TOHORĀ { 27 images } Created 8 Nov 2020
Our Whales Are Back - Last century, southern right whales were hunted until there were none left—none that we could find. A small group of these whales, also called tohorā, hid from the harpoon. Deep in the subantarctic, the survivors birthed and nursed their young. Now, tohorā are returning to the coasts of New Zealand to shelter over winter. Are we ready for them?

![As soon as tohorā calves are big enough to handle the rigours of the open sea, their mothers will lead them on their first migration. The calves grow about a metre a month, the mum has very fat-rich milk, so that means that the calf is able to cope with the migration, but also cold temperatures. For female tohorā, having a baby is a significant undertaking. “They’ll have one calf every three years, and [the mother] will lose up to 25 per cent of her size investing in that calf,” says Carroll. “So if they don’t get enough kai, they can’t actually gestate or look after that calf. “That’s why it’s important to understand where our whales are feeding, so that we can understand how climate change will impact their recovery.”<br />
