The authors report an injury caused by a spiny dogfish (Squalus sp) in a professional fisherman that was got hurt in the left hand for a spine in the dorsal fin of the fish and felt excruciating local pain for 6 h and manifested local edema and erythema. The sharks of the Squalus gender, in a similar way to the gender Heterodontus, present two spines in position previous to the dorsal fins, with channels presenting a whitish mass, composed of great and vacuolated cells that produce venom. The Squalus gender has a complex taxonomy, with five nominal species mentioned in Brazil: S. acanthias, S. blainvillei, S. cubensis, S. megalops and S. mitsukurii. The species associated to the injury belongs to the group 'megalops/cubensis'. A detailed study on the taxonomy and toxinology of the Squalus gender in Brazil would be of vital importance in the resolution of those problems and it would serve as subsidy for any other works involving their representatives, besides with aspects of envenoming that this gender can cause and that has rare citations in the literature.
作者报告了一名职业渔民被白斑角鲨（Squalus sp）刺伤的事件。该渔民左手被鱼背鳍上的一根棘刺刺伤，局部剧痛6小时，伴有局部水肿和红斑。角鲨属的鲨鱼与虎鲨属类似，在背鳍前方有两根棘刺，其通道中有白色物质，由大的空泡化细胞组成，这些细胞产生毒液。角鲨属的分类复杂，在巴西提到的有五个标称物种：尖吻角鲨、布氏角鲨、古巴角鲨、大眼角鲨和箕作氏角鲨。与此次受伤相关的物种属于“大眼角鲨/古巴角鲨”组。对巴西角鲨属的分类学和毒素学进行详细研究对于解决这些问题至关重要，除了该属可能导致的中毒方面（在文献中鲜有记载），还可为涉及该属代表物种的任何其他研究提供参考。
