Samuel Gruber, a researcher at the BiminiBiological Field Station in the Bahamas, said orcas coulddevelop and spread new such hunting tricks. “Their learningabilities are so great, that if one of them happened to” flip overand stun a shark, “and see that sharks freeze up in this state, theycould communicate it to the other ones.” (Adapted fromNewsweek, May 10, 2017)
