ANS Example

Caulerpa

(Caulerpa Taxifolia)

Nicknamed "killer algae", part of this species success as an invader in non-native habitats is the lack of natural predators. Predation by herbivorous fish and invertebrates is an important controlling factor in the ecology of this alga. C. taxifolia grows unchecked in environments with no natural predators.
