Abstract
Knowledge of living crinoids from Brazil is chiefly restricted to the contributions of Dr Luis Roberto Tommasi between the decades of 1950 and 1970. Herein we present an updated catalogue of the crinoids occurring along the Brazilian coast, including data on synonyms, type localities, type material, geographical distribution, bathymetric ranges, and occurrences of species along the coast. The data is based on an extensive revision of the literature and on a survey of several databases. A total of 20 species were catalogued, of which two are endemic (Phrixometra longipinna var. brasiliensis and Thaumatometra minutissima). According to information from the literature, P. longipinna var. brasiliensis represents an undescribed taxon. Although Brazil supports the greatest number of crinoid species in the Southwestern Atlantic, its crinoid fauna remains understudied and likely underestimated. Research on crinoids remains a subject of great potential, not only for taxonomy but also for other areas of knowledge.

Abstract
Sandstone reefs may be considered a unique geomorphologic feature within the subtropical Southwestern Atlantic Ocean region; however, biodiversity on these reefs has received little to no attention. Herein, we recorded the fish assemblage and benthic cover of sandstone reefs between 23 and 29 m depth in Southern Brazil and evidenced potential threats to habitat health. Video analysis and underwater censuses recorded 30 fish species. The unexpected high biomass of Epinephelus marginatus indicated that sandstone reefs may contain suitable habitats for the recovery of this endangered species. A rich benthic coverage including bryozoans, algae, hydrozoans, sponges, and octocorals increased local habitat structural complexity. However, a wide diversity of tangled fishing gear and broken sandstone slabs suggested that a valuable feature from Southern Brazil seascape is being lost by cumulative fishing impacts. An extensive mapping of sandstone reefs is urgently needed for better delineation of marine protected areas network in Southeast and Southern Brazil.
