•Moving from acute (4d) to subacute (14d) to chronic (50d) nano-CuO exposure times increase Xenopus mortality.•NanoCuO subacute LC50s are below LOECs for Xenopus.•At low concentrations nano-CuO has marginally beneficial effects on Xenopus growth and development.•At 0.3mgL−1, less than 40% of tadpole...
