Humpback whales 'bubble-net feeding' in Australian waters has been captured on video for the first time. The drone video was taken at the end of 2020, but researchers have studied the whales' behaviour, confirming they were using the technique.

Bubble-net feeding, where whales deliberately blow bubbles to form a type of net around their prey, has been witnessed mostly in the northern hemisphere. The video was taken off the Sapphire Coast in southern New South Wales

The best way to keep premiums down is to prevent climate change and the disasters it causes

No matter how much you pay for your home or car insurance, if your property is damaged by mouse plague, nuclear radiation, war or rising sea levels you are almost certainly on your own.

If you’re lucky, your insurance might cover you against storms but maybe not against floods (you know the difference, right?). Likewise, your insurance almost certainly doesn’t cover you against storm surges or a dam bursting.

Cevian’s call for more capital to be returned is beyond what most City analysts think possible

An activist investor would have been very useful at Aviva for most of the insurer’s 20-odd years of existence, frustrated shareholders will feel. Outside the banking sector, it’s hard to think of a major UK financial services company that has disappointed its investors so often, or showered such large rewards for failure on its chief executives. The share price is less than half what it was at the time of formation via a three-way merger at the turn of century.

The activist that Aviva has finally attracted is Cevian Capital, which has turned up with an £800m, or 5%, stake just at the moment when Amanda Blanc, chief executive since last July, seems to be the first boss with a decent plan.
