Animals often enough render each other the various help: for example, primacies are engaged грумингом (try to discover each other parasites) or nurse another's cubs. However cases of rescue of colleagues from a trouble meet in fauna extremely seldom.

The international collective of scientists has made the following experiment: researchers have simulated a situation when ant Cataglyphis cursor appears обездвижен because of a sand collapse. However researchers not simply присыпали an insect sand, but also have fixed it by means of a nylon trap.

On a gain got to a trouble relatives have rushed: one dug out a victim, others pulled it for pads. But it proceeded only until they have not found out the nylon thread keeping an ant. As soon as the trap has been found, insects перегрызли a thread, and the relative has appeared on freedom.

The subsequent experiments have shown that Cataglyphis cursor come to the rescue only to the fellow tribesmen, but do not try to rescue ants of other kinds or other insects.
