Table 5

Mean and standard deviation hematology values for Antillean manatees from Puerto Rico for all sex classes (males and females, n = 70): males only, n = 33, and females only, n = 37, with ±1 standard deviation ranges in parentheses. Significant differences using values are indicated with an asterisk ().
