It is important to note that a keystone species does not even need to go extinct to affect the environment. /Type /Page Keystone species are important to the point that their very existence is crucial to their ecosystems survival. Keystone species maintain the local biodiversity of an ecosystem, influencing the abundance and type of other species in a habitat. So, by eating mice, cats are actually helping the ecosystem serving as the keystone species. Hence, they are the keystone species. Starfish is a predator that feeds on mussels in the deepwater, thereby maintaining the ecosystem. As they move from plant to plant, they carry pollen. As long as they can fulfill that role, they are still keystone species. Having too many of one can cause problems with the population. In such a case, the starfish may not be a keystone species but act as Indicator species that will indicate very sensitive environmental changes in its ecosystem, or can act as flagship species by symbolizing an environmental habitat. And also, as an indirect result of this, the population of other species like the Sheephead fish, large species of Snails, etc. The female birds of this type will show off a gray-tinted white throat.
