Sex-specific bacterial microbiome variation in octopus vulgaris skin

Deiene Rodríguez-Barreto,
Juan Carlos Sanz-González,

et al.

Abstract: Growing knowledge of the host-microbiota of vertebrates has shown the prevalence of sex-specific differences in the microbiome. However, there are virtually no studies assessing sex-associated variation in the microbiome of cephalopods. Here we assess sex-specific variation in the common octopus (Octopus vulgaris) skin microbiome using amplicon sequencing targeting the V4 hypervariable region of prokaryote 16S rRNA genes. Skin and mantle-associated mucus was collected from wild adult individuals of common Octo… Show more

“…Females exhibited a two-fold higher relative abundance of unassigned sequences compared to males, suggesting that novel sequences may contribute to the observed sex differences (Wessels et al 2017). The mucous layer in the cephalopod Octopus vulgaris exhibits a sex-specific symbiosis in which microbes benefit from easy access to distinct substrates present in female and male skin, respectively (Rodríguez-Barreto et al 2024). Another example is the nematode Caenorhabditis elegans , where bacteria exhibit sex-specific effects, leading to differential developmental rates in males and females (Santos et al 2023).…”
