Abstract Marine sponges play a vital role in the reef's benthic community; however, understanding how their diversity and abundance vary with depth is major challenge, especially on marginal reefs areas deeper than 30 m. To help bridge this gap, we used underwater videos at 24 locations between 2‐ 62‐meter depths reef system Southwestern Atlantic to investigate effect of sponge metacommunity. Specifically, quantified abundance, density, taxonomic composition communities, decomposed gamma ( γ ) into alpha α beta β components. We also assessed whether was driven by species replacement (turnover) or nesting local communities (nestedness). identified 2020 marine individuals, which belong 36 genera. As expected, deep (i.e., those greater m) presented more eightfold number per square meter compared shallow areas. About 50% that occurred (<30 Contrarily expectations, rare 0 D ), typical 1 dominant 2 did not depth, but had ones, for species. Between 92.7% 95.7% given turnover both inside Our results support previous studies found density reveal sorting stronger smaller depths, generating across Because driver any entire gradient should be considered management conservation strategies.
