The collapse of the Funda˜ o tailings dam in Mariana (state of Minas Gerais, Brazil, 2015) resulted in a major human tragedy and probably the worst environmental disaster in recent Brazilian history.
The dam contained waste from the processing of iron ore from mines. After ineffective attempts to contain the disaster, the mudflow reached the Atlantic Ocean after 16 days, where its impact will affect thousands of species of marine fauna and flora through water turbidity and mud sedimentation. including the extinction of species
We give here an example of one of these species, the cnidarian Calvadosia corbini (synonym: Kishinouyea corbini Larson 1980), which is emblematic because it is extremely rare and poorly studied and its known range overlaps with the threatened area on the Brazilian coast.
Calvadosia corbini is a small green and reddish-brown medusa with diffuse pigmentation, it is found in seagrass beds and rock pools and is the only known Atlantic species of Stauromedusae.
Although these tiny benthic stalked jellyfish live in the intertidal zone, they are cryptic and difficult to find, often camouflaged on Sargassum sp.
The medusa feeds on essentially small crustaceans, such as copepods and amphipods (Zagal, 2004), but there is no information on trophic relationships (prey and predators) from Brazil.
Staurozoa populations appear to be highly susceptible to anthropogenic impacts, it remains to be seen whether the small style jellyfish will survive the stress of the sea.
Etymology: Named after Peter Corbin, a marine biologist known for his extensive work on Atlantic stauromedusae
Synonym: Kishinouyea corbini Larson, 1980
