More dolphins found on east Japan shores a day after 33 beached

They should check their stomach contents for masks and microplastics.

What caused the whales to beach this time? 

Was it because the whales lost their sense of direction and got exhausted by straying into the cold current that flows near the coastal areas, as some scientist assumes?

The mass beaching of melon-headed whales, numbering 150, occurred in Ibaraki Prefecture, in 2015; the largest ever stranding occurred in February 2017, in Australia, resulting in 250 deaths, ; another mass beaching of 145 pilot whales occurred in New Zealand in 2018. Then, 500 pilot whales were stranded in Australia in September, 2020. More than two dozen whales died in a mass stranding at a New Zealand in March last year.

And this incidence. Doesn't such mass stranding of whales occur way too often?

Aren't the causes the sonars submarines discharge, what country they belong to I don't know, rather than parasites, epidemics or the cold currents? I really want to know the answer.

Poor dolphins, they were probably trying to get away from all the plastic garbage!

fukushima water...

Indigo, I so hope you're wrong.

Dolphins have a pretty similar body temperature to humans. The water was pretty warm last week which could have lured them up here, and the temperature drop could have been a bit tough on them.

A lot of internet marine biologists making up scenarios. They seem to neglect the fact that mass whale and dolphin beachings have been going on for thousands of years. Long before sonar, climate change and the Fukushima disaster.

In the past it has been parasites/ worms in the air sinus and inner ears that were identified as being linked to disorientation in stranded dolphins. Research from 1970-1976, published in 1978- The Journal of Parasitology

Nice to see the people actually trying to help the dolphins. Thank you lovely people of Chiba prefecture

I wonder how dolphins navigate. It is known that geese navigate by feedback to the brain from magnetic elements in their nervous system, so if the whales have that too, the eastward wandering of the magnetic North Pole could cause faulty navigation, though the Pole's directional change would suggest it would more likely take them further out to sea, but then we don't know exactly how it's used by wildlife.

Sonar!!!

Sonar!!!

There was a sub hunting excercise involving SK, JP & US recently. I'm with sonar theory too, or at least sone kind of underwater electronic signal.

In view of the fact that China and an anti-China block are fiercely competing with each other to develop superior submarines, one cannot deny the possibility that submarine sonars are the culprits of the mass stranding of these sea mammals.

Dolphins are suppose to be the smartest ocean creatures due to brain size almost as large as humans. However, we know too little about them and of course if humans are disturbing their eco-location system then that could have dangerous effect. Thanks to "vocieofokinawa" for all of the resent info I had no idea about that has been happening. The huge crowd funding aquariums need to be shut down and instead should have real research of our oceans that cover 70% of our beautiful planet. We still know so little about the oceans and only the companies trying to drill for oil and gas are the ones doing any studies for their own personal gain. As a people, we are only concerned these days by our stupid social media feed and how many likes we can get instead of really caring about each other and our oceans.

Masks, nanoplastics, radiation or sonar. Take your pick.

Nobody seems to have any real idea of why the dolphins were beached. Some say the pre-production of the offshore wind turbines off Isumi messed with their natural navigation.
