About 30 whales within the unique stranding have been moved from the sandbars to open ocean on Tuesday, however a number of acquired stranded once more.

Why the whales ran aground is a thriller. The pod might have been drawn into the coast to feed or by the misadventure of 1 or two whales, which led to the remainder of the pod following, Carlyon mentioned.
“It’s actually possible this was the one stranding occasion of a giant group. This could have been one huge group offshore,” he mentioned.
Marine scientist Vanessa Pirotta mentioned there have been numerous potential the explanation why whales would possibly change into beached, together with navigational errors.
“They do have a really sturdy social system, these animals are intently bonded and that’s why we have now seen so many on this case sadly on this state of affairs,” Pirotta mentioned.
And rescuing them doesn’t at all times work “as a result of they’re desirous to return again to the pod, they may hear the acoustics for the vocalizations of the sounds that the others are making, or they’re simply disoriented and on this case extraordinarily careworn, and simply in all probability so fatigued that they in some instances don’t know the place they’re,” she added.
