ResumoThe colubrid snake Echinanthera affinis occurs in the Brazilian Atlantic Forest, from Bahia (roughly 14 o S) to Rio Grande do Sul (roughly 30 o S) (Di-Bernardo 1992, Argôlo 1998).This small snake is known to feed upon anurans and lizards (Marques et al. 2001).Here we report on an unexpected gut content of an individual collected in the wild.An adult female E. affinis (509 mm SVL, 132 mm tail length) was found moving by day on the ground within a secondary forest at the Parque Estadual das Fontes do Ipiranga, São Paulo (23º 39'S and 46º 37'W), on 7 October 2002.After its dissection, an individual of Amphisbaena mertensi (about 260 mm SVL, 22 mm tail length) was found in its stomach, ingested headfirst.The snake (and its prey) is housed in the collection of the Instituto Butantan (IB 69610).Amphisbaenians have fossorial habits and generally are able to inflict powerful bite (Gorzula et al. 1977) and rotate the body vigorously (OAVM pers.obs.), two defensive tactics that cause these reptiles to be preyed on Do aglyphous colubrid snakes prey on live amphisbaenids able to bite?
