Hair bleaching marking technique in South American sea lions Otaria flavescens: Description and evaluation of method. The aim of this paper is to describe and evaluate the use of the hair discoloration method in South American sea lions, with an emphasis on its advantages and its potential use in future studies. For marking, stamp removable letters and numbers were used, connected to an extensible rod. The bleached marks obtained had a maximum duration of 347 days perfectly visible and, because of the combination of low cost and application simplicity, this technique is considered suitable for both short and long term non-invasive studies in pinnipeds.
