Deep-sea animals are not very abundant, yet they must encounter one
another for sexual reproduction to maintain the populations. Many species
have sexually dimorphic light organs and it is assumed that these
facilitate sexual encounters.
I give some examples of the known numbers of some fish and crustaceans
and discuss whether luminous signals can provide the primary sensory
channel for species recognition.
