Threat test The threat stimulus consisted of the experimenter touching the squid with a prod on its arms, up to 10 times or until it retreated. Five behaviours were measured: - number of touches before retreat - first response (a categorical variable) - frequency of jetting - number of times the prod was grabbed - frequency of arm flower postures 2.

Brief description

Behavioural syndromes are important in the context of understanding the evolution of behaviour. This study examines the lifetime development of shy/bold behaviour of dumpling squid (Euprymna tasmanica). The first component examined correlations of shy/bold behaviour across two test contexts - a threat and a feeding test, measured 5 times during the lifetime of the squid. The second component examined developmental plasticity in shy/bold phenotypes with age and sexual maturity.

Purpose
To describe the development of shy/bold behaviour of dumpling squid (Euprymna tasmanica) across their lifetime. Within this, the aims were to examine correlations of shy/bold behaviour across different functional contexts, and to examine whether shy/bold phenotypes showed (relative) developmental plasticity in response to age and sexual maturity.
