"Jumping Spiders: The Adorable Memory Masters of Recognition"

Adorable jumping spiders, typically considered asocial, have been found to recognize and remember each other. In a study on Phidippus regius, researchers observed that the spiders behaved differently towards spiders they had previously encountered compared to strangers. This individual recognition is typically associated with social animals, but the jumping spiders exhibited long-term social memory, suggesting they are capable of individual recognition. This finding adds to the growing list of surprising traits exhibited by jumping spiders, including biological motion perception and REM-like sleep behavior.
