How do obscure/rare sea creatures locate each other to breed?

This is a related fact about creatures that run into each other super rarely. Desert tortoises are a similarly very low density population. Females can store sperm from a mating event for several years before choosing to fertilize their eggs and produce offspring. This means that they can meet a mate when conditions aren't good for having babies, then have babies at a much later date when environmental factors are better (e.g. it actually rains).
