The tail of a southern right whale, off the coast of South Africa
A southern right whale's head measures one third of its total length. It is easy to identify, as the enormous head is covered in white-coloured outgrowths of tough skin. They are only found in the oceans of the southern hemisphere.
一條南露脊鯨的頭部長為其整個身體的三分之一。這類鯨魚非常容易識別，因為巨大的頭部被一堆白色的硬糙皮覆蓋。人們只能在南半球的海洋里看到南露脊鯨。
