They may be unwanted pests in your home, but perhaps once you learn that cockroaches show signs of having distinct personalities, you'll think twice about pulling out that shoe.
Researchers at the Université libre de Bruxelles in Belgium set out to study the behavior of these creepy crawlers. They studied American cockroaches by placing radio tags on each one. They then placed the insects into an enclosed dark setting so that they could track their movements, according to an article in Mother Nature Network. After observing the cockroaches for a week, the scientists began to notice distinct personality types. In their research, they described the two groups as "bold or explorers" while the others were "shy or cautious."
Isaac Planas Sitjà, a researcher from the university, told Mother Nature network, "Shy individuals are those that spend more time sheltered and explore less the arena or the surroundings. Instead, bold individuals are those that spend most part of the time exploring the surroundings and spend less time sheltered."
What do these two personality types mean for the longevity of the seemingly indestructible cockroach? Bolder cockroaches are more likely to go out in search of food - a risk that makes them more susceptible to predators. The more cautious cockroaches are more likely to stay hidden, which if crumbs or other food sources are scarce, they may not flourish. However, having two distinct types will ensure that at least part of the population survives.
