Let me ask you this. Which one you think has higher intelligence – monkeys/apes or big cats?

You see, and yet there are big cats which hunt monkeys. The ability to hunt is not based on intelligence, but on your senses, speed, mimics etc.

In a preditor prey relationship there is often one preditor and many prey, take for example a coyote and wild rabbits. The rabbits must hide and learn to live in fear of the coyote, but the coyote doesn’t have to be smarter than the rabbits because there are so many, and if it misses one, another will more than likely be close by.

Maybe predators are not necessarily cleverer than their prey, but in most cases they’re larger. Larger size in the prey happens to be case # 6 on the first list ("Ethology") of my bilingual lists of zoological exceptions at excepciones-zoologicas.blogspot.com, where so far only the foreword and the first list can be seen. That case is related to case # 61 on the same list –parasites that are larger than the host– and to one of the weirdest exceptions on the second list ("Morphology"), which is the unique case of the paradoxical frog, whose tadpole is bigger than the adult. Please let me know about any additional examples. The complete set of lists includes nearly a thousand cases and can be useful for students who want to study Biology as a career.

My opinion it is not a matter of which is more intelligent, the knowledge each have is learned by experience and some prey and predator coevolve such as Ringed Seals and Polar Bears.
Also, usually when the predator(s) hunt it seeks out the weakest or slowest: young, old, sick .

True, as I found out years ago. This is exactly the same matter relating to case # 4 on the said first list: "Predators that do not choose as victims (= prey) the weakest individuals".

Yesterday while I was further researching this question found this website which explains prey survival strategies from becoming dinner http://www.nature.com/scitable/knowledge/library/behavior-under-risk-how-animals-avoid-becoming-23646978

My only issue with this article is the statement, I made bold in the quote

which they did not provide any examples or detail explanation

I know of two cases of instinctive (= not learned) reactions to predators: 1) apes go into a panic whenever they see a snake, and 2) certain chicks get scared when they see a long shape passing by above them, advancing along a trajectory that makes a right angle to the length of the shape, because it looks like a big gliding bird, even though they still don’t know about raptorials.

Thanks piscilactovegetarian for replying. It is great to have someone to discuss this subject

My thoughts about instinctive knowledge the "jury is still out". Currently, my hypothesis is that self-preservation induces fear of everything in which the experience, if they survived, determines the knowledge they learned.

Gannet, your concept doesn’t agree with the facts. One can frighten the young of certain bird species by moving above them along a straight line an object shaped like a bird with outstretched wings. Other shapes won’t elicit that reaction. You’re almost like Aristotle rejecting Plato’s notion of the "innate ideas" (built-in ideas, ideas we’re born with) and saying that "there is nothing in the mind that has not previously gone through the senses" (in your case, at least as far as unlearned reactions to predators are concerned [actually, unlearned by the individual but obviously learned by the species and added to the genome]), by which he meant that at birth the mind is a "clean slate", a blank page.

Good Day piscilatovegetarian – I am not rejecting the idea of "innate ideas" I am just challenging the concept. I concur with taxes and reflexes being innate, and that evolutionary adaptation affecting genes which changes a species physiology (which includes the nervous system).

I challenge the concept of the following behaviors being instinctive and provide why I think they are learned:

• antipredation behavior – by observing the reactions of others of its species to the present of something different.
  migration – could be yearlings just following previous generations of their species
  nest building – by observing previous generations building nests
  imprinting – has been claimed by Lorenz as instinctive behavior which based on definition cannot be modified; however, imprinting has been shown to decrease with time.

I believe our conversation has digress away from the OP’s question and I will either piggyback onto either an existing applicable thread or start a new topic on Instinctive Behavior

What if a python eat a human being?

I wouldn’t make a general rule out of it. Except intelligence there are so many other things to consider that such theory as in subject is simply incomplete and unfair. Like someone earlier mentioned the case or rabbits and coyotes. Rabbits needed to learn how to live in one neighborhood with a coyote so I wouldn’t call them less intelligent. Too many variables. Environment, speed, weigh, tricks, condition, weather and so on and so forth.

The difficulty with the concept of innate ideas or innate behaviors is that it is difficult to prove every potential environmental factor did not cause the observed behavior. For example, showing that chicks react to bird-like shapes above them doesn’t prove that another factor did not previously lead to them learning that behavior. Obviously, there are strong cases for innate behavior such as infants pursuing food immediately after birth and juveniles responding with alarm calls at the first time of meeting a predator. I think it is more than likely that animals do have many innate behaviors and ideas but proving that this is the case has proven difficult.

As for the question of predators always being smarter than their prey, I think you’ve already established that that’s not the case. Humans can be prey for large predators, e.g. sharks, crocs and large cats, and I don’t think many people would argue that humans are less intelligent than any of those predators.
