98/150: Cockroaches, the probable survivors of an apocalyptic future

Animalia: Arthropoda: Insecta: Blattodea: Ectobiidae: Parcoblatta: Parcoblatta pennsylvanica (De Geer, 1773)

Cockroaches are one of the most adapted and ancient group of animals still in existence today. They are found on every continent except Antarctica and can survive being decapitated, being submerged in water and high levels of radiation, thanks to their open circulatory system. Cockroaches have been observed surviving 10,000 radon units of radiation, which is equivalent to the Hiroshima atomic bomb. This is attributed to the slow level of cellular division in cockroaches, since radiation specially targets dividing cells.  While cockroaches may excite the ‘eww” factor for many people, cockroaches are one of the most intelligent insect group studied, exhibiting social learning, group decision making, and a surprising ability to self- medicate. When a group of cockroaches being studied were infected with a parasite, the cockroaches migrated to colder habitats to slow down the parasite’s development. So, while you may not be a fan of the cockroaches in your kitchen, one must still appreciate the wonderful adaptability of these little critters. #Canada150 #Biodiversity150
