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. |

(1984) reported a maximum size is 62 cm total length (TL) with size at maturity of 50.5 cm TL (females) and 45 cm TL (males). Size at birth 6.0 cm TL. Oviparous, with eggs in both oviducts in autumn. Feeds on crustaceans, principally Austropandalus grayi and Pseudocorystes sycarius. |
