Abstract: ABSTRACT. A new species of the erect cheilostome bryozoan Cellaria Ellis & Solander, 1786 is described from Bahia, NE Brazil. Cellaria oraneae sp. nov. is the first formally characterized species of the genus reported from Northeastern coast of Brazil, distinguished from all congeners by the combination of hexagonal autozooids and rhomboid fertile zooids, hexagonal interzooidal avicularium with sagittate foramen, completely immersed ovicell with oval aperture and proximal rectangular lip. A brief discussion of… Show more

The cheilostome Bryozoa encrusting settlement panels deployed in the Azores between 0 and 500 m, which were retrieved after a time span of 1 and 2 years, are here described and figured. Of the 49 cheilostome species reported, 15 are new to science: Beania pauciserialis sp. nov., Caberea rylandi sp. nov., Micropora acorecia sp. nov., Cellaria acorensidolisi sp. nov., Hippothoa jakobseni sp. nov., Chorizopora lula sp. nov., Haplopoma freiwaldi sp. nov., Schizomavella (Schizomavella) reverteri sp. nov., Schizomavella (Schizomavella) kekrymmena sp. nov., Microporella avilai sp. nov., Microporella quadrispinosa sp. nov., Microporella lobopodia sp. nov., Microporella nodulifera sp. nov., Buffonellaria faialensis sp. nov., and Omalosecosa secunda sp. nov. The subspecies Glabrilaria orientalis azorensis (Harmelin, 1988) is here raised to species rank, resulting in Glabrilaria azorensis (Harmelin, 1988) comb. nov. Moreover, we designate a lectotype for Nimba praetexta Jullien in by Jullien & Calvet, 1903, type species of the genus Nimba Jullien in by Jullien & Calvet, 1903, redescribe the species based on scanning electron microscope inspection, and transfer the genus from the Lacernidae Jullien, 1888 to the Escharinidae Tilbrook, 2006. A lectotype is also designated for Schizobrachiella sanguinea (Norman, 1868). Based on the taxonomic account, we discuss changes concerning the recorded diversity of bryozoans in the Azores and their taxonomic assignment, now including 91 endemic species that account for 41% of a total of 221 bryozoan species reported from the archipelago. Finally, we discuss biogeographic relationships and the status of origin, including potential non-indigenous species, and demonstrate a strong relatedness with eastern Atlantic/Mediterranean faunas.

The common snook (Centropomus undecimalis) is a euryhaline fish with high commercial demand in the Mexican southeast, Caribbean, and South America. However, some aspects of its digestive physiology are still unknown, particularly in relation to lipid hydrolysis. Therefore, the characterization of the digestive lipase of this species was carried out. Our results show that the digestive lipase’s optimal temperature is 35 °C, being stable between 25 and 35 °C, and shows maximum activity at pH 9, with stability between pH 5 and 8. Different degrees of inhibition were presented by Orlistat (61.4%), Ebelactone A (90.36%), Ebelactone B (75.9%), SDS 1% (80.7%), SDS 0.1% (73.5%), and SDS at 0.01% (34.9%). Orlistat and Ebelactone A and B completely inhibited the lipase band in the zymogram, but not SDS addition. Lipase showed a molecular weight of 43.8 kDa. The high lipase activities in the digestive tract indicate the importance of lipids in the diet of C. undecimalis.
