The epidermis of Chondrichthyan fishes consists dermal denticles with production minimal but protein-rich mucus that collectively, influence the attachment and biofilm development microbes, facilitating a unique epidermal microbiome. Here, we use metagenomics to provide taxonomic functional characterization microbiome Triakis semifasciata (leopard shark) at three time-points collected across 4 years identify links between microbial groups host metabolism. Our aims include (1) describing...
Abstract Elasmobranch epidermal microbiomes are species-specific, yet microbial assembly and retainment drivers mainly unknown. The contribution of host-derived factors in recruiting an associated microbiome is essential for understanding host-microbe interactions. Here, we focus on the physical aspect host skin structuring communities. Each species elasmobranch exhibits unique denticle morphology, investigate whether communities functional pathways correlated with morphological features or...
The epidermal microbiome is a critical element of marine organismal immunity, but the virome organisms remains largely unexplored. epidermis sharks represents unique viromic ecosystem. Sharks secrete thin layer mucus which harbors diverse microbiome, while their hydrodynamic dermal denticles simultaneously repel environmental microbes. Here, we sampled from three shark species in family Carcharhinidae: genetically and morphologically similar Carcharhinus obscurus (n = 6) galapagensis 10)...
Characterizations of shark-microbe systems in wild environments have outlined patterns species-specific microbiomes; however, whether captivity affects these trends has yet to be determined. We used high-throughput shotgun sequencing assess the epidermal microbiome belonging leopard sharks (Triakis semifasciata) captive (Birch Aquarium, La Jolla California born and held permanently captivity), semi-captive (held for <1 year duration scheduled release; Scripps Institute Oceanography, San...
Marine host-associated microbiomes are affected by a combination of species-specific (e.g., host ancestry, genotype) and habitat-specific features environmental physiochemistry microbial biogeography). The stingray epidermis provides gradient characteristics from high dermal denticles coverage with low mucus to reduce levels mucus. Here we investigate the effects phylogeny habitat comparing epidermal Myliobatis californica (bat rays) rich epidermis, Urobatis halleri (round reduced two...
We present the first mitogenome sequence of Smoothnose Wedgefish, Rhynchobatus laevis obtained through field sequencing on MinION handheld sequencer. The mitochondrial genome R. is 16,560 bp in length and consisted 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA a non-coding control region (D-loop). GC content was at 40.1%. 867 length. Whole will enable improved understanding distribution, abundance, catch trade rates Critically Endangered species.
