According to one study in Suriname, piranha attacks tend to peak in the dry season when food is relatively scarce and the water levels are lower, leading to heavier than usual concentrations of fish in the water. Fatal attacks tend to be rare, and most attacks take the form of individual nips and bites to extremities such as the feet and hands. Splashing tends to make piranhas more likely to attack, and children are often attacked for this reason.\r \r Various myths exist about piranhas, such as how they can dilacerate a human body or cattle in seconds. These refer specifically to the red-bellied piranha. A recurrent story is that they can be attred by blood and are exclusively carnivores. A Brazilian tale called piranha cattle states that they sweep the rivers at high speed and attack the first of the cattle entering the water, allowing the rest of the group to traverse the river. A study in Suriname found that piranhas may occasionally attack humans, particularly when water levels are low.\r \r In the city of Palmas, Tocantins, 190 piranha attacks were reported in the first half of 2007. On 25 December new, 70 bathers were attacked in Argentina.\r \r Subscribe for more full documentaries on Unusual Wildlife Animal and Nature.
