[84] Pods of female sperm whales sometimes protect themselves by forming a protective circle around their calves with their flukes facing outwards, using them to repel the attackers. [90]

As such, many sex-specific morphological adaptations (for example, in Dytiscidae diving beetles, females have setose dorsal furrows that males do not and males have suction cups on their forelegs that females do not [18]) are sexual dimorphisms caused by sexual coercion.
