About this species
Discosoma nummiforme is a species of cnidarian in the genus Discosoma and is relatively small in size and dimensions, while also possessing a pentagonal-shaped disk, the species itself very rarely exceeds past 2 inches in diameter, however, it is compensated for the variety of colours it exceeds throughout specimens. The species was first discovered at the Adolphus Island in Torres Strait by Rüppell and Leuckart in 1828.
