The mosquitofish is a very troublesome invasive species that has unfold from its authentic dwelling in North America to varied locales world wide, together with Europe and Australia.

Being an invasive species, the fish are largely fearless, they usually haven’t any predators within the locations they’ve colonized. Nonetheless, a global workforce of biologists and engineers has discovered an answer to the issue: a robotic.

Again in 2019, Giovanni Polverino—at the moment a post-doc on the College of Western Australia—and his colleagues developed a mechanical largemouth bass that proved to be efficient in scaring mosquitofish. In North America, juvenile largemouth bass repeatedly make meals of the species; the primal worry of this predator has caught with the mosquito fish as they traversed the globe.
