For How Long Can A Cockroach Live Without Its Head?

Cockroaches can infact live up to a few weeks without their head.
They are able to do so because they do not have blood pressure or one central nervous system like humans (or even other animals for that matter)
they have a series of ganglia (or nerves) spread through out their body, enabling the body to function without the head or brain.
Also the neck automatically closes up at the point of decapitation acting like a blood clot so they do not bleed to death (like humans would)
the headless roach can move around and do simple tasks but will eventually starve to death
whats even weirder, is if the head was chopped off cleanly, the head itself can survive too! It can sit there and move its antennae until it eventually "runs out of steam"

They can live without a head for two weeks because their natural organs harden over and heal for a period of two weeks before loss of blood and tissue damage kill it.

There are approximately three thousand five hundred different species of cockroaches, falling into six different families. The most well-known cockroaches are the American cockroach, the German coackroach and the Asian cockroach. The cockroach has made Earth its' home for millions of years with the earliest cockroach fossils dating back as far as three hundred and fifty-four to two hundred and ninety-five million years ago, during the Carboniferous period. It is sometimes said that the cockroach will "inherit the earth", after humanity destroys itself, as cockroaches are able to withstand many 'situations'. A cockroach is able to hold its' breath for fouty-five minutes, it can go without food for up to a month and it has the ability to slow down its' heart rate. Cockroaches also have a higher risistance to radiation, up to six to fifteen times higher than that of mans. Amazingly, a cockroach can even live without its' head. A cockroach will continue to scurry around, headless, for up to one week.
