Interestingly, basking sharks have almost completely lost their teeth. What they do have are hundreds of tiny, curved teeth that are no longer useful for capturing food.
Unlike humans, all sharks are born with teeth. They grow in conveyor-belt rows, with the biggest teeth facing outwards. Over time, the smaller teeth in the back move up, replacing the front ones. Most sharks have between 5-15 rows, and the whale shark has a whopping 3,000 teeth in its mouth!
Shark teeth can be replaced within a day of losing their tooth. Sharks are born with complete sets of teeth and will immediately swim away from their mothers to begin hunting for food on their own. Humans need fluoride from outside sources, but shark teeth contain their own fluoride. Sharks can't get cavities.
Sharks eat fish, crustaceans, mollusks, plankton, marine mammals, and even other sharks. Their strong sense of smell allows them to detect blood in the water miles away. Most sharks are cold-blooded. But some sharks, such as the great white shark, are warm-blooded, which enables them to grow and swim faster.
dogfish, (order Squaliformes), any of several small sharks making up an order of chondrichthyian fishes composed of the families Centrophoridae (gulper sharks), Dalatiidae, Echinorhinidae, Etmopteridae, Oxynotidae, Somniosidae, and Squalidae. In North America the name is also used for a freshwater fish, the bowfin.

Whale sharks are essentially bulletproof, with six-inch-thick skin. Though it's not the thickest in the animal world (sperm whales have skin measuring more than a foot thick), but it's tough enough that it's made it extremely difficult for scientists to get a blood sample of the creature.
The nursehound (Scyliorhinus stellaris), also known as the large-spotted dogfish, greater spotted dogfish or bull huss, is a species of catshark, belonging to the family Scyliorhinidae, found in the northeastern Atlantic Ocean....NursehoundFamily:ScyliorhinidaeGenus:ScyliorhinusSpecies:S. stellarisBinomial name
Sand shark is just what people call small sharks they don't know the name of. Dogfish do not have teeth, and is one of the easier ways to ID them.
Sometimes though the adult tooth will erupt behind the baby tooth, and this can be quite a cause for concern for many parents. We call these special (but actually quite common) cases “shark teeth,” and usually they are no big deal.
What Can Be Done About Shark Teeth? The way you handle shark teeth depends on the baby tooth. If it's even a little loose, have your child try to wiggle it several times a day to further loosen it. In many of these cases, the baby tooth will eventually fall out on its own, and the permanent tooth will move into place.

There haven't been any reported cases of basking sharks consuming humans to this point, although some divers have gotten within mere inches of the massive sea creatures! The Basking Shark mostly eats plankton and small fish, and it's very likely that the species will deviate much from its regular diet.
Bull huss are closely related to the Lesser spotted dogfish. They are not generally targeted by Cornish fishermen although their meat is good to eat, as it is extremely hard and time consuming to remove their tough abrasive skin.
Cut on either side of the V (which will expose the backbone), then cut the head off. Starting at the head, tear the skin off. Cut along the backbone, and remove the fillet of meat on one side. Turn the fish over, and cut away the other fillet.
sand shark, any of three species of sharks of the genera Carcharias and Odontaspis in the family Odontaspididae. Sand sharks are found mainly in shallow water, usually at or near the bottom, along tropical and temperate ocean coastlines. Sand sharks are potentially dangerous to humans.
Despite their small size, spiny dogfish are aggressive and have a reputation of relentlessly pursuing their prey. The name "dogfish" stems from their habit of feeding in packs — sometimes numbering in the hundreds or thousands. They'll eat almost anything they can get their strong jaws and teeth on.
The speartooth shark (Glyphis glyphis) is one of the rarest shark species on earth, found only in tropical rivers in New Guinea and northern Australia. The speartooth shark is not targeted by fisheries for its meat or fins, but it may be accidentally caught in fishing nets as by-catch.
bull sharksHuman Encounters. Because of these characteristics, many experts consider bull sharks to be the most dangerous sharks in the world. Historically, they are joined by their more famous cousins, great whites and tiger sharks, as the three species most likely to attack humans.
At least 21 varieties of shark species are thought to live around Britain's coastlines all year round. “The closest verified sighting was in the top of the Bay of Biscay, but there has been no confirmed sightings of white sharks in UK waters despite suitable habitat.”
A fish with human-like teeth has been caught in the United States. A photo of the fish was shared on Facebook this week by Jennette's Pier, a fishing destination in Nag's Head, North Carolina. It was identified as a sheepshead fish, which has several rows of molars for crushing prey.
The last sets of baby teeth to go are the canines and primary second molars. The canines are usually lost between the ages of 9 and 12 years old, while the primary second molars are the last baby teeth that your child will lose. These final sets of teeth are usually shed between the ages of 10 and 12.
Fortunately, shark teeth are not dangerous and are not something you need to be too worried about. In many cases, the tooth will get loose as the permanent tooth comes in. Many children will start to wiggle the tooth on their own. If they can wiggle it out, then the problem can be resolved without intervention.
Humans only get two sets of teeth in their lifetime: 20 primary (baby) teeth and 32 secondary (permanent) teeth. If you lose any of your secondary teeth, your teeth will not grow back a third time.
The baby teeth — otherwise known as the primary teeth, milk teeth, or deciduous teeth — are the first set of teeth to erupt in the mouth. These teeth are known for having those thin, thread-like roots.
Calling nurses “sister” or “matron” may be deterring men from joining the profession, the head of the Royal College of Nursing has warned. In Scotland, and in some English NHS trusts, the term “sister” has already been done away with and everyone in the role is referred to as a charge nurse, she said.
Phobophilia, which literally translates to "love of fear," from phobo meaning fear and philia meaning love, would fit in nicely. A person who loves the disturbing and horrifying, then, may be known as a phobophile.
The Emperor usually picks his most favored son as the Crown Prince(太子). The Emperor's other sons “Princes” are called “皇子” (huang zi) and they usually keep their title as such until they come of age(adulthood) and gain another title: “郡王” (Jun Wang) which is the first and lowest rank of Prince.
