Horrific Observations Confirm That Orcas Feed on Blue Whales.

Confirm? I remember reading a book during the 1980s (that could have been written much earlier) that discussed orcas killing and feeding on blue whales.

That makes me wonder how much science is just a repeat of knowledge we already once possessed and have forgotten. There are millions of books written yearly, and as many papers if not more. I bet there’s so much in there lost and then rediscovered.
