J. Ingles and D. Pauly presented at the Fourth International Coral Reef Symposium a seasonally oscillating growth curve for the puffer Sphoeroides testudineus (Tetraodontidae), based on length-frequency data collected in 1974 in Florida by T.E. Targett, but forgot to include the corresponding growth parameters in the ensuing publication. These are given here (TL8=30, K=0.51 year -1, C=0.7, and WP=0.05), along with some related biological information on the species.
