Personality traits in southern dumpling squid (Euprymna tasmanica)

This study examined the relationship between personality traits and a number of biological traits in the southern dumpling squid, Euprymna tasmanica. There were 2 contexts in which traits were measured - domain-general or context-specific manner, and four personality traits were measured (shy avoidance-bold aggression, activity, bury persistence and reactivity). Trait expression was context specific, and trait variation was partially explained by maturity and size, but had no links to gender or somatic/reproductive condition.
