Blue Shark – $15.35 per kg Blue shark is a controversial fish when used as a meat source because the populations are low in the oceans and fishing for them is discouraged and looked down upon. Are blue sharks rare? Blue sharks are a very common bycatch in high-seas longline and driftnet fisheries. They are […]

Although sharks don’t have any visible ears, they are no more deaf than they are blind. Sharks have an acute sense of directional hearing that enables them to detect low vibration frequencies and locate potential prey. Are sharks blind? Sharks are not blind, and their vision is far better than we can imagine. While sharks […]

Sharks have two nostrils (called nares) below their snout that are used for smelling, but they don’t join up to the back of the throat like our nose does, so they can’t sneeze like we do. If something floats into their nares, they might try to shake it out. Sharks breathe through the gills at […]

Even though sharks have jaws made of flexible cartilage that are capable of detaching from the skull (chondrocranium), powerful muscles attach the jaws to the skull and allows them to exert high biting force. Why do sharks jaws come out? In sharks, the upper jaw rests below the skull, but can be detached when the […]

Basically, this means that in situations when personal deterrents (such as the Ocean Guardian Scuba7) do not prevent bites, shark bite injuries can be reduced through puncture-resistant fabric such as Kevlar neoprene. What material can sharks not bite through? Shark Stop developed what they call a space-age polymer nanofibre technology, which is resistant to shark […]

A really well made suit MIGHT be able to withstand being punctured by a white shark, but chainmail does not protect at all from crushing or twisting forces. Doesn’t really matter whether it’s teeth break your skin or not if it rips your arm off and crushes the bones to powder. Why do shark divers […]

Sharks can slosh water around in their mouths to manipulate food to some extent, but swallowing is another matter. They may compensate by using the muscles of their pectoral girdle – the equivalent of our shoulders – that supports and powers the anterior ns during swimming. How do fish eat without swallowing water? For fish, […]

But when a team of scientists recently sent down camera-equipped robots, they not only found animals surviving in and around the volcano; they found a surprising amount of biodiversity, including silky sharks, hammerhead sharks and the rarely seen Pacific sleeper shark, which had previously been caught on video just What sharks live in lava? Scientists […]

Some species are ‘hypnotised’ when they are turned upside down. Sharks’ noses are full of nerve endings, and rubbing them is said to scramble their sensory system. Are sharks sensitive in the nose? Sharks have a complex electro-sensory system. Enabled by receptors covering the head and snout area. These receptors sit in jelly-filled sensory organs […]

When the shark population decreases, the prey that are usually being hunted by them drastically increase in population. This causes the prey to then overeat the next level on the food chain, thus throwing off the entire ecosystem and driving multiple species to extinction. Why is shark finning so bad? Shark finning alone kills 26 […]

Sharks do not rely on two sets of teeth – they have an endless supply of teeth, with a dentition that regenerates constantly throughout life. How many times can shark teeth regrow? Sharks have the ability to continuously regenerate their teeth. They lose at least 30.000 teeth over a lifetime, but each lost tooth can […]

Sharks continually shed their teeth; some Carcharhiniformes shed approximately 35,000 teeth in a lifetime, replacing those that fall out. There are four basic types of shark teeth: dense flattened, needle-like, pointed lower with triangular upper, and non-functional. How many teeth can sharks replace? They lose at least 30.000 teeth over a lifetime, but each lost […]

Basically, this means that in situations when personal deterrents (such as the Ocean Guardian Scuba7) do not prevent bites, shark bite injuries can be reduced through puncture-resistant fabric such as Kevlar neoprene. Are there shark proof suits? We are the world’s leading developer of Shark Bite-Resistant wetsuits using new polymer fibre technology, with more than […]

Bacteria will eat the shark’s meat and bones, and the sharks skin and fins will be eaten by marine life like worms, scavenging fish, or crustaceans. The last remains of a dead shark will be eaten by bacteria and small marine life for many months or years. What do they do with dead sharks? When […]

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 […]

“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 […]

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 […]

“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, […]
