When many think of sharks, they think of the movie Jaws or a dangerous man-eating fish. In reality, sharks is a large group of fish that includes very small to much larger fish. Some can be harmful to man and others are harmless. To delve into this interesting and diverse group of cartilaginous saltwater fish that have sharp teeth and a bad reputation, ask your questions in this category.

How are a crab and a shark alike?
Crabs and sharks are both aquatic animals, but they belong to different taxonomic groups. Crabs are crustaceans, while sharks are cartilaginous fish. Both have adapted to their marine environments with specialized body structures and behaviors, such as the crab's hard exoskeleton and the shark's streamlined body for swimming. Despite these differences, both animals play important roles in their respective ecosystems as predators.
Can sharks live in brackish water?
YES! Bull sharks mainly stay in brackish waters. They have the ability to swim up the river. Bull sharks have been found at the end of the Mississippi river in the Northern Part of America.
Are hammer-head sharks still alive?
Hammerheads are one of the medium sized species of sharks, which make them an easy target for fishermen. Their fins are a delicacy. As a result of overfishing, hammerhead numbers have fallen drastically in many of their habitats. Fishermen usually cut off their fins and toss the remainder of the fish into the sea to die a horrible death. Loss of habitat is another danger to these sharks. Because of widespread uncontrolled hunting, hammerheads are considered an "endangered" species. Unless hunting them is stopped soon, these species may become extinct very soon.
How old is the oldest scalloped hammerhead shark?
I know their was a hammerhead caught of of The Rod n, Reel Pier that measured 18'7" long. The pier is located on Anna Maria Island, Florida. Also a large great white was caught either on that island or the island just south of it. The TIGER shark used for a brief part of the first "Jaws" was caught in Long Boat pass between Anna Maria and Long Boat Key.
My name is Alex Higgins and I love shark trivia.
They have been known to sculpt glasses out of silt and clay found on the ocean floor, put the cups on their dorsal fin, and swim at the top of the ocean during rainstorms. They then take the cup full of rainwater, and enjoy!
Where is the bull sharks in the food chain?
Bull sharks have been known to kill humans, & are right up there w/ great white & tiger sharks, possibly because bull shark attacks are more easily documented than attacks by other species of similar power, like duskies, makos, & grey reef sharks. That's because bulls spend more time in fresh water, making attacks in such areas no brainers.
Bulls are NOT at the top however. I'm not sure of the source, but I read of a tiger shark w/ a bull shark in its gut, which in turn ate a blacktip, which in turn ate a dogfish.
Which raises the question.."Is the tiger the blacktip's frind? Is the bull the dogfish' friend? Who's the lonely bull's friend?" lol

What kind of sharks can you put in a 30 gallon aquarium?
If the tank you are talking about is fresh water tropical with a temp of 75 degrees, with a few dark areas so the shark you select has a place too hide, "a fresh water shark is shy" you can select any of the popular ones from your pet store, just remember, big fish, eat little fish, if you purchase a small shark and you have large fish in your tank.
You can also have a nurse shark which is the safest. But you'll need something bigger than a fish tank =)
SuperSlasher
Answer. Leopard sharks and Cat Sharks are commonly placed in salt water aquariums. They are very small and adapt well to aquariums.
Madlizzie
You could also havae a dogfish in there but not in the same tank make sure the tank is a lot bigger than the shark
in a tank as big as it. you'll need to check up that on google or someplace like that for the open the oacen

Why don't the sharks eat the other fish in the national aquarium?
Fish and sometimes people if they get too close.
Has there ever been a fatal shark attack in turkey?
According to the International Shark Attack File , housed at the University of Florida: The Hammerhead shark has been attributed with a total of 33 recorded attacks since 1580 with no deaths. A Hammerhead Shark grows to around 20 ft. full grown and is the most manueverable of all sharks; attacks have been blamed on adolescent Hammerheads seeking a mate and accidently trying to "nail" a human. The Great Hammerhead is the most dangerous to man.
Is a Betta fish a cartilaginous fish?
No bettas are fish not mammals. Bettas have a labyrinth organ which enables them to breathe air when there is not enough oxygen in the water to sustain them. Here are some things that separate bettas from mammals
Hair. Bettas have no hair or fur
Scales. Bettas have scales, mammals do not
Ability to breathe through gills. Mammals do not have gills, bettas do
Egg laying. Bettas lay eggs, mammals give birth to babies without shells that are able to breathe by themselves
What size is the hamer head shark?
The hammerhead shark is one of the highly interesting shark species because of the unique shape and structure of its head. The hammer-shaped part of the head is scientifically referred to as cephalofoil. This particular part of its body is used for prey manipulation, maneuvering and sensory reception. This particular kind of shark lives in continental shelves and along coastlines where the waters are warmer. Aside from these interesting facts, it is also nice to learn the size of hammerhead sharks.

There are actually nine different species of hammerhead sharks, all of which grow within the range of 3 to 20 feet or 0.9 to 6 meters long. All of their heads resemble a flattened hammer, which set them apart from other shark species. Their uniquely shaped heads allow them to turn sharply while maintaining stability. Likewise, the shape of their heads aids them maneuver and find food.Do fish have a lateral line system?
The lateral line is a system of sense organs; neuromasts situated along/in the lateral line detect movement and vibration in water. The system is important in schooling and predatory behaviour, as well as in general for spatial awareness. It allows detection of movement outside of the range of vision, or in conditions that reduce visibility.
Blind fish will orientate towards movement in the same way as fish that are able to see, but disruption of the lateral line also disrupts the response to movement.
What are three adaptations of a cartilaginous fish?
The chondrichthyans are often thought of as primitive compared to bony fishes . Many chondrichthyans, however, have evolved sophisticated adaptations that have made them successful predators over a wide range of habitats.
sense of hearing
The senses of active predators, including many sharks, are especially well developed. A keen sense of hearing allows sharks to locate prey from as far away as 250 meters (800 feet). They are particularly sensitive to low-frequency vibrations such as those emitted by injured animals. Sound is detected through the ears and through the lateral line , a series of fluid-filled canals along the head and sides of the body that contain sensory cells sensitive to vibrations
sense of Sight
. As in many nocturnal mammals, the inside of a shark's eye is covered with a tapetum , a membrane that reflects light back into the eye, making it easier to see in dim light. Unlike most fishes, sharks can reduce and expand their pupils. In some species, the eyes are protected during feeding by the nictitating membrane, a structure similar to an eyelid.
sense of smell
The Elasmobranchi group has external nostrils on the lower side of the body; because of them, sharks can detect tiny concentrations of substances such as blood, which allows them to scent prey from distances of several hundred feet. Finally, sharks can detect electrical signals via the ampullae of Lorenzini, which are specialized organs distributed over a shark's head that detect changes in electrical currents. Sharks use these to sense the electrical fields emitted by the heart and muscles of their prey.
Shark meat is not poisonous, BUT it is high in urea (sharks store pee as urea in their tissues). So in order for it to taste good, it is usually soaked for a number of hours in water to get rid of the urea.
No because people in China eat shark fin dim sum.(even though it is illegal)
