The creature can move before and after it makes an attack while swimming.
Prerequisite: Swim speed.
Benefit: When swimming, the creature can take a move action and another standard action at any point during the move. The creature cannot take a second move action during a round it makes a swim-by attack.
Normal: Without this feat, the creature takes a standard action either before or after its move.
