The question was more intelligent that us in applied mathematics and critical thinking. Dolphins, whales, orcas have all been well studied. And while they are in the top 0.01% of intelligent life on earth. They are on average not smarter than humans. Though I can not speak for the below average humans.







The past 30 years of studies conducted on them.
All of the things you’ve highlighted, except speaking to dolphins, are things primates also do.
The very specific topic for this post, were applied mathematics and critical thinking. And no, orcas do not show any advanced application of mathematics.
If you know of a study that indicates their understanding and application of mathematics rivals ours. Please link it.
