Summary: Bans on shark fishing are only partially effective in protecting sharks, new research suggests. Bans on shark fishing are only partially effective in protecting sharks, new research suggests. What is being done to stop shark finning? In 2021, Congress reintroduced the bipartisan Shark Fin Sales Elimination Act (H.R. 2811/S. 1106), which would ban the […]

As apex predators in many ecosystems, the disappearance of sharks is causing dangerous imbalances in marine communities worldwide. Without sharks, the health and productivity of our oceans—and dependent livelihoods and economies—are at risk. Why shouldnt we kill sharks? Consuming sharks will increase the level of mercury you ingest which will in turn increase your risk […]

As an apex predator, their continuing eradication threatens the health of the entire marine ecosystem. Make sure you avoid shark fishing because even catch and release is harmful to sharks. If enough anglers stop fishing for them, it will give shark populations a chance to rebound. Does hooking a shark hurt it? Embedded hooks can […]

megalodon was not only the biggest shark in the world, but one of the largest fish ever to exist. Estimates suggest it grew to between 15 and 18 metres in length, three times longer than the largest recorded great white shark. Is there a shark bigger than the megalodon? What is bigger than the megalodon […]

“Hammerheads are the most advanced species and they’re also the youngest (on the evolutionary timeline). “They have more sensory adaptations and more neural linkages in the brain which is why they gather socially, unlike other sharks. They’re kind of like chimpanzees of the shark world. What type of shark is the smartest? As large predators, […]

Here are 7 reasons why this practice should be banned. Our most ancient species are endangered. The soup isn’t that good anyway. Changing shark populations destabilizes marine ecosystems. This isn’t just in Asia. Finning cashes in on cruelty. It’s a wasteful practice. Longlining is killing more than sharks. What are the negative effects of shark […]

What happens when shark finning continues? Let’s assume sharks disappear and therefore another fish can overpopulate the reefs, let’s say this fish feeds primarily on juvenile reef fish. Meaning the population of reef fish will decline quite fast which means coral reefs will suffer. How does shark finning affect us? For instance, the loss of […]

According to the report, a nationwide ban on the trade of shark fins would reduce the international fin trade, improve enforcement of the current finning ban, and reinforce the status of the United Statesthe United StatesThe United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is […]

Shark culling has been criticized by environmentalists, conservationists and animal welfare advocates—they say killing sharks harms the marine ecosystem and is unethical. Government officials often cite public safety (attempting to reduce the risk of shark attacks) as a reason for culling. Why should we stop shark culling? Shark culling also kills innocent turtles and dolphins […]

They don’t produce milk, they don’t have hair, and most of them are cold-blooded. Do sharks produce milk? Sharks are not mammals; sharks are fish. Sharks lack mammalian characteristics such as hair and lungs, and do not produce milk. Do sharks give milk to babies? GREAT WHITE SHARK PRODUCES “MILK” TO FEED ITS BABIES The […]

Shark nares are used only for smelling, and not for breathing the way we use our noses. And just in case you are still wondering how sharks smell… they smell a bit fishy! Do sharks have a smell? They’re super-sensitive to smells that are important to their survival. Including scents produced by potential predators, prey […]

Lemon sharks are rendered harmless when flipped on their backs. These kings of the ocean go limp after about 15 seconds and will play dead long enough for scientists to conduct experiments on them. Lemon sharks play dead when flipped on their backs. Why do sharks play dead? Tonic immobility is a natural state of […]

Explainer: How a fossil forms Much later, about 66 million years ago, a huge asteroid fell to Earth. It killed off most dinosaurs — and 30 to 40 percent of shark species. What killed the sharks 19 million years ago? Analysis of the fossil record shows a mysterious mass extinction that decimated the diversity of […]

Some 37% of the world’s sharks and rays are considered in danger as of 2021, up from 33% seven years ago, the IUCN announced. Overfishing, a loss of habitat and climate change explain the upward trend, it said. Oceanic shark populations have dropped by 71% since 1970. How many sharks are left in the world […]

A study published by an international team of scientists last week in the journal Nature found the global abundance of oceanic sharks and rays has plunged more than 70% since 1970. In the early 2000s, up to 273 million sharks were killed every year, the study says. Are sharks becoming overpopulated? Global shark and ray […]

“They are inquisitive, sharp and sentient beings,” Dr Aich says. “Sometimes I go down in the water after baits have been thrown, and the shark doesn’t come to the boat. Or she will come for a few seconds and go away. The shark’s will to encounter humans is pivotal.” Are sharks self aware? As creatures […]

Subduing them minimises their struggling and reduces the possibility of injury. When the shark is gently turned on their back, it’s thought to disorientate them, causing them to enter the state. The shark’s muscles relax and their breathing becomes deep and rhythmic. What happens to a shark when you turn it upside down? Sharks go […]

The unfortunate truth is that your favorite and most used products could contain shark, labelled as squalene, a compound made from shark liver oil. Squalene is a common ingredient in lipsticks, foundations, eyeshadow, moisturizers, sunscreens, and lip balms. Are sharks in makeup? Much of the squalene and squalane found in cosmetics is made from shark […]

It’s a feat for the next decade. A shark skin-like material might also serve as a line of defense against biofouling, or the accumulation of algae and barnacles on the bottom of ships. Most anti-fouling paint is toxic, so artificial shark skin could provide an environmentally friendly alternative. What is special about a sharks skin? […]

Sharks play a crucial role in marine ecosystems In an algae-dominant ecosystem, the coral reefs can’t compete and will cease to survive. Shark conservation is important because these types of negative environmental changes could take place if they were to decrease in numbers. Why is it important to make sure that sharks do not become […]
