What Do You Know About Sharks

Explanation
The question is asking about the type of animal that a shark is. A shark is an aquatic animal, meaning it lives and thrives in water. Sharks have adapted to their aquatic environment with streamlined bodies and gills that allow them to extract oxygen from water. They are not amphibians, which are animals that can live both in water and on land, nor are they domestic or terrestrial animals. Therefore, the correct answer is aquatic.

Explanation
The correct answer is Pisces. The question asks about the species class that sharks belong to in the animal kingdom. Sharks are a type of fish, and the class that fish belong to is Pisces.

Explanation
The scientific name for shark is Selachimorpha. This is the correct answer because Selachimorpha is the taxonomic order that includes all sharks. It is a scientific term used to classify and identify this specific group of aquatic animals. The other options, Brocolli, Boniface, and Salamanda, are not related to sharks and do not serve as their scientific names.

Explanation
The correct answer is 20 - 30. Sharks have varying lifespans depending on the species, but on average, they can live for about 20 to 30 years. Some species can live longer, while others have shorter lifespans. Factors such as size, habitat, and environmental conditions can also influence the lifespan of a shark.

Explanation
Adult sharks do not have a specific speed limit in the sea. The given question is asking for the speed limit of an adult shark, but there is no set speed limit for sharks as they can swim at different speeds depending on the species and individual factors. Therefore, it is not accurate to assign a specific speed limit to adult sharks.

Explanation
Sea animals and land animals are classified into different categories based on their characteristics and evolutionary history. The given options are different ranks or categories within this classification system. The correct answer, "Superorder," indicates that the shark belongs to a higher rank or category within the classification system. This suggests that sharks have certain distinguishing characteristics that separate them from other sea animals and place them in a higher taxonomic group.

Explanation
The tiger shark belongs to the species Requiem. Requiem sharks are a family of sharks known for their aggressive nature and include several dangerous species. The tiger shark is one of the largest and most powerful species within this family, known for its voracious appetite and ability to prey on a wide range of animals. Its powerful jaws and sharp teeth make it a formidable predator in the ocean.

Explanation
In the pre-historical era, sharks were sometimes referred to as "sea dogs." This term likely originated from the observation that sharks are predators in the sea, similar to how dogs are predators on land. The name "sea dog" may have been used to describe the shark's behavior or appearance, highlighting its powerful and predatory nature in the ocean. Over time, the term "sea dog" may have fallen out of common usage, but it provides insight into how early civilizations perceived and named different animals.

Explanation
Sharks have been around for millions of years and are still in existence today. The evolution of sharks dates back to a period between 420 and 450 million years ago. This suggests that sharks have been able to adapt and survive for a significant amount of time, making them one of the oldest species on Earth.

Explanation
The record states that there are hundreds of shark species in existence, and some are still undiscovered. Therefore, the estimate of known shark species to date would be higher than the options provided. The correct answer is 470.
