Overview

• The wild dolphin linked to at least 53 biting incidents injuring swimmers from 2022 to 2024 was captured in mid-June and fitted with a dorsal-fin transmitter
• Transmitter signals and public sightings ceased after July 1, leaving its whereabouts unknown for more than six weeks
• A local fisherman discovered the heavily decomposed carcass drifting off the northern Tsuruga Peninsula on August 13
• Advanced decomposition has obscured the time of death, prompting prefectural officials to commission a forensic examination
• Fukui Prefectural Government reported no behavioral change before or after tagging and has not established any causal link between the transmitter and the dolphin’s death
