Tohorā : the southern right whale / Ned Barraud.

"Once, the mighty tohorā , or southern right whale, was a common sight in winter off the coast of Aotearoa. But it proved to be an easy target for the early whalers, and was soon driven to the edge of extinction. In the twentieth century, however, it became a protected species, and once commercial whaling was virtually stopped, the southern right whale made a comeback. Ned Barraud recounts this moving story in this ... book, a heartening and optimistic tale for every New Zealand child"--Back cover.
