Whales and orcas were carrying viruses no one knew existed

Researchers studying Caribbean whales and orcas have discovered two new viruses not previously observed in these animals. The viruses were found using advanced genetic sequencing of archived samples, revealing a previously invisible layer of marine life. Their genetic makeup suggests these viruses may have ancient roots in whale evolution. What they mean for whale health is still a mystery, but the discovery opens the door to many new questions.
