These beautiful creatures, the largest animal ever to have lived in the history of the world, can grow to 30m (110β€²) and 150–200 tonnes. The babies are born 6–8 metres (25β€²) long and weigh 3 tonnes at birth. Just amazing that even an attempt to visualise that massive size without a comparison (like the common two big buses bumper to bumper) is difficult.

This documentary is American but pleasingly dispenses with the over-the-top drama endemic to Yank docos and sticks to the science. They track some Pacific blue whales down to Costa Rica and discover new things about these animals, which we don’t really know much about.

I really liked this one. Great footage, neatly and adequately explained without dumbing it down, and just beautiful creatures to see. ⭐️⭐️⭐️⭐️⭐️
