  abstract = {{T}he capacity of marine sponges to cope with environmental changes is often attributed to the specific composition of their bacterial communities. {I}n this study, we assessed the bacterial microbiome of two dominant sponges, {R}habdastrella globostellata ({R}g) and {H}yrtios erectus ({H}e), living in the {B}ourake lagoon ({N}ew {C}aledonia), where abiotic conditions daily fluctuate according to the tide. {S}ponge specimens, sediment and seawater samples were collected at 2-3 m depth. {T}he bacterial communities were assessed using 16{S} r{RNA} metabarcoding, and variations between the two sponges were compared using {PCA} biplots. {C}hloroflexi was the dominant phyla in both {H}e and {R}g with an average relative abundance of 41.2% and 53.2%, respectively, while it was absent in sediment and seawater. {A}mong the phylum {C}hloroflexi, {SAR}202 clade was dominant in both sponges, reaching an average relative abundance of 53.2% ({H}e) and 78.7% ({R}g). {P}rincipal component analysis ({PCA}) was used to identify the main variables driving the bacterial community structure in both sponges. {T}he results indicated that the bacterial community structure in both sponges was strongly associated with {C}hloroflexi (70.9% of the phyla variance) and {SAR}202 clade (86.6% of the clade variance). {T}he high relative abundance of the phylum {C}hloroflexi and the {SAR}202 clade observed in this study is the highest reported so far in the literature in marine sponges. {S}uch a high relative abundance of these bacteria could suggest their involvement in the well-being of sponges in the extreme environmental conditions of {B}ourake.},
