So I've rewritten this as The 5 F's:

Fight - fight back (need to feel strong enough, or be cornered)

Flight - run away (need to know you have escape route and can run fast enough)

Freeze - stay still, try not to be 'seen' - try to hide in plain sight (need to know you can do this and not be seen, but this can also be a panic response when cornered and no other options present themselves)

Fawn - appease your hunter, play along (requires guile and some confidence/skill)

Feign (death) - pretend to be a corpse, this may be a final tactic to having been seen/caught (eg after freezing, flighting, flying etc haven't worked) - you are trying to feign not being a target or a threat by 'going limp' (only works if the hunter doesn't like to scavenge or play with their food)

but I wonder if there is also a 6th one? (or even 7?)

Fantasize - retreat inwards to a safe(r) imaginary place (this may arguably be an alternative version of flight)

- Fragment may be an extreme form of this, break into imaginary parts to make more of 'you'; safety in numbers
