Orcs reveals similar personality traits to humans and chimpanzees, such as play, joy and affection, according to a new study published today by the American Psychological Association (AAP).
Researchers in Spain analyzed the personality traits of 24 orcas captured in the United States and the canaries – six were caught in nature, while the rest were already captive – and used questionnaires filled by other trainers and officials who worked closely with animals to classify any orca studied in a list of 38 personality traits , Including acting, independence, tenacity, courage, sensitivity and productivity.
These characteristics have been analyzed in comparison to previous studies on the same personality traits in chimpanzees and humans, according to the AAP report on the study, published today in the journal Journal of Comparative Psychology.
"This is the first study to examine the personality characteristics of orkens and how they relate to humans and other primates," said author Ulan Ovda, a doctoral student at the University of Girona, Spain.
"These similar personality traits may have been developed because they were necessary to create the complex social interactions in popular groups that we see in orcs, humans, and other primates," he said.
The study uses a common personality marker called the Five Factor Model – Extroversia, Awareness, Kindness, Dominance and Treatment.
The model, developed in the 1930s, describes personality traits through a combination of adjectives or descriptive phrases.
The researchers found that some of the orca's personality traits were similar to those of humans and chimpanzees.
"Orcs were like humans and chimpanzees in the extraversion factor (joking, excited, and social)," the statement said.
Orcs and chimpanzees also share a combination of personality traits in consciousness (permanence, tenacity and productivity) and grace (patience, reconciliation, and non-distribution), along with some characteristics associated with dominance.
According to the AAP, the findings may indicate convergent evolution in which the personality characteristics of orcs and monkeys are similar due to the advanced cognitive abilities required for complex social interactions.
Orcs can live up to the age of 90 in hunting groups together and share food, demonstrating advanced communication and coordination skills.
These features received international news coverage when Orca aged 20 known as J-35 or Tahlequah began pushing the dead dead baby in July off the coast of Vancouver Island, Canada.
With the help of the rest of the tribe, he kept the dead kitten floating for 17 days, swimming for hundreds of miles in an exhausting effort that interfered with the group's ability to hunt.
