They every are available in a distributed of flashy bright colors, doubtless meant to warn predators of the neurotoxins within the frogs' skin.As a group, Brachycephalus, are famed to inhabit the cloud forests of southern Brazil since the Eighteen Eighties.The first species of Brachycephalus was delineate in 1842 by the celebrated German naturalist Johann Baptist von Spix, however most species within the genus are discovered solely within the past decade.Expecting that a lot of of those frogs slumber in the southern a part of the Atlantic Forest, researchers crystal rectifier by Marcio Pie of the Universidade Federal do Paraná visited the woodland within the states of river and Santa Catarina.Over the course of 5 years of munition, the team of researchers has provided the most important addition to the famed diversity of Brachycephalus, with seven new species.'Although about to several of the sphere sites is exhausting, there was invariably the sensation of anticipation and curiosity concerning what new species might look like', aforementioned prof Pie.What's exceptional isn't simply their little size, however conjointly their gorgeous markings.The new Brachycephalus mariaeterezae, for instance, is bright orange with blue splotches on its backbone.Brachycephalus olivaceus could be a greenish-brown, whereas Brachycephalus auroguttatus contains a bright-yellow head a color that fades to brown on its limbs.
