Meet the Biologists Who Rescue Whales Trapped in Fishing Gear

Scott Landry and his team had been searching the waters of Cape Cod Bay for hours without any luck. For several days in September, mariners had reported to the Center for Coastal Studies in Provincetown, Massachusetts, that they'd seen a humpback whale trailing ropes and buoys from its enormous body. Landry, the center's director for marine animal entanglement response, knew time was growing short: Every day a whale spends entangled costs it precious energy and increases its chances of dying.

The crew had checked every reported location and was growing concerned about the fading daylight when a whale-watching boat called to say it had spotted the animal more than 20 miles away.

The five-member team sped out of the bay on their 35-foot, 600-horsepower rigid inflatable boat toward the animal's last known location. Finally spotting it, they worked to get close enough for a clear look at how the ropes and buoys were wrapped around the whale's body.

It wasn't easy. The boat bounced in the wind and rough seas. The whale moved quickly and obscurely, diving for up to seven minutes at a time. No one knew what direction the animal was moving or where it would surface. When it did come up for air, it disappeared again almost immediately. "We need a clear idea of how a whale is entangled to disentangle it properly,” Landry tells Mental Floss. “We had about two seconds when it came up for a breath."

When he finally got a look, the news wasn't good. "It was the worst kind of entanglement—a rope wrapped around its upper jaw," Landry recalls. Because a whale's head is seldom above the surface and ropes there may not trail as far, they prove hardest to remove. "The whale was moving at high speed, we were moving at high speed, and we had to pace alongside it and get within 30 feet to cut it free. The window of time and the target were both small."

This time of year, many humpback whales travel from feeding grounds off the coast of Canada and New England to winter calving grounds in waters around Florida and the Caribbean, a journey of more than 1000 miles. A surprising number of them are dragging materials along with them—rope, nets, and other gear in which they've become hopelessly entangled. Increased fishing in areas where whales forage has resulted in more entanglements, which can kill them.

Humpback whales reach weights of 80,000 pounds and lengths up to 60 feet. You need a good reason to approach one of these massive creatures in a small craft on the open ocean. The special teams that free the whales believe it's worth risking their lives to save these endangered cetaceans.

These teams exist all over the world. Landry's institute, the Center for Coastal Studies, has freed more than 200 large whales and other marine animals since 1984. It belongs to the Atlantic Large Whale Disentanglement Network, which includes National Oceanic and Atmospheric Administration (NOAA) fisheries offices, state offices, and research institutions from Florida to Canada.

The U.S. had 123 confirmed entangled whale cases in 2016 alone, but the ones we see likely represent only a fraction of the total. Jamison Smith, disentanglement coordinator for NOAA, tells Mental Floss that lack of centralized record-keeping early on means no one knows the actual number, but since the early 1980s, it has hit at least the low thousands. At least 83 percent of North Atlantic right whales became entangled at least once between 1980 and 2009, and more than half of the humpback whales in the Gulf of Maine have had at least one entanglement.

"Right whales and humpbacks have a huge problem," Michael Moore, senior scientist at Woods Hole Oceanographic Institution (WHOI), tells Mental Floss. "Something radical has to happen, or these species are going to go away."

A WORLDWIDE—AND DEADLY—PROBLEM

Marine animals get caught up in just about anything humans put in the water, and we put in a lot of stuff—commercial fishing gear, recreational fishing gear, buoy warning systems, trash. "This problem plagues whales throughout the world," Amy Knowlton, research scientist at the New England Aquarium's Anderson Cabot Center for Ocean Life, tells Mental Floss. "It is one of the biggest conservation issues for marine mammals."

Whales off U.S. coasts most often get tangled in active fishing gear. On the East Coast, it's mostly snow crab and lobster gear. At the height of lobster season, close to a million vertical lines lurk in waters off Maine, and North Atlantic right whales, which are facing extinction in part due to entanglements, may encounter these lines about 2500 times a year. These plankton-grazing whales, which can reach 55 feet long and weigh 128,000 pounds, move slowly through the ocean with open mouths, so most entanglements start there, Knowlton explains. Once ensnared, the whales tend to thrash and roll, which only makes the problem worse, wrapping the ropes through their baleen and around their heads and flippers.

On the West Coast, where NOAA had 71 reports of whale entanglements in 2016, the vast majority in the past two years involved Dungeness crab fishing gear, located along the entire coast. Last year, for example, that gear was responsible for 22 out of 29 entanglements that NOAA definitively associated with specific fisheries or gear types.

Ghost nets—abandoned fishing gear drifting in the ocean—also entangle whales, as does other debris. Junk tends to be more prevalent in certain parts of the ocean, accumulating in gyres and along currents. More debris equals more entanglements.

In a 2012 paper in Conservation Biology, WHOI researcher Julie van der Hoop reported that scientists determined cause of death for 43 percent of 1762 known whale mortalities in the Northwest Atlantic between 1970 and 2009. Of those, 67 percent resulted from human interactions, and entanglement in fishing gear was the primary cause of death.

Entanglement can cause whales to drown or seriously injure and eventually kill them. If they survive, the gear can easily double the drag an animal experiences as it moves through the water. "They can't feed, and they exert a lot more energy just to swim, dragging that gear," Knowlton says. "Their health declines and, if they don't drown at the outset, they experience a slow, painful death."

