We present this blog with the intention to serve as a journal about the life on our planet. While we are not (yet) experts in the field, our enthusiasm and interest on the different lifeforms around this world came to provide texts and comments on new and relictic subjects. This blog came from the idea of entereing the blogroll of science writting and reviving our past sites in the subject, all in Portuguese language: BioData by Rafael and Biolista by Piter. The blog will serve as a sibling to our other existing journal, Poisor Tristesi, as well for discussing the representation of both extinct and extant life in art.
