Dear Josh:

The male and the female swim next to each other and then engage in
rolling, flippering, and tail fluking. Both dive and then surface
vertically with their ventral surface in contact with each other.  That
is when copulation takes place.  They usually breed in warmer waters.
Their gestation period is babout 11 months.

Best wishes,