Expending that extra energy can mean the difference between a female successfully reproducing or not, according to Moore, and with so few right whales remaining, reproduction is critical to survival of the species.

"The calving rate in North Atlantic right whales has been sparse, driven to some degree by lack of food but also wasteful pursuits such as swimming through the water pulling a whole bunch of excess drag," Moore says.

Even whales that free themselves or are freed by humans experience stress, pain, and loss of energy.

THIS IS HOW YOU FREE A WHALE

In order to disentangle a whale, you first have to find it. "When you consider the size of the ocean, the odds of that happening are incredibly small," Landry says. In some areas, most reports come from commercial fishing operations. The research community and the public also report whales in need of help.

Once a team reaches the whale, they have to assess the situation before taking any action. "You might think we just get in there and start cutting stuff off the whale," he continues. "But we found through trial and error that doesn't help. You have to understand how the whale is entangled and strategically cut things away. Every situation, every whale differs. Sea conditions differ. No two disentanglements are alike."

Often, the first step is for a crew member to use grappling hooks to attach buoys to the animal to help them track it and slow it down. This tactic is one of many they use that was inspired by historic whaling techniques, Smith says, but there's a key difference: "They were trying to kill the whale and we're trying to save it, which is harder to do."

Meanwhile, another crew member with a camera on a long pole assesses the situation. The team then determines the best approach and attempts to cut the whale free using specially designed knives on long poles.

"You're running on adrenaline, focused on the animal and the gear and how to best access that in a safe manner," Knowlton says. "I've spent a lot of time with right whales, and feel I have a sense of what to expect, but they always throw surprises at you. It is not a comfortable situation to be in. I really wish nobody had to be in it."

Keeping crews safe remains priority one. Whales are large, powerful animals. Entanglement creates stress and—despite a popular misconception that whales understand our motives—they have no idea we are trying to help them, Landry says. "Their response is a fear response. Most deal with it by trying to flee, but others will try to defend themselves."

Even so, only one person has died while disentangling a whale under current protocols. Joe Howlett, a long-time member of the Campobello Whale Rescue Team in Canada, was killed July 10, 2017, off New Brunswick by a just-freed right whale, which may have breached or flipped.

Network members plan a response based on the animal's distance from shore, weather, time of day, and availability of resources such as boats and crew. "The biggest challenge is trying to keep a consistent crew on call day in and day out, year after year," Landry says.

The success rate varies. "If we can get our hands on the whale, figuratively, we have about an 85 percent chance of disentangling a humpback," Landry says. "A 50 to 60 percent chance on a right whale."

Knowlton points out that 25 percent of all entangled animals reported just disappear: "A lot more we see multiple times, but weather and other challenges mean we can't get out there. In short, disentanglement is not the solution."

Eliminating whale entanglement entirely would require keeping all rope and debris out of the ocean—not a likely scenario. But lawmakers and scientists are working on solutions. Seasonal restrictions on fishing and modification of gear could help.

Rope strength plays a role, according to Knowlton. Strength of ropes used by commercial fishing has increased, and with it, the severity of whale injuries. Using rope that breaks at 1700 pounds—more than strong enough for the majority of fishing needs but something a whale likely could break—could reduce probability of mortality by 72 percent.

Developing gear that doesn't use ropes could make an even bigger difference. This has been done in parts of the world, and oceanographic researchers routinely retrieve gear using GPS and tracking technology and not ropes. "With economies of scale, that could be conceivable for fisheries," Moore says. "The argument that you need a plastic float on the surface to know where a trap is set is a little antiquated given the technology we have now." Ropeless methods could even help fishermen, because they lose gear to whale entanglements.

As for the whale Landry's team pursued in September, after an hour of near misses, the team was able to finally get close enough to cut the rope free with a hook-shaped knife on the end of a 30-foot pole. As they always do, they removed the rope and buoys from the water. (The National Marine Fisheries Service archives all removed gear for continued study, with the ultimate aim of better understanding and, ultimately, preventing entanglement.)

Had the tourist boat not happened upon the whale, it almost certainly would have died.

"That's one of our biggest fears," Landry says. "It was just a tiny chance for someone to see that whale before it left the area entirely and went somewhere we would never find it." It's happened before, he notes. "You win some and lose some. It's a big responsibility. On the bright side, more often than not, we're able to get the job done."

Pretty in Pink: Drone Captures Birds-Eye View of Massive Flamingo Flock in Kazakhstan

Flamingos sport some of the most eye-catching plumage in the animal kingdom. Their diet of beta-carotene-rich plankton and crustaceans produces a distinctive pink hue that's hard to miss. One flamingo is striking on its own, but the birds are even more impressive as a crowd, as demonstrated by the footage below.

As Fox 13 Tampa Bay reports, Azamat Sarsenbayev used a drone to capture this video of flamingos congregating on Lake Karakol near Aktau, Kazakhstan. A flamingo flock (also called a flamboyance) can contain up to several hundred birds. Flamingos do a lot together, including mating displays. From above, everyday life for a flamingo makes for a breathtaking, candy-colored spectacle.

This footage was taken during the species' migration south. By the end of their journey, the birds will likely be settled in the Khazar nature reserve or even farther south in Iran. After checking out the video, read up on these fascinating facts about flamingos.
