Age and growth of three endemic threatened guitarfishes Pseudobatos horkelii , P. percellens and Zapteryx brevirostris in the western South Atlantic Ocean
Abstract The age and growth of three endemic threatened guitarfish species were analysed using vertebrae of Pseudobatos horkelii , P. percellens and Zapteryx brevirostris . Edge and marginal‐increment analyses were used to evaluate the periodicity of the formation of the band‐pairs, suggesting depos...
