Seems insects, lobsters, fish, birds and primates socially distance themselves whenever any of their brethren catch a disease threatening their well being, something not being done by a significant portion of the population risking possible death while bitching about losing their inherent freedom to be stupid by not social distancing or wearing a mask while spreading said disease to others as seen in the COVID-19 debacle in the good ole USA.
On a shallow reef in the Florida Keys, a young Caribbean spiny lobster returns from a night of foraging for tasty mollusks and enters its narrow den. Lobsters usually share these rocky crevices, and tonight a new one has wandered in. Something about the newcomer is not right, though. Chemicals in its urine smell different. These substances are produced when a lobster is infected with a contagious virus called Panulirus argus virus 1, and the healthy returning lobster seems alarmed. As hard as it is to find a den like this one, protected from predators, the young animal backs out, into open waters and away from the deadly virus.
The lobster’s response to disease—seen in both field and laboratory experiments—is one we have become all too familiar with this year: social distancing. People’s close interactions with family and friends have been cut off to reduce the spread of COVID-19. It has been extremely hard. And many have questioned the necessity. Yet despite how unnatural it may feel to us, social distancing is very much a part of the natural world. In addition to lobsters, animals as diverse as monkeys, fishes, insects and birds detect and distance themselves from sick members of their species.
Any questions?
