William Tab has shot this amazing and beautiful super macro image of, well, nudibranch sex! It shows the mating genitalia of two Nembrotha rutilans nudibranchs and was taken recently at Angel’s Window, Lembeh Strait, Indonesia. It was shot with a Canon 1DX SLR in a Nauticam housing, with a Canon EF 100mm f/2.8 Macro USM and a Nauticam SMC macro converter.

1/250 at f32 with light from 2 x Inon Z240 strobes.
