Males release clouds of milt to fertilize the eggs as they are released into the water column.

Males trail the female and fertilize the eggs.

Intromittent organs are found most often in terrestrial species, as most aquatic species fertilize their eggs externally, although there are exceptions.

The females, which are mouth brooders, choose which male they want to fertilize their eggs.

Their sterility makes them unable to fertilize the eggs as the dragons express it.
