We aimed to evaluate the promotion of the welfare of invertebrates used in research through their representation in the scientific community, the dissemination of research and inclusion in ethical debates. The analysis resulted in the predominance of biological, utilitarian approa-ches in animals of medical and economic interest, whose incipience of information on the con-ditions of collecting, manipulation, and experimentation compromise the reproducibility and development of the area. It is discussed the inclusion of the invertebrates in the ethics deba-tes, whose claim for standards and protection, demands the exploitation of the researcher in search of technical and ethical excellence in the planning, execution and dissemination of his research to strengthen the social and scientific contract generator of benefits to science and to the animal's quality of life
