Reactive oxygen species (ROS) levels in the body wall of sea cucumber following exposure to elevated temperature (26 °C, light-blue filled square), water-accommodated fractions (WAF) of Oman crude oil at an optimal temperature of 16 °C (WAF + 16 °C, light-red filled up-triangle), and Oman crude oil WAF at an elevated temperature of 26 °C (WAF + 26 °C, light-yellow filled down-triangle). The Control was the sea cucumber exposed to pre-filtered natural seawater only at an optimal temperature of 16 °C (light-green filled circle). Error bars represent 95% confidence intervals. Asterisks (**, or ***) denote the significant differences between the treatments and the Control (p < 0.01, or 0.001, respectively). Dark traits denote the significant differences among the treatments (two-way analysis of variance (ANOVA)).
