capture stree

Yes, "capture stress" does indeed mean "stress caused by being captured". But "stress" in this context doesn't just mean a "feeling"; it means physical and physiological stress. "Stress" is often used when there is no psychological aspect; for example, an engineer would speak of the stress a bridge suffers in a high wind.

physical and physiological stress? psychological aspect? a bridge? a high wind? Not sure what they are.

Hi? Still not get it.

He means the stress suffered by the shark is of the nature of a serious physical (of the body) response one which can kill it. Think of the medical definition of "shock".


He is saying that they are not speaking of the shark's emotional reactions, but of dangerous changes in the shark's body. If the shark had emotional reactions to what the biologists did, these would be the "psychological aspects">


The word "stress" is commonly used to denote the emotional AND bodily reactions - but it more properly describes those which are of the subjects physical body.

Syntinen points out that physical structures like bridges can be said to suffer stress, such as when there is a high wind - and the bridge's structure is subject to unusual loads.

We do not know if the shark experiences an emotional reaction to capture - but we DO know that it experiences a physical one.


Oh - a "high wind" is a very strong one.

Yes, you make it clear.
