Do orcas still exist?

Good day, I'm curious to inquire about a fascinating topic. As someone who is avidly interested in marine life and conservation efforts, I'm compelled to ask: Do orcas, also known as killer whales, still exist in our oceans today? I've heard about their impressive hunting abilities and social structures, but with the myriad of environmental threats facing marine ecosystems, I'm keen to know if these majestic creatures continue to thrive or if their populations are facing decline. Thank you for your attention to this inquiry.
