What is a sharks niche?
They fill an important niche as a top predator and may help to keep populations of marine mammals in balance. Since they are positioned at the top of the food chain, they are never abundant. As a result, the removal of a few individuals can have a profound effect on the population.
What are sharks habitat?
They are found in just about every kind of ocean habitat, including the deep sea, open ocean, coral reefs, and under the Arctic ice. Wherever they live, sharks play an important role in ocean ecosystems—especially the larger species that are more “scary” to people.
What is the ecological niche of a shark?
As apex predators, sharks play an important role in the ecosystem by maintaining the species below them in the food chain and serving as an indicator for ocean health. They help remove the weak and the sick as well as keeping the balance with competitors helping to ensure species diversity.
What is the habitat of great white sharks?
Great white sharks live in almost all coastal and offshore waters which have water temperature between 12 and 24 °C (54 and 75 °F), with greater concentrations in the United States (Northeast and California), South Africa, Japan, Oceania, Chile, and the Mediterranean including Sea of Marmara and Bosphorus.
What animals eat sharks in the ocean?
Orcas eat great white sharks—new insights into rare behavior revealed. Though the great white is considered the top marine predator, orcas may actually rule the oceans, new observations suggest.
What is the niche of a lion in their habitat?
In their native habitats, lions fill the niche of hunting large herbivores found in the arid savannas of Africa.
What animal family does a shark belong to?
Elasmobranchii
Sharks come from the family Elasmobranchii within the class Chondrichthyes. Members of the Elasmobrandchii family have skeletons made out of cartilage instead of bone. Aside from sharks, this family include rays, skates and chimaera.
Why are sharks an important part of the ecosystem?
Because sharks directly or indirectly affect all levels of the food web, they help to maintain structure in healthy ocean ecosystems. This indirect control on prey species can affect the greater ecosystem. For example, sharks help preserve seagrass meadows by intimidating their prey, turtles, which eat seagrass.
What animals are related to the great white shark?
Shark Relatives These boneless fishes are in a class called Chondrichthyes that includes sharks, skates and rays. Sharks are also distantly related to the mysterious and rare chimaeras, which are found in deep ocean waters. Their enigmatic behavior has earned them names like spookfish or ratfish.
Do sharks have territories?
Though they do not necessarily have territories in the sense that terrestrial predators do, there is a discernible dominance hierarchy among sharks. The system is simple: the largest sharks get the best hunting spots. Incursions by smaller sharks are frowned upon, and intruders are evicted, violently if necessary.
Are sharks prey or predators?
Most shark species are top predators feeding on fish, seals, penguins and even other sharks. Some of the largest species, however, such as the whale shark and the basking shark, feed only on plankton.
Are sharks classified as animals?
No, sharks are not mammals, but actually fall under the category, or class, of fish. All species of sharks are classified as fish, and further fall into the subclass of Elasmobranchii. It has often been questioned why sharks are fish, while other large sea creatures – like dolphins or whales – are mammals.
What kind of habitats do sharks live in?
Sharks have adapted to living in a wide range of aquatic habitats at various temperatures. While some species inhabit shallow, coastal regions, others live in deep waters, on the ocean floor and in the open ocean. Some species, like the bull shark, are even known to swim in salt, fresh and brackish waters.
Why are sharks so good at adapting to their environment?
Sharks are very good at adapting to new situations and environments which is why they have survived in the water for millions of years. The habitat of a shark depends on the species though. Sharks are cold blooded, and that would usually imply that they would search for areas where the temperatures are very cold.
What kind of environment does a bull shark live in?
Freshwater Swimmers – Despite the fact that they can swim in freshwater environments, bull sharks are not freshwater sharks. They are one of the few species that live primarily in saltwater, but can also venture into freshwater. Bull Sharks and Humans – This shark species is very likely to run into humans from time to time.
Are there different types of sharks in the world?
Sharks have different shapes, sizes, colours, fins, teeth, habitats, diets, personality, method of reproduction and other attributes. Some types of shark are very rare (like the Great White Shark and the Megamouth Shark) and some are quite common (like the Dogfish Shark and Bull Shark).
