Whale numbers are increasing here, as shown by the increasing traffic levels up and down the east coast coming from and returning to Antarctic waters, and I believe the west coast too. While up north they calve,and then make use of the previously described 'wedding tackle". There are several varieties of whale involved.
Here it is called the southern right whale. Anecdotally said to be so named as being the "right"ie correct,whale to harpoon, but when I searched,that seemed to be BS,elsewhere anyway.
