Sharks

Bull sharks are a common and aggressive species that tends to live in highly populated areas such as tropical shorelines. They like shallow waters and are likely the kind of sharks that attack humans most. Bull sharks can live in freshwater or saltwater and do tend to live in some rivers and lakes as long as they are deep enough (about 150 meters). They can live in the coral reef areas at times if it is close enough to the shorelines.

a dorsal fin is the one (or more) located on the back of a fish or aquatic mammal - its the fin that you see when a shark is swimming just under the surface of the water. Ventral fins are the ones toward the rear of the body and help in steering the animal through the water

Sharks are cartilaginous fish. The term "cartilaginous fish" means that the structure of the animal's body is formed of cartilage, instead of bone. A shark does not have one bone in it's body. It's skeleton is made up of cartilage. Cartilage is a tough material, like the material that shaped your ear.

Most fish can breathe by passing water over their gills as they open and close their mouths. Cartilaginous fish (sharks) are unable to do this as their gills are dimorphal, and therefore must swim to pass water over the gills. Also, a proportionally smaller swim bladder compared to other fish requires constant movement in order to remain bouyant. This process is called locobouyosis.

Sharks, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.

there are at least three non-carnivorous sharks; the whale shark (Rhincodon typus), the basking shark (Cetorhinus maximus), and the megamouth shark (Megachasma pelagios) are filter feeders and feed on phytoplankton.

A shark will grow in a tank until it fits, meaning it will only be as big as the tank permits while still being able to swim freely. it depends of the size of the tank ,the kind of shark ,how much food and how many sharks

The lifespan of a shark varies by species. Some species, like the Greenland shark, can live over 400 years, while others have shorter lifespans, typically ranging from 20 to 30 years. Factors such as habitat, diet, and species-specific characteristics can influence a shark's lifespan.

Yes. Think about it. A few years ago a whale swam all the way to Sacramento. I would suspect the most likely shark to worry about would be the bull shark. They are infesting the rivers of the Amazon and in Australia and they are known to swim inland in Santa Cruz/Monterey area. Fear the bullshark.

Sharks cannot stop moving because they always need oxygen flowing through their gills. Unlike other fish, who are able to "pulse" their gills in order to keep water and oxygen flowing through their gills, sharks are unable to do so and therefore have to keep swimming.

Sharks generally live from 20 to 30 years. The spiny dogfish shark and the whale shark have been known to live over 100 years.

The bite radius depends upon the size and species of the shark. The larger breeds can have a bit radius of up to 40 centimeters when full grown.

Crocodiles lay eggs. The mother crocodile builds a nest and deposits her eggs there, which she guards until they hatch.

Predators of the goblin shark include larger sharks, such as great whites or tiger sharks, and possibly some deep-sea predators like sperm whales. However, due to its deep-sea habitat and elusive behavior, the goblin shark doesn't have many known predators.

sharks are mostly at the top of the food chain but humans are indeed its main killer its sad millions of sharks are slaughtered for a small part of there body that is used in shark fin soup but the oils in a sharks skin can lead to death in time

Sharks are ectothermic, meaning they rely on their environment to regulate their body temperature. Warm waters help sharks maintain their metabolic processes, allowing them to hunt, digest food, and reproduce efficiently. Additionally, warm waters tend to be more nutrient-rich, providing sharks with ample food sources.

It is estimated that around 17 species of sharks have gone extinct. These extinctions have been mainly caused by overfishing, habitat destruction, and climate change. Efforts are continuing to protect and conserve the remaining shark species to prevent further extinctions.

Sharks obtain food through various hunting techniques, such as ambush predation, scavenging, and hunting in packs. They primarily use their acute sense of smell to detect blood in the water and their keen eyesight to locate prey. Once they have located their target, sharks use their powerful jaws and sharp teeth to catch and consume their food.

saving sharks is very important. they are top ocean predators. the oceans cover 75% of the earth. if sharks disappear of their exisitance diminishes certain fish populations will explode. for example sting ray populations around the chesapeake bay will grow, when they enter the bay they will eat all of the shell fish (aka-oysters) this has numerous affects. no oysters for you sea food lovers, fewer pearls for those who like jewelry and an unhealthier bay. all because some one wanted sharkfin soup. and that is just on a small scale global effects could be devastating.

no sharks actually mistack humans for seals in there wet suite eg. jhony want to surf in his BLACK wet suit (the colour of seals) and a shark came up and ate him and his BLACK wet suit so really no sharks acculy think that we taste TERRIBLE and we do
No. When a shark sees a human swimming the shark confuses it with a fish and bites it. Soon it realizes that it is not a fish a spits out the human it had chewed.

A pool shark is a hustler, someone who acts like they have no idea how to play a game but really they do. They earn money by playing a game and losing really badly, but then the agree to play you again but they bet you alot of money and then if you agree they play their best and win the cash

it depends on the shark you are asking about. Most sharks want to swim alone because they want food to themselves and they are very vain. Some sharks swim in groups though. Only to be tougher then 1 shark is. But most of the time, a shark will swim alone.
