In order to sustain their electron flow, all organisms need electron donors and electron acceptors—for most animals, this means receiving electrons from the glucose in food and passing them to the oxygen we inhale. Chad King: Whale falls are very rare, relatively, and the chance encounter like this was really important for science. Follow us on social media to add even more wonder to your day. The bodies of whales, turtles and other sea creatures have washed up on Mauritius shores, five weeks after the MV Wakashio ship ran aground off its coast. Such places support unique biomes where many new microbes and other lifeforms have been discovered. Narrator: This is a dead whale, which scientists recently discovered at the bottom of the Pacific Ocean covered in all kinds of creatures from bone-eating worms to deep-sea octopuses. They have their pods but that’s just an artificial assemblage of their collection. But by the time phytoplankton reach the ocean floor, they retain very little in the way of organic carbon, having been picked over by other creatures living in the sea. Could cosmic events be leading sperm whales to their deaths? So when they fall to the bottom, they can sustain entire ecosystems … for years. Like Atlas Obscura and get our latest and greatest stories in your Facebook feed. See. An 8-minute video as featured in the Blue Planet documentary explains what happens to a whales carcass in the ocean. But the ocean is expansive; the odds of finding a whale fall are slim, so when scientists get the chance to create one for themselves, it’s not something to pass up. But little, if any, sunlight penetrates the ocean with enough intensity to reach many of these sunken whale graves—without light, no carbon-containing organic molecules can be produced via photosynthesis. Vertebrae from a whale, shown about seven months after its carcass was placed at the bottom of the Pacific Ocean. Thousands of YouTube users have been surprised with a viral video, which shows the precise moment in which scientists find at the bottom of the sea the body of a huge whale , which was devoured by hundreds of creatures . Divine providence usually comes in the form of dead phytoplankton: microscopic, photosynthetic organisms that live near the ocean surface and sink to the bottom when they die (a phenomenon known as “marine snow”). The research crew has come to study this “whale fall,” the term given to the sumptuous feast left behind when a whale dies and sinks to the seafloor. And like the epicenter of an earthquake, the magnitude of CostcOasis’s impact would radially decrease—there would be a flurry of activity inside the warehouse, less activity within a one mile radius, and less activity still within a 10-mile radius. And by the time they arrived, it was overrun with octopuses. However, what came as a surprise to ocean researchers was the finding that dead whales support entire ecosystems. Chad King [Research Specialist at Monterey Bay National Marine Sanctuary]: We saw one or two in particular grab onto flesh and do what we were calling an alligator roll — spinning around to twist off pieces of flesh. Populations would explode, and people would flock to the new metropolitan scene: call it CostcOasis. Although efforts are often made to save them, without water to maintain their buoyancy, the weight of the whale's own body soon begins to crush the internal organs. As you would guess, other fish and sea animals initially eat the meat off the carcass. "So these are worms that have symbiotic associations with bacteria. Usually the animal is turned over to a rendering company. After he was laid to rest, Patrick was revisited by the MBARI team every few months, and an intensive longitudinal study of his corpse (along with the other sunken whales at disparate depths) followed this process. While skeletons are generally associated with death, decay, and lifelessness, they are positive omens on the ocean floor. The bacterial communities that exist on whale falls can survive for up to 100 years (maybe even longer); for this duration, life will flourish. When the scientists returned to the site, they found their transponder gone and their whale nowhere in sight. "Yes!" They likely use the suckers on their tentacles to pick up their prey and then carefully transfer them from sucker to sucker into their mouths. Unfortunately, the makeshift anchor was not heavy enough to overcome the buoyancy of the entrapped gases. All you need is a dead whale, patience, and maybe some extra train wheels. At least, that’s what the conventional wisdom said. "We are so excited up here. It's likely that the real number of dead whales is much higher, as current estimates indicate that just about 1 out of every 10 dead whales wash up on the shore (the remaining sink to the bottom of the seafloor). In 2011, a 20-meter-long fin whale washed up on a beach near San Diego, California. Offer subject to change without notice. By Alex Fox Feb. 26, 2019 , 12:55 PM. Instead, they have these rootlets that burrow into the bone and then the bacteria are able to metabolize the fats and oils that are in the bone themselves.". It's not even digested all the way.". Photosynthetic organisms (like plants) take in sunlight, and most animals get their energy secondhand by eating plants (or by eating animals that eat plants). MBARI researchers have sunk five whales in the last 15 years, at different depths. Once the body comes to rest, biologists refer to this as a whale fall. * So past a certain depth, there should be no life. Among the creatures seen in … without light, no carbon-containing organic molecules can be produced via photosynthesis. And that's why there aren't many critters crawling or swimming at the bottom. While the dead whale is clearly what the creatures on the bottom of the sea are most interested, at least one has also found the remote operated vehicle of interest. Octopuses, deep-sea fish, crabs … The MBARI group went back to shore to gather more weight, attaching a GPS transponder to the whale so they could find it again. This particular whale, affectionately (and posthumously) named “Patrick,” unwittingly donated his body to science; you might say that Patrick became food for thought. Perfect conditions for a sunset sailing cruise, or maybe a kayaking trip. You'll also notice some eel-like creatures swimming around. They’re all in various stages of disappearing. Above water, the majority of energy for all living things is created in the form of carbon, through the process of photosynthesis. Winner will be selected at random on 01/01/2021. Account active “And everybody looks around; okay, well now what?”