  Two events ultimately stalled the Mnemiopsis invasion in the Black Sea. One was the fall of the Soviet Union: in the ensuing chaos, some farmers ceased fertilizing their fields and water quality improved. The other was the accidental introduction of a second exotic jellyfish that happened to have a taste for Mnemiopsis.

  In lieu of dismantling superpowers or importing invasive species, countries have adopted jelly-proofing strategies. South Korea recently released 280,000 native jelly-eating filefish along the coast of Busan. Spain dispatched indigenous loggerhead sea turtles off Cabo de Gata. Japanese fishermen hack at the giant Nomura's with barbed poles. Mediterranean beaches have organized jellyfish hot lines, spotter-boat armadas, and airplane flyovers; the slimy troublemakers are sometimes sucked up by garbage scows, carted off by backhoes, or used for fertilizer. Bathers in the worst areas are advised to wear full-body Lycra "stinger suits" or pantyhose or to smear themselves with petroleum jelly. Most sting-treatment products feature vinegar, the best remedy for jelly venom.

  When, nearly two decades ago, Daniel Pauly, a fisheries biologist at the University of British Columbia, started warning of the dangers of overfishing, he liked to alarm people and say we would end up eating jellyfish. "It's not a metaphor anymore," he says today, pointing out that not only China and Japan but also the U.S. state of Georgia have commercial jellyfish operations, and there's talk of one starting in Newfoundland, among other places. Pauly himself has been known to nibble jellyfish sushi.

  About a dozen jellyfish varieties with firm bells are considered desirable food. Stripped of tentacles and scraped of mucous membranes, jellyfish are typically soaked in brine for several days and then dried. In Japan, they are served in strips with soy sauce and (ironically) vinegar. The Chinese have eaten jellies for a thousand years (jellyfish salad is a wedding banquet favorite). Lately, in an apparent effort to make lemons into lemonade, the Japanese government has encouraged the development of haute jellyfish cuisine—jellyfish caramels, ice cream, and cocktails—and adventuresome European chefs are following suit. Some enthusiasts compare the taste of jellyfish to fresh squid. Pauly says he's reminded of cucumbers. Others think of salty rubber bands.

  The main edible variety in U.S. waters, cannonball jellies, are found on the Atlantic Coast from North Carolina to Florida and in the Gulf of Mexico. They scored quite high on a "hedonic scale" of color and texture in a study led by Auburn University. Another scientific paper hailed jellyfish flesh—which is 95 percent water, a few grams of protein, the barest hint of sugar, and, once dried, only 18 calories per 100-gram serving—as "the ultimate modern diet food."

  The research vessel Point Lobos heaves in the swells of Monterey Bay. After a two-hour ride from shore, the engine idles as a crane lowers the Ventana, an unmanned submarine stocked with a dozen glass collecting jars, into the water. As the submarine begins its descent into the canyon, its cameras feed footage to computer monitors in the boat's dark control room. Widmer and other scientists watch from a semicircle of armchairs. Widmer is allotted only a few trips on the MBARI submarine each year for his research; his eyes are shining with anticipation.

  On the screens we see the bright green surface water darken by degrees to deep purple, then black. White flecks of detritus called marine snow rush past, like a star field in warp speed. The submarine drops 1,000, 1,500, 5,000 feet. We are en route to what Widmer has modestly named the Widmer Site, a jellyfish mecca on the lip of an undersea cliff.

  Our spotlight illuminates a Gonatus squid, which clenches itself into an anxious red fist. Giant gray-green Humboldt squid sail by, like the ghosts of spent torpedoes. Glimmering beings appear. They seem to be constructed of spider webs, fishing line and silk, soap bubbles, glow sticks, strands of Christmas lights, and pearls. Some are siphonophores and gelatinous organisms I've never seen before. Others are tiny jellyfish.

  Every now and then, Widmer squints at an iridescent speck, and—if it isn't too delicate and the gonads look ripe—asks the pilot of the remote-controlled sub to give chase. "I don't know what it is, but it looks promising," he says. We bear down on jellyfish the size of jingle bells and gumdrops, slurping them up with a suction device.

  "Down the tube!" Widmer cries in triumph.

  "In the bucket!" the pilot agrees.

  The whole boat crew pauses to stare at the screen and marvel at a piece of kelp studded with fuzzy pink anemones. We snatch a jelly here, a jelly there, including a mysterious one with a strawberry-colored center, always keeping a sharp eye out for polyps.

