Figure 6: Global Distribution of Titanium Levels in Male Sperm Whales. This figure shows the global distribution of mean Ti levels in 105 male sperm whales grouped by sampling region. 1No male whales were found in the Cocos or Kiribati regions; 2Specific regions are named for the nearest body or ocean region; 3All data are presented in ug total Ti/g tissue wet weight +/- standard error. There were no statistical differences among regions at a significance level of p = 0.05.
