you might not want to think about this but over 3,500 species of cockroaches live on this planet the good news only about 30 of those species have adapted to live around humans the bad news 30 species of cockroaches can live around us roaches are one of the most common pests in the u.s. so it's no surprise that humans are always trying to kill them but no matter how many times we stomp them squash them and bomb them with toxic chemicals these pesky pests always seem to pop up time and time again so what's going on let's take closer look at the roach you probably know better than you'd like Harry Planeta Americana aka the American cockroach but this name is misleading this guy's actually from Africa not America it made its way to the US by infesting boats in the 16th century and it's been spreading to almost every corner in the world ever since turns out it's one of the largest species of cockroach around but that's not the only big thing about it new research has revealed that it has massive genome one of the largest of any studied insect and many of these genes are exactly what makes this roach master survivor let's start with the genes associated with something called chemo reception that's how roaches smell and tastes their environment it turns out they're actually way better at sniffing out and eating food than most other insects the American Roach has hundred and fifty-four olfactory receptors for smell and 544 gustatory receptors for taste more than any other insect on the planet as result these cockroaches are not Viki eaters sure they like cheese meat and sugar like the rest of us but they'll also go for things like cardboard book bindings human toenails rotting meat blood excrete mminton even each other that's right these roaches have been known to eat other dead or crippled cockroaches all in the name of survival it sounds gross but this diverse diet makes it easy to find meal just about anywhere even if it's poisonous to most animals this roach has bunch of genes called cytochrome p450s which help it withstand poisonous chemicals like peppermint these genes code for detoxification enzymes which keep the insects safe on top of that this roach has super strong immune system that seeks out and kills harmful microbes and fungi making the most unsanitary environment look like five-star hotel to the american cockroach not gross enough yet we'll consider this cockroaches can live nearly week without their heads yeah that's not myth they don't have highly pressurized network of blood vessels like humans so they don't bleed out instead their necks actually seal off the opening they can't regenerate whole head but roaches do have an impressive set of regenerative superpowers for up to the first two years of its life the American Roach goes through series of regenerative molt's as it matures into an adult during single molt stage it can replace lost limbs and over series of molt it can regrow on tonight and even its eyes roaches may be hard to kill but there's an easy way to keep them clear of your kitchen cleanliness roach won't just survive in unsanitary conditions it actually enjoys it it's heightened senses mean it actually relishes rotting food so store food in airtight containers cover trash bins and keep your basement dry it might also be smart to plug holes in your walls unused electrical outlets and especially drains since get this roaches can use your plumbing to climb up from sewers into your bathroom sink it might not eliminate the risk entirely but it can't hurt and it will certainly make you feel better however we can't promise it will keep them out of your nightmares
