killer whales kill whales, eat their tongues and leave rest to rot.

Does that count Mr O?

Chris,

Might be that whale bodies are a totem for the killer whale clan. Or whale tongue might be a delicacy to killer whales - do they eat it with caviar?

But one thing for sure: I'm damn glad not to have been born a krill.

not sure about caviar, but they are smart so may well do.

if a killer whale enters an area with white pointers, the latter will try and flee.

the killer whales simply charge them fom below and turn white pointers upside down, when they become rather useless.

here is more on the fear of the poor white pointers.

Chris,

I'm petrified of killer whales. And if I'm afraid then I bet those white pointer sharks must be shaking in their boots!

Misop,

Only those killer whales in the Caspian Sea.

They do not operate solely by programmed behaviour or instinct. The difference between humans and other animals is a difference in degree not in kind. A smaller proportion of human behaviour may be based on instinct than the behaviour of other animals but the difference is of degree not kind. I think all animals including humans have both instinctive and sentient behaviour. I have three children. The behaviour that led me to have three children is basically the same which leads the male fox to engage with the female fox to produce cubs. We are programmed to do it.

Evolution works by small changes. Animals have developed which depend to a greater degree on sentience or conscious behaviour than other animals. However, it is likely that the behaviour of all animals including humans is a combination of instinct and sentience.
