"The blue whale waves its tail before diving down to swim, and this whale waved its tail for us twice yesterday," says Hörður Jónasson who sent these wonderful photographs from a whale watching trip taken yesterday in Skjálfandaflói bay, north Iceland.

Another blue whale was sighted only a few days ago. The species is the world's largest mammal and it measures 30 metres in length and weighs 190 tonnes.
