Some examples of keystone species, and why they are considered keystone species Let us start by a pretty common example, such as the grey wolf (Canis lupus). This is an apex predator that feed on large herbivores such as moose, deer and roe deer, and are in many parts of the world important to keep these herbivore populations from growing too high.
The Asteroidea occupy several significant ecological roles. Starfish, such as the ochre sea star (Pisaster ochraceus) and the reef sea star (Stichaster australis), have become widely known as examples of the keystone species concept in ecology.s well as the starfish, the echinoderms include sea urchins, sand dollars, brittle and basket stars, sea cucumbers and crinoids. The larvae of echinoderms have bilateral symmetry, but during metamorphosis this is replaced with radial symmetry, typically pentameric.
