Of interest to some? Whale viruses

Whale breath collected by drones is giving clues to the health of wild humpbacks and other whales.

Scientists flew drones equipped with special kit through the exhaled droplets, or "blows", made when the giants come up to breathe through their blowholes.

They detected a highly infectious virus linked to mass strandings of whales and dolphins worldwide.

The sampling of whale "blow" is a "game-changer" for the health and well-being of whales, said Prof Terry Dawson of King's College London...

Very Interesting.

an aside - 

My view of strandings,  in cases where they're all very sick, or all had their ear drums blown out by sonar or some other large-group malady, is that they are 'returning to land' as a species instinctual behaviour.

You know, much like a new born human baby will grasp a finger quite strongly, which is thought to be an instinctual behaviour left over from when we hung around in trees..

Perhaps in evolution, where the proto-whales could still exit the water in the face of overwhelming danger, such a behaviour had it's benefits.
