On 21 August 2020, two different social units were recorded in this area with an estimate of 21 individuals in total (12 in the first and nine in the second). The Mediterranean sperm whale subpopulation is considered Endangered under the IUCN Red List and an understanding of its movements and social structure is lacking. These observations increase our knowledge on its conservation biology and possible threats.</p> Davide Ascheri Elena Fontanesi Copyright (c) 2023 Davide Ascheri, Elena Fontanesi https://creativecommons.org/licenses/by-nc/4.0 2023-02-21 2023-02-21 24 1 1 5 10.47536/jcrm.v24i1.352 https://journal-iwc-live.netxtra.dev/index.php/jcrm/article/view/367 <p>This note reports an unusual observation of a mother and calf pair of southern right whales on 27 July 2021 off the coast of Ilhéus, Bahia state, northeastern Brazil. The sighting was made from a 29ft cruiser boat (brand Cabrasmar), with a 225HP inboard engine, during a whale watching tour in a humpback whale (<em>Megaptera novaeangliae</em>) breeding area.</p> Thomas Foucart Alice De Moura Lima Copyright (c) 2023 Thomas Foucart, Alice De Moura Lima https://creativecommons.org/licenses/by-nc/4.0 2023-02-21 2023-02-21 24 1 7 11
