Extant animals size

[Catherine]

Quote:In June 2015, scientists flying over southern Chile counted 337 dead sei whales, in what is regarded as the largest mass beaching ever documented. The cause of the mass deaths is not known, however toxic algae blooms caused by unprecedented warming in the Pacific Ocean, known as the Blob, may be implicated.

 
This is an unbearable loss. The species is so endangered. Losing Sei Whales after they have made such a comeback is unbearable.
I wish we could find out why whales around the world are beaching themselves. I am sure it is something we are doing wrong.
