Abstract

Two tagged-and-recaptured tiger sharks Galeocerdo cuvier, measuring 172 and 304 cm total length (LT) and at age 0·75 and 3·50 years, exhibited unmatched growth rates of 118·4 and 55·5 cm year−1, respectively. The larger fish was nearly mature, indicating that G. cuvier off Brazil could mature considerably earlier than conspecifics from other regions.
