- ‘Few Great Lakes bird or fish species eat zebras directly, but another Eurasian invader, the round goby, gobbles them up.’
- ‘Warming of the Great Lakes is likely to cause a seasonal decline in algae, an important food source for fish, and could make the lakes more hospitable to invasive exotic species such as round gobies.’
- ‘As it often eats bivalves that filter the water, the round goby is a vector for bioaccumulation of many contaminants.’
