泰晤士河中发现了鲨鱼

London’s River Thames was declared “biologically dead” in 1957 due to high levels of pollution. Sixty-four years later, it is a thriving ecosystem of more than 115 species of fish and 92 species of bird. Three species of shark were detected in the river as the Zoological Society of London prepared its most recent State of the Thames report.
