“…Recently, Kotlyar () revised the taxonomy of the melamphaid genus Poromitra , describing seven of its 22 currently recognized species. With the exception of Poromitra jucunda Kotlyar 2010, whose description was based on the astonishing (for the group) number of 42 specimens, all other new species descriptions were based on one to seven specimens.…”

“…Adults usually occur below 100-200 m (some at depths greater than 3000 m), while juveniles occur in shallow oceanic waters.

The Stephanoberycoidei includes 23 genera and c. 94 species of deep-sea teleosts commonly known as bigscales, pricklefishes, gibberfishes and whalefishes. Stephanoberycoidei is one of the least known groups of deep-sea fishes, in spite of their apparent relative abundance in meso and bathypelagic depths. Nine species of the Stephanoberycoidei are reported here for the first time in Brazilian waters, and most of them represent new range extensions for the south-western Atlantic Ocean. Those species are Melamphaes polylepis, Melamphaes typhlops, Poromitra sp. and Scopeloberyx robustus (Melamphaidae), Acanthochaenus luetkenii and Stephanoberyx monae (Stephanoberycidae), Rondeletia bicolor and Rondeletia loricata (Rondeletiidae) and Gyrinomimus sp. (Cetomimidae). Occurrences of the pricklefish Scopelogadus mizolepis (Melamphaidae), the gibberfish Gibberichthys pumilus (Gibberichthyidae) and the velvet whalefish Barbourisia rufa (Barbourisiidae) are confirmed in the Brazilian exclusive economic zone, but previously published records of Poromitra capito and Melamphaes simus (Melamphaidae) in the region most likely represent misidentifications. Validities of the recently described Poromitra kukuevi and Poromitra indooceanica are discussed in light of new specimens of the genus collected in the south-western Atlantic Ocean. An identification key for the 13 species of Stephanoberycoidei reported off Brazil is also provided.

This paper is a checklist of the fishes that have been documented, through both published and unpublished sources, in marine and estuarine waters, and out 200 miles, from the United States-Canadian border on the Beaufort Sea to Cabo San Lucas, Mexico. A minimum of 241 families and 1,644 species are known within this range, including both native and nonnative species. For each of these species, we include maximum size, geographic and depth ranges, whether it is native or nonnative, as well as a brief mention of any taxonomic issues.

Trimethylamine oxide accumulation as a function of depth in Hawaiian mid-water fishes

6Trimethylamine oxide (TMAO) is a common osmolyte and counteracting solute. It is believed to 7 combat the denaturation induced by hydrostatic pressure as some deep-sea animals contain 8 higher TMAO levels than their shallow water counterparts. It has also been proposed that TMAO 9 may accumulate passively during lipid storage resulting in a correlation between lipid content 10 and TMAO levels in some groups. Previous research showed that lipid content decreased with 11 depth in species of Hawaiian fishes presenting a novel test of these competing hypotheses. 12 TMAO ranged from 20.4 to 92.8 mmol/kg. Lipid content ranged from 0.50 to 4.7 % WW. After 13 completing a comprehensive search for depths available in the literature, provided here, we 14 analyzed TMAO and lipid as a function of average, minimum and maximum depth of occurrence 15 for 27 species of fishes from nine orders. We found that TMAO is positively correlated with all 16 measures of habitat depth (hydrostatic pressure) but the relationship is strongest with average 17 depth. We further showed using phylogenetic independent contrasts that this relationship was not 18 influenced by the evolutionary relatedness of these species. Interestingly, we found that lipid 19 content increased with depth, in direct contrast to previous studies. TMAO is thus also 20 positively correlated with lipid content. While we are unable to distinguish between these 21 hypotheses, we show that TMAO is strongly correlated with depth in mid-water fishes. 22Key Words: trimethylamine oxide (TMAO); lipid; chemical composition; hydrostatic 23 pressure; depth; Hawaiian fish 24 335 20 We thank Jeff Drazen for his assistance identifying fishes.