  The submersible sails over the wreck of a blue whale, a gigantic rockfish curled up like a cat beside the great skull. We pass a frilly albino sea cucumber and a Budweiser can. We see squat lobsters and spot prawns, bleached sea stars, black owl fish, bouncy coils of eggs, a pale pink orb with tarantula-like legs, lemon-yellow mermaid's purses, English sole, starry flounders, and the purple bullet shapes of sharks. The California sunshine seems dismal in comparison.

  When the submarine surfaces, Widmer quickly packs his tiny captives into chilled Tupperware containers. The strawberry jelly begins to languish almost immediately, as the sunlight disintegrates the red porphyrin pigment in its bell; soon it will be floating upside down. A second unknown specimen with pinwheel-shaped gonads looks perky enough, but we have caught only one, so Widmer will not be able to breed it for public display. He hopes to retrieve more on the next trip.

  He has, however, managed to corral half a dozen Earleria corachloeae, a species he recently discovered. He named it after his two young landlocked nieces in Wichita, Kansas—Cora and Chloe. Widmer produces a YouTube series for them called "Tidepooling With Uncle Chad," which introduces ocean wonders—sea turtle nests, bull kelp trumpets, snail racetracks—he wants them to know.

  Two days later, the E. corachloeae produce a smattering of eggs like grains of fine beach sand. He will dote on his captives until they die or go on display. They are officially "golden children."

  The Killer in the Pool

  FROM Outside

  TO WORK CLOSELY with a killer whale in a marine park requires experience, intuition, athleticism, and a whole lot of dramatic flair. Few people were better at it than top SeaWorld trainer Dawn Brancheau, who, at forty, was blond, vivacious, and literally the poster girl for the marine park in Orlando, Florida, appearing on billboards around the city. She decided she wanted to work with killer whales at the age of nine, during a family trip to SeaWorld, and she loved animals so much that as an adult she used to throw birthday parties for her two chocolate Labs.

  On February 24, 2010, Brancheau was working the "Dine with Shamu" show, featuring SeaWorld's largest killer whale, a six-ton, twenty-two-foot male known as Tili (short for Tilikum). "Dine with Shamu" takes place in a faux-rock-lined, 1.6-million-gallon pool that has an open-air cafe wrapped around one side. The families snacking on the lunch buffet that Wednesday were getting an eyeful. Brancheau bounced around on the deck of the pool, wearing a black-and-white wetsuit that echoed Tilikum's coloration, as she worked him through a few of the many "behaviors" he had learned during his nearly twenty-seven years as a marine-park denizen. The audience chuckled at the sight of one of the ocean's top predators performing like a circus animal.

  The show ended around 1:30 P.M. As the audience started to file out, Brancheau fed Tilikum some herring (he eats up to two hundred pounds a day), doused him a few times with a bucket (killer whales love all sorts of stimulation), and moved over to a shallow ledge built into the side of the pool. There she lay down in a few inches of water, talking to him and stroking him, conducting what's known as a "relationship session." Tilikum floated inert in the pool alongside her, his nose almost touching her shoulder. Brancheau was smiling, her long ponytail flaring out behind her.

  One level down, a group of families gathered before the huge glass windows of the underwater viewing area. A trainer shouted up that they were ready for Tilikum. That was Brancheau's signal to instruct the orca to dive down and
swim directly up to the glass for a custom photo op. It's an awesome sight when six tons of Tili come gliding out of the blue. But that day, instead of waiting for his cue and behaving the way decades of daily training in captivity had conditioned him to, Tilikum did something unexpected. Jan Topoleski, thirty-two, a trainer who was acting as a safety spotter for Brancheau, told investigators that Tilikum took Brancheau's drifting hair into his mouth. Brancheau tried to pull it free, but Tilikum yanked her into the pool. In an instant, a classic tableau of a trainer bonding with a marine mammal became a life-threatening emergency.

  Topoleski hit the pool's siren. A "Signal 500" was broadcast over the SeaWorld radio net, calling for a water rescue at G pool. Staff raced to the scene. "It was scary," a Dutch tourist, Susanne De Wit, thirty-three, told investigators. "He was very wild." SeaWorld staff slapped the water surface, signaling Tilikum to leave her. The whale ignored the command. Trainers hurried to drop a weighted net into the water to try to separate Tilikum from Brancheau or herd him through two adjoining pools and into a small medical pool that had a lifting floor. There he could be raised out of the water and controlled.

