Malo is a genus of box jellies. It contains four species. Malo kingi and Malo maximus (previously Malo maxima, corrected for gender) were described by the Australian marine biologist Lisa-Ann Gershwin in 2007 and 2005, respectively. Both species are extremely venomous Irukandji jellyfish. A third, Malo filipina from the Philippines, was described in 2012, and a fourth species from Northern Australia, the smallest of the genus, was described in 2014 and named M. bella.
