Blue whales, the world’s largest mammals, are returning to Spain’s Atlantic coast after an absence of more than four decades, Guardian reports.
The first one, according to the report was
spotted off the coast of Galicia in north-west Spain in 2017 by Bruno Díaz, a
marine biologist who is head of the Bottlenose Dolphin Research Institute in O
Grove, Galicia.
The report states further that another was spotted in 2018, and another the following year, and then in 2020 they both returned. Just over a week ago a different specimen was sited off the Islas Cíes, near O Grove.
