Changes in scleractinian coral Seriatopora hystrix morphology and its endocellular Symbiodinium characteristics along a bathymetric gradient from shallow to mesophotic reef
It is found that total chlorophyll concentration per zooxanthellae cell and the dark- and light-acclimated quantum yield of photosystem II did not vary significantly along the 60-m gradient, however, the chlorophyLL a/c ratio increased with depth, suggesting that the symbiotic algae in S. hystrix has two depth-dependent ecophenotypes.

In this study the bacteria were the primary shapers of the complex DOC continuum, suggesting higher trophic levels possibly have less of an impact on the qualitative composition of DOC than previously assumed.
Comparative genomics explains the evolutionary success of reef-forming corals
Transcriptome and genome data from twenty stony coral species and a selection of reference bilaterians were studied to elucidate coral evolutionary history. We identified genes that encode the…

A novel fluorescent protein isolated from warm water coral, which is named vivid Verde fluorescent protein (VFP), matures readily at 37 °C and emits bright green light and characterizations revealed that VFP has a tendency to form dimers.
The Covert World of Fish Biofluorescence: A Phylogenetically Widespread and Phenotypically Variable Phenomenon
It is shown that biofluorescence is not only phylogenetically widespread, but is also phenotypically variable across both cartilaginous and bony fishes, highlighting its evolutionary history and the possibility for discovery of numerous novel fluorescent proteins.

Analysis of the patterns of fluorescent protein distribution provides evidence that the scheme in which fluorescent proteins are distributed among the anatomical structures of corals is nonrandom and may function as a signaling mechanism to organisms with sensitivity to specific wavelengths of light.

The results demonstrate the feasibility of applying ML to sperm whale bioacoustics and establish the validity of constructing neural networks to learn meaningful representations of whale vocalizations.
A New Mesophotic Clingfish (Teleostei: Gobiesocidae) from the Bahamas
A new species of clingfish belonging to the genus Derilissus is described from a deep coral wall in the Exumas, Bahamas, characterized by bright orangish-red coloration on the flank, a yellow head, and a prominent black oval marking on the caudal peduncle.
