Regarding "dolphin" murder. Apparently you don't understand that "murder" is a legal term used to identify the act of a human who has been convicted of murder.
As far as "dolphin" rape is concerned:
As far as "forced copulation", "infanticide" and other human developed concepts that some ignoramuses need to apply to animals because of their twisted ideology and politics...these are aspects of natural selection that have no moral implications.
Thus endeth the lesson.
Dolphins commit redrum and epar.
Better?