  Eyewitness accounts and the sheriff's investigative report make it clear that Brancheau fought hard. She was a strong swimmer, a dedicated workout enthusiast who ran marathons. But she weighed just 123 pounds and was no match for a 12,000-pound killer whale. She managed to break free and swim toward the surface, but Tilikum slammed into her. She tried again. This time he grabbed her. Her water shoes came off and floated to the surface. "He started pushing her with his nose like she was a toy," said Paula Gillespie, one of the visitors at the underwater window. SeaWorld employees urgently ushered guests away. "Will she be okay?" one asked.

  Tilikum kept dragging Brancheau through the water, shaking her violently. Finally—now holding Brancheau by her arm—he was guided onto the medical lift. The floor was quickly raised. Even now, Tilikum refused to give her up. Trainers were forced to pry his jaws open. When they pulled Brancheau free, part of her arm came off in his mouth. Brancheau's colleagues carried her to the pool deck and cut her wetsuit away. She had no heartbeat. The paramedics went to work, attaching a defibrillator, but it was obvious she was gone. A sheet was pulled over her body. Tilikum, who'd been involved in two marine-park deaths in the past, had killed her.

  "Every safety protocol that we have failed," SeaWorld's director of animal training, Kelly Flaherty Clark, told me a month after the incident, her voice still tight with emotion. "That's why we don't have our friend anymore, and that's why we are taking a step back."

  Dawn Brancheau's death was a tragedy for her family and for SeaWorld, which had never lost a trainer before. Letters of sympathy poured in, many with pictures of Brancheau and the grinning kids she'd spent time with after shows. The incident was a shock to Americans accustomed to thinking of Shamu as a lovable national icon, with an extensive line of plush dolls and a relentlessly cheerful Twitter account. The news media went into full frenzy, chasing Brancheau's family and flying helicopters over Shamu Stadium. Congress piled on with a call for hearings on marine mammals at entertainment parks, and the Occupational Safety and Health Administration (OSHA) opened an investigation. It was the most intense national killer whale mania since 1996, when Keiko, the star of Free Willy, was rescued from a shabby marine park in Mexico City in an attempt to return him to the sea. Killer whales have never been known to attack a human in the wild, and everyone wanted to know one thing: Why did Dawn Brancheau die?

  Killer whales have been starring at marine parks since 1965. There are 42 alive in parks around the world today—SeaWorld owns 26 of them—and over the years more than 130 have died in captivity. Until the 1960s, no one really thought about putting a killer whale in an aquarium, much less in a show. The public knew little about them beyond the fact that they sounded dangerous. (Killer whales, or orcas, are the largest members of the dolphin family.) Fishermen tended to blast them with rifle fire if they came near salmon and herring stocks.

  But Ted Griffin helped change all that. A young impresario who owned the Seattle Marine Aquarium, Griffin had long been obsessed with the idea of swimming with a killer whale. In June 1965 he got word of a twenty-two-footer tangled in a fisherman's nets off Namu, British Columbia. Griffin bought the 8,000-pound animal for $8,000. He towed the orca, which he named Namu, 450 miles back to Seattle in a custom-made floating pen. Namu's family pod—twenty to twenty-five orcas—followed most of the way. Griffin was surprised by how gentle and intelligent Namu was. Before long he was riding on the orca's back, and by September tens of thousands of people had come to see the spectacle of the man and his orca buddy. The story of their "friendship" was eventually chronicled in the pages of National Geographic and in the 1966 movie Namu, the Killer Whale. The orca entertainment industry was born.

  Namu was often heard calling to other orcas from his pen in the sea, and he died within a year from an intestinal infection, probably brought on by a nearby sewage outflow. Griffin was devastated. But his partner at the aquarium, Don Goldsberry, was a blunt, hard-driving man who could see that there was still a business in killer whales. He and Griffin had already turned their energies to capturing orcas in the Puget Sound area and selling them to marine parks. Goldsberry first built a harpoon gun, firing it by accident through his garage door and denting his car. Eventually, he and Griffin settled on the technique of locating orca pods from the air, driving them into coves with boats and seal bombs (underwater explosives used by fishermen to keep seals away from their catch), and throwing a wall of net across their escape path. Goldsberry and Griffin would then choose the orcas they wanted and let the remaining ones go. They preferred adolescents, particularly the smaller females, which were easier to handle and transport.

