Horrible cockroach :o
if a cockroach touches a human being ..
it runs for safety and CLEAN them self ...!!
The name ‘cockroach’ is believed to come from the Spanish cucaracha, with a first noted use in English of cacarootch in 1624.
It true, cockroaches do not need a head to survive. By comparison, and from a purely biological point of view,(a) it breaths through spiracles all over its body. The brain does not control this function. (b) Insects do not have mammalian blood pressure, and would not ‘bleed out’. And (c) as a cold blooded animal a single meal can, if the temperature is cool enough, last a whole month. Other than the danger of infection, a headless cockroach can, in fact, survive for quite some time.
A cockroach can live for a week without its head. Due to their open circulatory system, and the fact that they breathe through little holes in each of their body segments, they are not dependent on the mouth or head to breathe. The roach only dies because without a mouth, it can't drink water and dies of thirst .
There is persistent talk that the cockroach would be the only survivor of a nuclear bomb.

Research shows that the fastest recorded speed of an American Cockroach
is approaching 2.0 miles per hour (75 Centimeters per second). Of
course, it is not going to out race a large animal, but as a relation to
its body size it’s rather fast. In size relative terms, a roach about
the size of a cheetah would move at about 50 MPH – only slightly slower
than that majestic hunter. A part of their speed is attributed to the
excellent ‘communication’ from eyes and antennae to their legs.
