“It would be a gigantic failure for humanity that would affect everything from coral reefs to food security and climate change. Once sharks are gone, there is nothing we can do to replace the critical role they play in the balance of the oceans.” What would happen if we had no sharks? “If the sharks […]

Sharks are fish. They live in water, and use their gills to filter oxygen from the water. Sharks are a special type of fish known because their body is made out of cartilage instead of bones like other fish. What determines if a fish is a shark? Body shape. If you look at most fish […]

Sharks are Apex Predators This is because they have very few natural predators. A cascade effect naturally occurs in a balanced, healthy ecosystem, whether it be marine or terrestrial. Why are sharks so good predators? Great white sharks are athletic hunters, leaping completely out of the water as they attack prey from below. They have […]

Sharks, always the superlative, are about 10,000 times more sensitive than any other animal with an electric sense, and much more sensitive than even our best measuring equipment. Are sharks afraid of electricity? Sharks have an innate ability to detect electric fields, useful for sensing the bioelectric activity of their prey. Researchers discovered that strong […]

Sharks are among the world’s most misunderstood creatures. Unlike the scary image of sharks portrayed in our movies and television shows, sharks are extremely fascinating animals. Are sharks amazing? Great white sharks could help scientists discover a cure for cancer and it’s all down to their genes. Scientists have been researching the predators’ genes and […]

Smell is incredibly important to sharks and how they use this sense is quite fascinating. Just under the snout of a shark are two small openings, or nares (nasal cavities). Each nare consists of two more openings. Water goes in the one opening and out the other. Do sharks have a powerful sense of smell? […]

Acoustic Senses Sharks have only an inner ear, which consists of three chambers and an ear stone called an otolith. A shark’s inner ear detects sound, acceleration, and gravity. Sharks use sound to locate food. Sound is often the first sense a shark relies on to detect prey. How do sharks use their sense of […]

As in humans, the shark’s inner ear also controls balance. Sharks seem to hear sounds best in the range of 20-300 Hz, and are especially attracted to irregular sounds at or below 40 Hz, which is about the range produced by struggling fish. Do sharks react to sound? Sharks have an acute sense of hearing […]

In addition to those we have – sight, hearing, touch, smell and taste – sharks have two other senses, mediated by specialized receptors: electroreceptorselectroreceptorsElectroreception and electrogenesis are the closely-related biological abilities to perceive electrical stimuli and to generate electric fields. Both are used to locate prey; stronger electric discharges are used in a few groups […]

Great White Sharks (Carcharodon carcharias) became the ocean’s top hunters through the evolution of supremely-adapted senses and physiology. SMELL The most acute sense of the Great White Shark is smell. Do sharks have good sense? Sharks have six highly refined senses: smell, hearing, touch, taste, sight, and electromagnetism. These finely honed senses, along with a […]

Shagreen. Shagreen is a type of rawhide consisting of rough untanned skin, historically from a horse’s or onager’s back, or from shark or ray. What is the name of shark skin? dermal denticlesShark skin is covered by tiny flat V-shaped scales, called dermal denticles, that are more like teeth than fish scales. These denticles decrease […]

A study by the University of Exeter and the Marine Biological Association of the United Kingdom found that sharks, like humans, display introverted and extroverted-like qualities. What personality type is a shark? SHARK – The hard-driving, in-your-face, results-oriented people. What primarily motivates them is money, recognition, and significance. What are 5 characteristics of a shark? […]

Shark symbolizes authority, curiosity, efficiency, connection, guardianship, innovation, knowledge, mystery, observation, power, perception, protection, superiority, movement, and self-defense. What do sharks symbolize in dreams? Dreaming of sharks can mean that you feel there is an immediate threat close to you. In this case, sharks represent a powerful enemy or obstacle that has you frozen in […]

Sharks might look smooth and sleek from a distance, but they are actually covered in hard armour. Unlike bony fish that have flat scales, sharks have microscopic tooth-like scales called dermal denticlesdenticlesDenticles, also called serrations, are small bumps on a tooth that serve to give the tooth a serrated edge. In paleontology, denticle characteristics such […]

Sharks do not have bones. They are a special type of fish known as “elasmobranchs”, which translates into fish made of cartilaginous tissues—the clear gristly stuff that your ears and nose tip are made of. This category also includes rays, sawfish, and skates. What makes a shark different? Sharks are fish. They live in water, […]

In a physical confrontation, a shark defends himself using a variety of tactics. Using a combination of powerful body slams and vicious bites, sharks pummel, disorient and tear apart their enemies. How do tiger sharks defend themselves? Answer and Explanation: Tiger sharks defend themselves in the same way that most other sharks do, either by […]

They can sense electrical fields in water. This ability is known as electroception, and great white sharks are very good at it. They can sense one millionth of a volt in water! The main purpose of this ability is finding prey, as it means that sharks can sense the electrical fields of marine animals. Do […]

Sharks don’t have any bones and their bodies are made up entirely of cartilage – similar to the stuff human ears and noses are made from. It’s strong and flexible, which allows the shark to turn quickly when chasing prey. Sharks need to keep water moving over their gills to get the oxygen that they […]

Shark meat is common and popular in Asia. Shark meat is typically consumed in prepared forms in Japan, such as in prepared fish sausage, surimi, fish paste, fish balls, and other products. Shark meat is popular in Australia, where it is known as flake. Is shark meat a delicacy? Shark meat has been eaten by […]

A new study released by the Atlantic White Shark Conservancy showed that great white sharks off the Cape Cod coast spent about half their time in shallow waters less than 15 feet deep. The study, published in March in the journal Wildlife Research, was based on shark tracking research done in 2017. How shallow of […]
