Justification
Sympterygia lima is a shallow water (30 to 60 m) fanskate endemic to Chile. Maximum size is 62 cm total length (TL). There is only little information available on its biology. It is captured as bycatch in the bottom trawl fisheries of Valdivia, but specific catch data are unavailable. Its narrow depth distribution in shallow water makes this species potentially vulnerable to overexploitation. Insufficient information available to assess the species beyond Data Deficient at present.
