I always think it’s a bit odd when scientists discover that animals have personality — something that most people who spend time around animals can tell you right off the bat. But, I suppose what they really mean is that scientists are quantifying personality, which is a bit different.

This article discusses a new study on guppies (yes, the small and admittedly rather silly-looking fish) and how much personality they have. It’s a lot, apparently, at least in regards to risk taking. Some fish would clearly be out riding motorcycles if they could, while others wish they had been given the opposable thumbs necessary to start a knitting club. It’s neat reading about the ways in which scientists are developing personality tests for animals, even if it’s been clear for a long time that yes, your cats Chocolate and Marshmallow really are completely different in every way possible.
