Short-finned pilot whale	0	2,741	n/a
1  Scalar ratios were not applied in this case due to brief survey duration.
2  Best abundance estimate. For most taxa, the best abundance estimate for purposes of comparison with take estimates is considered here to be the model-predicted abundance (Garrison et al., 2023). For Rice's whale, Atlantic spotted dolphin, and Risso's dolphin, the larger estimated SAR abundance estimate is used.
3  Modeled take of 3 increased to account for potential encounter with a group of average size (Maze-Foley and Mullin, 2006).
4  Modeled take of 13 increased to account for potential encounter with a group of average size (Maze-Foley and Mullin, 2006).
5  The “blackfish” guild includes melon-headed whales, false killer whales, pygmy killer whales, and killer whales.
