This question makes no sense. So I will try to answer. Great sharks are always.
The Great Barrier Reef is home to approximately 1,500 species of fish, 400 types of coral, and a diverse range of marine animals, including sea turtles, dolphins, and sharks. It is estimated that about 10% of the world's marine species can be found within this ecosystem. This biodiversity makes the reef one of the most important marine environments globally.
No they are predators which makes them consumers.
Both. Sharks never stop swimming. They hunt mainly by smell and vibration, so night or day makes no difference.
Answer
No, sharks are not evil. They are simply apex predators that play a crucial role in maintaining the balance of marine ecosystems. Misunderstanding and fear of sharks often stem from sensationalized media portrayals.
They have a very good technique for cathcing their food. Stealthy and fast they come at their prey from beneath, before the creature is able to react. This makes the great white sharks great hunters. And another factor is that they have a great sense of smell, thus enabling them to feel bloodscent from several miles away. This way, they are able to find presumably wounded prey that makes an easier catch. They wont react to the smell, however, if they are not motivated by an empty stomach.
Game Shark is a company all on it's own, so Game Shark makes Game Sharks.
No, humans don't have much impact on the Shark's habitat.
well a marine bioligist makes about 200,500 a year
Changes in the environment, such as temperature, lack of food or stronger currents can cause sharks to adapt.
yes, it makes the shark lighter
