Abstract

ESTEVES, Juan et al. First record of the interaction between Isistius sp. (Elasmobranchii: Dalatiidae) and Balaenoptera physalus (Mysticeti: Balaenopteridae) in Venezuelan waters. Bol. Invest. Mar. Cost. [online]. 2018, vol.47, n.1, pp.143-149. ISSN 0122-9761.  https://doi.org/10.25268/bimc.invemar.2018.47.1.742.

The stranding of an adult male Blalaenoptera Physalus (Mysticeti: Balaenopteridae) in Los Cocoteros Beach in Margarita Island, Venezuela, gave the chance of studying the interactions present in it. 33 injuriess were found in several points of rorqual tegument; oval or rounded in shape, like craters, from 5 to 7 cm long, 5 to 6 cm wide, and 3 to 5 cm deep. Most of them, were fresh. Wounds were attributed to the cookie cutter shark Isistius sp. (Elasmobranchii: Dalatiidae), given the remarkable correspondences. The present note constitutes the first known association between the cookie cutter shark and the fin whale in Venezuelan, Caribbean and western Atlantic waters.

Keywords : Cookie Cutter Shark; Fin Whale; Bitemarks.
