This dataset comprises the first three years of monitoring (September 2015 to August 2018) along the central-south São Paulo state coastline, from 24°1'1.248\" S 46°23'52.026\" W to 24°26'49.147\" S 47°4'49.505\" W. During this period, 3790 animals of 47 species were recorded, 94.88% of which were dead and 5.12% alive when first observed.