  In October 1965, Goldsberry and Griffin trapped fifteen killer whales in Carr Inlet, near Tacoma. One died during the hunt. Another—a fourteen-foot female that weighed 2,000 pounds—was captured and named Shamu (for She-Namu). In December a fast-growing marine park in San Diego, called SeaWorld, acquired Shamu and flew her to California. Goldsberry says he and Griffin were paid $70,000. It was the start of a billion-dollar franchise.

  Over the next decade, around 300 killer whales were netted off the Pacific Northwest coast, and 51 were sold to marine parks across the globe, in Japan, Australia, the Netherlands, France, and elsewhere. Goldsberry, who became SeaWorld's lead "collector" until he retired in the late 1980s, caught 252 of them, sold 29, and inadvertently killed 9 with his nets. In August 1970, concerned about backlash, Goldsberry weighted some dead orcas down with anchors and dumped them in deep water. When they were dragged up on a Whidbey Island beach by a trawling fisherman, the public started to understand the sometimes brutal reality of the "orca gold rush."

  In 1972 the Marine Mammal Protection Act prohibited the taking of marine mammals in U.S. waters, but SeaWorld continued to receive killer-whale-capture permits under an educational-display exclusion. In March 1976 Goldsberry pushed his luck and the limits of public opinion. He sighted a group of killer whales in the waters just off Olympia, Washington's state capital. In full view of boaters—and just as the state legislature was meeting to consider creating a Puget Sound killer whale sanctuary—he used seal bombs and boats to chase six orcas into his nets at Budd Inlet. Ralph Munro, an aide to Governor Dan Evans, was out on a small sailboat that day and remembers the sight. "It was gruesome as they closed the net. You could hear the whales screaming," Munro recalls. "Goldsberry kept dropping explosives to drive the whales back into the net."

  The state of Washington filed a lawsuit, contending that Goldsberry and SeaWorld had violated permits that required humane capture, and as the heat and publicity built, SeaWorld agreed to release the Budd Inlet killer whales and to stop taking orcas from Washington waters. With the Puget Sound hunting grounds closing, Goldsberry flew around the world looking for other good capture sites. He settled on Iceland, where killer whales were plentiful. By October 1976 SeaWorld's first Icelandic orca
had been captured.

  Over the next few years, Goldsberry spent freely to help create the infrastructure to net and transport whales out of Iceland. In November 1983, in the cold, rough waters off Berufjördur, an Icelander named Helgi Jonasson drew a large purse-seine net around a group of killer whales. Three young animals—two males and a female—were captured and transported to the Hafnarfjördur Marine Zoo, near Reykjavik.

  There they were placed in a concrete holding tank. The smaller male, who was about two years old and just shy of 11.5 feet, would remain there for almost a year, awaiting transfer to a marine park. In the pool he could either cruise slowly in circles or lie still on the surface. He could hear no ocean sounds, only the mechanical rush of filtration. Finally, in late 1984, the young orca was shipped to Sealand of the Pacific, a marine park just outside Victoria, on British Columbia's Vancouver Island. He was given a name to go with his new life: Tilikum, which means "friend" in Chinook.

  Sealand, situated at Oak Bay Marina, was a wholly alien world for a wild orca. Its performance pool—about one hundred feet by fifty feet, and thirty-five feet deep—was created by suspending mesh netting from the floating docks. The pool was open to the marina water, and thus to any bilge oil or sewage pumped into it by boaters. Marina traffic and motors created a cacophony of artificial underwater background noise, obscuring the natural sounds Tilikum had known in the wild. In the fourteen years before his arrival, seven orcas had died under Sealand's care. Their average survival time was just shy of three and a half years.

  At Sealand, Tilikum joined two female killer whales, Haida and Nootka, who were sorting out the social pecking order. (Orca society is dominated by females.) That meant conflict and tooth raking for all three orcas, and even after Haida established herself as dominant, both females continued to push the young Tilikum around. The stress was worse at night. Sealand's owner, a local entrepreneur named Robert Wright, who'd captured his share of Pacific Northwest killer whales in the early 1970s, worried that someone might cut the net to free his orcas or that they might chew through it themselves. So at 5:30 P.M., after the shows were over, the orcas were moved into a small metal-sided pool that was twenty-six feet in diameter and less than twenty feet deep. The trainers referred to it as "the module," and the orcas were left in it for the next fourteen and a half hours.
