While killer whales are powerful animals, they are generally not considered to be aggressive towards humans. In captivity, trainers and orcas have a close relationship built on mutual trust and respect.
However, it is important to note:
* Incidents have occurred where orcas have displayed aggressive behavior towards trainers, but these incidents were usually related to specific situations or individual animals, and not indicative of a general threat.
* Orcas are wild animals, and unpredictable behavior can occur.
* There have been reports of orcas attacking humans in the wild, but these are rare occurrences.
It's crucial to distinguish between factual information and sensationalized accounts that might be circulating online.
