Abstract
The diversity of the marine Brazilian Chondrichthyes is focused in historical terms since the beginning of the 20th century, by the analysis of the main publications produced in Brazil and other American countries with respect to the number of species of sharks, rays and chimaeras occurring in this country. In this context, the first volume of the "Manual de Peixes Marinhos do Sudeste do Brasil", published in 1977 by José Lima de Figueiredo, stands out as a landmark in the knowledge about Brazilian Chondrichthyes. This work included 72 chondrichthyan species, and despite its regional restriction to southeastern Brazil, this figure represented a 34% increment in the number of species previously recorded in faunal studies on the Brazilian coast. Containing identification keys, diagnoses and illustrations, the first volume of the "Manual de Peixes Marinhos do Sudeste" became the main reference for the identification of marine chondrichthyans in Brazil. The present paper presents an overview of the conservation status of the group in Brazil, and as an original contribution, an updated record of the diversity of Brazilian marine Chondrichthyes, totaling 12 orders, 36 families, 79 genera and 165 species
