This study used 3D imaging techniques to analyze the crawling behavior of deep-sea octopuses (Muusoctopus robustus) observed during a single ROV dive at Davidson Seamount. The researchers quantified kinematic and locomotion characteristics, providing detailed insights into how these animals move in their natural habitat. However, the observations were limited to a single dive, which may not fully capture the variability in their behavior.

Seadragon genome analysis provides insights into its phenotype and sex determination locus

The study generated high-quality genome assemblies for the common seadragon and alligator pipefish, providing insights into the genetic basis of their unique traits. They found that genes involved in fin development were co-opted for the leaf-like appendages, and identified amhr2y as a putative male-specific sex determination gene.

The contribution of fisheries and aquaculture to the global protein supply

Fish and aquaculture contributed about 15.3% of the global animal-source protein for human consumption in 2018, with finfish being the primary source. Although aquaculture now produces a greater weight of aquatic animals, the protein contribution from capture fisheries was slightly higher due to differences in meat yields and protein concentrations. The study emphasizes the need for increased aquaculture production to meet growing protein demands but also highlights the environmental and food security challenges associated with using wild fish for feed.

Global determinants of freshwater and marine fish genetic diversity

Fish genetic diversity is not uniform across the globe, showing clear biogeographic patterns. Marine fish genetic diversity is positively correlated with sea surface temperature, while freshwater fish genetic diversity is strongly influenced by regional factors and average river slope, with South America as a hotspot.
