What type of sharks are best for shark fins?
Shark fins have very little flavor of their own and simply pick up the flavor of the other ingredients. A fairly wide variety of sharks (and other sharklike creatures, like sawfishes and shovelnose rays) are used. A dozen or so species lead the list of "preferred" fins, including tiger, mako, and sawfish.
However, in a sense, many of the "best" species are actually the "worst" in conservation terms. The practice of "shark finning" has resulted in a significant decline in the population of some sharks. Tiger sharks, for example, are currently ranked as "near threatened," and sawfish are critically endangered (that's one step above "extinct in the wild").
Do white sharks swim fast or slow?
It actually looks like White sharks swim really slow but they can reach up to the speed of 55km per hour. it depends if they are closer to the surface or at deep waters, if they at shallow waters their top speed is 57-60km per hour, if they are deeper than usual they swim up to about 49-53km per hour.
Can bull sharks breach like great whites?

Can eating shark cartilage prevent cancer in humans?
No, at least there is no reliable evidence to suggest that it does, Numerous studies have been conducted to test this and all have shown no significant improvement against a placebo. Shark cartilage can cause some side effects,
Furthermore sharks are under significant threat from fishing with almost half the species considered endangered with extinction or near threatened. We are at the point where species extinction is on the table and unproven psudoscience preying on vulnerable individuals does nothing but increase commercial pressure on an already vulnerable resource.
The octopii eat chicken and squid. Sometimes they taste like chicken too. Special divers dive down with chickens to feed them. It's a long process but very useful.
other sharks such as the great white shark or elephant seals
Their sense of smell is so acute that they can detect a drop of blood dissolved in over one million gallons of water! And they can hear can detect a struggling fish over two kilometres away.

No, although they are 'Near Threatened' which is very close to becoming endangered.
How many limbs do a grey nurse shark have?
The grey nurse shark has fins, not limbs. They are Pectoral, Dorsal, Second Dorsal, Anal, and Caudle fin (tail).
Sturgeons are not a natural prey of sharks, for two main reasons:
a) The sturgeon is a salt and fresh water bony fish (it is considered a «living fossil»).
Pups and youngsters live mostly in cold water rivers until maturity, where the bull shark is absent (beeing the most common fresh water shark predator, it lives in warm waters, avoiding the very cold to temperate waters that are the usual habitat of the sturgeon).
b) A few (not all!) sturgeon species may migrate to coastal northern Atlantic ocean, in North America, in high latitude Europe and Asia, when they reach maturity.
At that point, adult sturgeons are too large to be an easy prey of any shark, and larger species (like the Beluga Sturgeon) can reach a total lenght of 5 metres, or even larger.
