Risk-taking behavior associated with predator inspection has been described in a number of fish species. As a first step in parsing out the contribution of genes and environment to risk-taking behavior, the predator inspection behavior of zebrafish was examined. Predator inspection behavior of seventy males was measured once a day for five consecutive days and their mean daily inspection score — a measure of risk-taking tendencies — was recorded. Zebrafish did not habituate to the presence of a predator and significant individual differences in risk-taking behavior were uncovered. |
