As the bible pointed out to Jews, Christians, and Muslems. A Whale ate Jonah, Whilst Orca's haven't eaten anyone.....
Orcas are powerful predators capable of killing prey much larger than humans, such as leopard seals and great white sharks. They have also been recorded preying on usually terrestrial species such as moose swimming between islands.[1] However, wild orcas are not considered a real threat to humans, as there are few documented cases of wild orcas attacking people, and no fatal encounters.[2][3] In captivity, however, there have been several non-fatal and fatal attacks on humans since the 1970s.[4] Experts are divided as to whether the injuries and deaths were accidental or deliberate attempts to cause harm.[5][6]

Seeing as we get so 'heated' on this forum about using any kind of slang term regarding humans, I expect the same PC language requirements will be applied to non human persons.

Especially as they are unable to reply in 'person', and to deny them their inalianable right to reply, is clear discrimination....
I'm sure no Orca would want to be called a 'pikey' or a 'slope', any more than I would want to be called a Ginga, these are all highly offensive phrases to human persons, as such is 'Whale' to non human persons, given it's clear offensive human connotations.....
Given recent actions on Reddit and the BBC that are clearly focused on us all becoming SJW and being fully aware of how we should behave regarding both human and species personal choice, I'm sure the forum will embrace the free will of Orca to be identified as such......
but yeah I think your wife will have a blast if she's into snorkeling!
