Wikie is a 14-year-old whale living in captivity in France.

Wikie is an orca. Orcas are extremely smart, making them dangerous to their prey. Orcas are also called "killer whales."

Their intelligence makes them easy for humans to train. Many captive orcas perform tricks for audiences at marine parks. And, as it turns out, orcas can even be trained to "speak" using human language.

An group of international researchers said this week they taught Wikie to repeat human words.

They taught her to mimic words like "hello," "bye bye" and the name "Amy." She also repeated numbers as well as sounds made by the researchers.

Wikie was a quick learner; she was able to mimic a word or sound after just 10 tries.

The news made Wikie a trending topic on social media.

In the wild, orcas live in groups of whales called pods. Each pod uses different sounds and calls to communicate with each other.

Scientists already knew that orcas were able to learn new whale "dialects." One orca even learned to communicate with a dolphin while living with it in captivity.

Although Wikie is able to mimic human words and sounds, that does not mean she can understand them.

Josep Call is a professor of evolutionary origins of mind at the University of St. Andrews in Scotland. He is the co-author of the study. He told The Guardian this week that there is no evidence that Wikie understands what ‘hello' stands for.

But the orca's ability is, in Call's words, "impressive -- even though the morphology [of orcas] is so different, they can still produce a sound that comes close to what another species, in this case us, can produce."

The study was published in the journal Royal Society B: Biological Sciences.
