoned, and hunted until there was not a single one left in the american west. The National Park service brought wolves back to Yellowstone Park almost exactly 25 years ago, following a bitter debate between wildlife groups, who wanted them restored, and ranchers, who most definitely didnt. Even today, the wolves of yellowstone stir strong emotions. But, as we first reported in 2018, theyve also had an impact that almost no one saw coming. In the dead of winter, Yellowstone Park is a beautiful but forbidding place. Howling wind, subzero temperatures, six feet of snow. Just finding enough food to survive is a profound struggle for every animal. Waterfowl, bison, elk, foxes, they all have to work for every morsel. Yellowstone was the worlds first National Park, founded in 1872. And
