I was watching the thoroughly engaging Stephen Fry and his new series Last Chance to See earlier this week. It's a series where he and naturalist Mark Carwardine go in search of endangered species - following in the path of Carwadine and Douglas Adams's similar expedition from 20 years earlier. It's well worth watching.
I flicked on to the programme just as Fry and Carwardine arrive in Baja to go in search of blue whales - a creature still on the endangered list, a list first compiled in 1948...sheesh, what are we humans like. With the help of a friend in old Cessna 182 they eventually found a couple of blue whales, one of them fluking - where the massive tail is raised clear of the water. It was a magnicent spectacle and I couldn't be quite sure whether I enjoyed the footage from the boat or the Cessna more.
Before they found the blue whale though, there were dolphins and humpback whales and all of them were jumping or breaching or fluking and I thought....
... isn't it funny how even sea-mammals seem to want to fly :-)
