A humble group of African ticks set a new record for their species surviving 27 years in a laboratory. Eight of those years the tick spent without any food, according to a recent study published in December in the Journal of Medical Entomology.The tick studied was an Argas brumpti Neumann, a large soft tick that typically inhabits drier areas of eastern and southern Africa, according to the study authors."The longevity of these ticks is apparently a record for any species of tick.
The delay in reproduction likely represents long-term storage of viable sperm, also apparently a record for any species of tick," researchers wrote.
Scientists put six adult females and four adult males in a setting where researchers were absolutely baffled the bugs lasted as long as they did.
