Daniel Turpin, a 35-year-old spearfisherman, was killed by a 15-foot shark off Albany, Western Australia, marking the third fatal shark attack in less than a month. Marine experts explain that sharks can detect distressed fish from up to a kilometre away through low-frequency vibrations, making spearfishing particularly risky. Calls are growing for a federal shark research unit to focus on prevention technologies rather than simply tracking and tagging sharks.
