# Book of palm thief - one of the most powerful in the world

Palm thief (or coconut cancer) is a rack-washer living on the islands of the Pacific and Indian Oceans. Palm thieves are characterized by their dimensions: the length of the body is large can reach 40 centimeters without taking into account the claw, and the weight is up to 4 kilograms.

The palm thief is omnivorous - it prefers to eat fruits of tropical trees, but does not circulate with other smaller crustaceans. But here to use the palm thief as food - the task is extremely difficult for large animals. After all, the force with which he can squeeze the opponent to the front pair of his culley is truly huge.

A group of Japanese scientists conducted an experiment with the participation of 29 palm thieves of various floors and weights that live on Okinawa island. In the course of the study, scientists used sensors with a diameter of 5 and 10 mm, capable of measuring a kilogram-force compression.

This is interesting: kilogram-force is measured in Newton (H). 1 kgf = 9, 80665 Newtons (H).

When the sensor was brought to cancer, angry with the fact that it was caught and held in place, he predictably grabbed the device with the front culbs and compressed with all the power.

After analyzing the results of all 29 participants in the experiment, the specialists were surprised by the force of compression of the tongue of palm thief. It was from 29, 4 to 1765, 2 H, while the values ​​increased in proportion to the weight and size of the animal. However, among the caught palm thieves there was not a single copy of over 2, 2 kg. Based on the collected data, scientists were able to calculate the so-called "Palm thief compression force coefficient", which is the same for all animals of this species and is 0, 82.

Taking into account that the palm thief can weigh up to 4 kg, the maximum grind compression force for such a giant was calculated - 3300 N. For comparison, the human bite strength is 750 H, the wolf - 1267 N, and the bear - 1747 N. Palm thief The strength of the bite of most terrestrial animals is superior to the Missisypian alligator, which shows an unimaginable value in 13300 H (PDF).
