Watch: BBC follows operation to rescue shark stranded in South Korean canal
- Published48 minutes ago
As soon as a large shark was spotted in a canal in Busan - a bustling shipping hub and beach city on South Korea's south-eastern tip - marine biologist Kim Hyun-woo was drafted in to rescue it.
He got the call in mid-September, on his way home from a business trip tracking shoals of mackerel to aid fishing vessels. Despite being one of the country's leading shark experts, he never thought he'd be asked by the coastguard to actually save one.
