A single lonely and possibly sexually frustrated bottlenose dolphin has been blamed for a series of attacks on swimmers in Japan's Fukui Prefecture, particularly in the towns of Tsuruga and Mihama. The dolphin, identified by unique fin markings, has injured over 45 people since 2022, with 18 attacks occurring since July 2024 alone. Experts, including Tadamichi Morisaka from Mie University, suggest that the dolphin's aggressive behavior might be due to its isolation from its pod and natural mating behaviors being misdirected towards humans. The dolphin's actions, ranging from biting to humping, are generally not intended to harm but rather to seek interaction or display sexual frustration. Local authorities have increased lifeguard patrols and implemented measures such as reduced swimming hours and sonic deterrents to protect beachgoers. Despite the non-lethal nature of most injuries, the situation remains concerning due to the potential for more severe incidents.
