“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 […]

The removal of top predators such as sharks through fishing and finning, not only results in the destruction of precious carbon sinking herbivorous habitats as explained above, but also in higher biomass of prey animals. This shouldn’t come as a surprise to anyone, fewer sharks equals more prey. How do sharks affect climate change? Sharks […]

In Shark Bay, tiger sharks mainly feed on seacows, which are also known as dugongs. If the sharks were to totally die out, sea cow populations would flourish, and increase rapidly. And, if that were the case, there wouldn’t be enough seagrass to go around, which is a main staple of their diets. How do […]

In the coarser developments of shark skin, it has been used like sandpaper for polishing. However, the finer tanned shark skins are used for shoes, handbags, and other leather items. Highly sought after, these skins are by-products from fishing villages and international cuisine. What can shark skin be used for? Lightweight and wrinkle-free, sharkskin is […]

Tipping the delicate oceanic ecosystem out of balance “If there is a lack of sharks, then fish and other ocean creatures that would otherwise be consumed by sharks will become too numerous and eat too many smaller creatures and so on, meaning that the whole ecosystem changes massively.” Why shouldnt we kill sharks? Consuming sharks […]