. When a whale is laid to rest in such a nutrition-starved community, it disrupts the natural order, serving as a bountiful buffet for many sea dwellers. Narrator: For example, it will help researchers better understand these elusive, deep-sea animals like those bone-eating worms, which is one reason why they were so excited. Narrator: In other words, they basically outsource digestion! A leading-edge research firm focused on digital transformation. Eventually, the skeleton will be buried under sediment, and the microscopic bacteria that spend their lives eking out a famished living in the dark will flourish. When this happen, the dead whale will eventually become food to the other animals below. But the natural world always returns to its natural state. A whale that beached itself and died or died then became beached---doesn’t matter, it’s dead. Narrator:  The bottom of the ocean is a desolate place. Deep-sea animals must survive on the decaying scraps of dead organisms from the upper layers of the ocean, which sink to the bottom. With all of the food eaten, human populations would either migrate away, or dwindle back to their initial, small numbers. Narrator:  That's one of the 31 scientists aboard the Exploration Vessel (E/V) Nautilus.

This first happens at the epicenter, and gradually the surrounding communities, the whale fall suburbs, follow suit. To overcome this obstacle, they have adapted ways to use materials like methane gas and manganese rock as their electron acceptors. A deal had been struck between The Coast Guard/Department of Fish and Wildlife and the MBARI researchers: if they could seize a dead whale before it drifted too close to shore (removing a beached whale is, apparently, very difficult), then the researchers were free to use it for their own purposes. Researchers aboard a deep-sea exploration vessel called E/V Nautilus discovered a whale carcass off the coast of California, more than 3,000 meters down. Follow us on Twitter to get the latest on the world's hidden wonders. Like a rainy season precipitates a robust harvest, a whale fall means good eating for the extremophiles that live in seafloor sediment—it’s nothing short of a miracle. Atlas Obscura and our trusted partners use technology such as cookies on our website to personalise ads, support social media features, and analyse our traffic. Marine biologists are engineering creative new ways to ride along with whales, bob with jellies, and drift with plankton. Chad King: He was a little lethargic and maybe not going to be able to swim away too fast. The scene was absurd. Bay Curious is a podcast that answers your questions about the Bay Area. What happens to a dead whales carcass at the bottom of the ocean? Whale fall samples help us learn more about these strange processes. When whales die in the ocean, their bodies eventually sink to the bottom. Luckily, they stumbled upon it six months later—by happenstance. Subscriber In the fall of 2019, the crew came across this baleen whale more than 3,000 meters down. As it turns out, they're not actually eels, but likely long-bodied fish known as eelpouts, which have a taste for decaying whale blubber. A whale fall occurs when the carcass of a whale has fallen onto the ocean floor at a depth greater than 1,000 m (3,300 ft), in the bathyal or abyssal zones. This is the moment scientists discovered a fallen whale carcass being devoured by marine scavengers at the bottom of the Pacific Ocean. That the whales are in their family. FULL STORY Tiny 'bone-devouring worms', known to both eat and inhabit dead whale skeletons and other bones on the sea floor, have a unique ability to … Consider supporting our work by becoming a member for as little as $5 a month. They take the dead animal to a facility that cuts it up, grinds it, burns it or otherwise disposes of the carcass. By this time, the bones were … Despite the dearth of carbon in these extreme environments, it is still generally the preferred food of extremophiles; hoping for a nutritious meal, these bacteria seek salvation from on high. To plant a whale carcass on the bottom of the ocean, creating what microbiologists call a “whale fall.”. However management decides they should mix them–whichever ones happen to be born or bought or brought in–that’s not a family.” SeaWorld began the park in 1964 at San Diego SeaWorld. They have no more gut themselves. It was a calm day on the Pacific Ocean. It’s no different for a whale fall—given enough time, nature uses everything. We depend on ad revenue to craft and curate stories about the world’s hidden wonders. There was a case when people went near to this dead whale and stand on it. Narrator: With so many animals feeding on the carcass, it can degrade in less than a decade and considering how vast the ocean is, stumbling on one only months after it died is really lucky. Narrator: This is a dead whale, which scientists recently discovered at the bottom of the Pacific Ocean covered in all kinds of creatures from bone-eating worms to deep-sea octopuses.
