First northernmost record with 2 individuals observed (1 photographed) from Chipehua Bay, Gulf of Tehuantepec. Fishermen in the Gulf group all species of guitarfish common in the area (e.g. Rhinobatos leucorhynchus and R. glaucostigma) which represented 48% of all rays captured (observations obtained from the sampling of sharks and rays between September 2004 and
August 2006). Fishermen reported that Gorgona guitarfish is uncommon in the area, so it is possible that the frequency of occurrence of R. prahli may be low, with only occasional captures (Ref. 101827).
