Animal Ethics

The following information was supplied relating to ethical approvals (i.e., approving body and any reference numbers):

Field work involved visual observations and photographic identification and was carried out under Mozambique’s Administração Nacional das Áreas de Conservação permit number 13 for work within the Bazaruto Archipelago National Park.
