However, dimensionality of imaging data, together with a great variability of nuclear shapes, presents challenges for 3D morphological analysis. Thus, there is a compelling need for robust 3D nuclear morphometric techniques to carry out population-wide analysis.

However, in contrast to most obligate bacteria, anomalopid symbionts have an active environmental phase that may be important for symbiont transmission. Here we investigated patterns of evolution between anomalopid symbionts compared with patterns in free-living relatives and unrelated obligate symbionts to determine if trends common to obligate symbionts are also found in anomalopid symbionts.

A few enigmatic bioluminescent symbionts have not been successfully cultured, which has led to speculation that they may be obligately dependent on their hosts. Here, we report the draft genome of the uncultured luminous symbiont of an anomalopid flashlight fish, 'Candidatus Photodesmus katoptron'.
