Sharks For as long as sharks have existed which is like 400 million years, the ecosystem of the ocean has depended upon the sharks more than any other marine animal. African elephants. The concept of the keystone species was discovered by Professor Robert Paine from the University of Washington while studying sea stars in their natural environment in Makah Bay, Washington. Here is a list of 17 Endangered Species of the Ocean with a short explanation on the reasons why their population is at risk. Antarctic krill use intensive searching and rapid feeding techniques to take advantage of high plankton concentrations. We’d say so. The species was the dodo, a large flightless bird that thrived until Dutch explorers discovered the island in the late 1590s. In a marine ecosystem, or any type of ecosystem, a keystone species is an organism that helps hold the system together.

Instead, they are usually secondary consumers. 1. Keystone Species Definition. When a keystone species is removed from a habitat, the habitat is dramatically changed. They’re also considered a keystone species because of their critical importance to the health and stability of the nearshore marine ecosystem. Sea otters are an iconic species, representing the beauty and diversity of marine life found along California’s coastline. Sharks. Impressive?

A keystone species, by definition, has the power to largely effect entire ecosystems simply by performing natural behaviors for survival. All species in an ecosystem, or habitat, rely on each other. Also, some mutualism would be thrown off because other fish would not be safely swimming next to the sharks. Some ecosystems might not be able to adapt to environmental changes if their keystone species … Keystone Species. If sharks were to be removed from oceans, the oceans would not know what to do!
