Since males migrate southwards to breed with females in warmer waters, the degree of reproductive isolation in the North Atlantic is uncertain. Unlike the case of the double penis of the snakes and lizards, where each of the penises functions alone like a sole penis by itself, in this case, they approach each other and unite during the copulation, forming a channel through which the sperm liquid is eliminated. Certain oceanographic features attract higher concentrations of individuals, with population density generally increasing near to the continental shelf and around seamounts. Each of the two penises has a cartilaginous support inside and a groove on their inner edge.
