Are sharks stronger than humans?
It depends on the size. Sharks are much more muscular than stingrays.
In a fight, if they are the same size, the shark would probably win. A large stingray might fight off a shark, but the stingray does not have the same strength, and stinger barbs do not do the same damage as teeth. It would depend on the type of shark and how hungry it is.
Most of the time, sharks and stingrays coexist.

Where do you find a norweegan gorilla shark tooth?
Shark teeth are the only part of a shark that turns into a fossil. Sharks do not have a bony skeleton, but one made of cartilage. You can find shark teeth either by walking along the beach and looking for them, or by diving to the bottom of the sea. It is easiest to find them on the beach! Look for the triangular shape, then see if it is a very glossy black color. Fossil seashells are also black, and pieces of them come in all shapes, but they do not shine as much as a shark tooth. The tooth will also usually have a rougher patch at one end, which is where it joined the shark's gums.

Why does a shark is able to stay underwater for a long time but a whale cannot?
Sharks and whales have completely different structures and organs. A shark is actually a fish and has gills, while a whale is a mammal and can only breathe with its lung like all mammals. Fish have gills to allow them to breathe underwater. Sharks do not need to come to the surface to breathe.

Do sharks need to swim constantly?
Some species of sharks need to swim constantly and some don't. This is related to both breathing and buoyancy.
Sharks have gills to extract oxygen from water and most species of sharks employ buccal
pumping to push water across the gills when needed as a supplement to the flow of water that occurs while swimming. Water flow to the gills while swimming is called called ram ventilation and the most effective way for sharks to get oxygen.
There are over 470 shark species and about two dozen have lost the buccal
pumping ability and so must swim or die from lack of oxygen. This group are known as obligate ram ventilators and includes hammerheads, great white sharks, mako
shark, the salmon shark and the whale shark. Nurse sharks are quite the opposite, effectively using buccal
pumping to breathe and able to lie motionless on the ocean bottom for extended periods.
Unlike most bony fish, sharks do not have an air bladder to maintain buoyancy. Different species of sharks have various substitute buoyancy adaptations, but for many, swimming also keeps them from sinking and helps maintain vertical orientation.

Where can you find tons of fossil shark teeth in the US?
Fossil shark teeth can be found in abundance along the coast of states like Florida, Georgia, and South Carolina. Popular fossil hunting spots include Venice Beach in Florida and the Peace River in Florida. Additionally, sites like Calvert Cliffs State Park in Maryland and Aurora, North Carolina are known for yielding large quantities of fossil shark teeth.
Yes, because they bite off very large chunks of their prey.
Sharks have 5 or more rows of teeth. Humans only have 20 baby teeth and 32 adult teeth. Sharks can re-grow teeth. Humans only get 2 sets (milk teeth and permanent teeth). Sharks have serrated edges on their teeth. Shark teeth are not attached to the jaw. Humans bite and chew with their teeth. Sharks use their teeth to rip their prey apart.
What kind of scales does a shark have?
Shark skin looks and feels like it is covered with tiny teeth. In fact, their small, rough placoid scales (also called denticles), have the same structure as sharks' teeth! Shark skin is sometimes used as sandpaper.
