What is a common trait of opportunistic species?

A common trait of opportunistic species is high offspring production. These species are typically characterized by their ability to exploit environments that are unstable or unpredictable. By producing a large number of offspring in a relatively short period, they increase their chances of having some individuals survive to adulthood, even in fluctuating conditions. This reproductive strategy enables them to take advantage of temporary resources or favorable conditions when they arise, enhancing their likelihood of thriving in various habitats.

In contrast, traits such as a long life cycle, high parental investment, and low reproductive rates are more commonly associated with equilibrium species, which tend to invest more resources in raising fewer offspring to increase their survival in stable environments.
