Biology And Distribution Of Species Of Polyacanthonotus (Pisces, Notacanthiformes) In The Western North-Atlantic, Re Crabtree, Kj Sulak, Ja Musick

The notacanthid genus Poiyacanthonotus is represented in the Atlantic by three species of demersal deep-sea fishes at depths from about 500-3,800 m. Recent collections have made available new material from the temperate and tropical western North Atlantic for life history study of P. merretti and P. rissoanus. Species of the genus are browsers on small benthic macrofauna including polychaetes, gammaridean amphipods, and mysids. Reproduction does not appear to be seasonal. Fecundity is positively correlated with size in P. merretti, and ranges between 1,900-5,700 ova. Fecundities are much higher (ca. 20,000-30,000 ova) in P. rissoanus and P. cha/lengeri, which attain a …

Monomitopus magnus new species is described from slope waters off the southeastern coast of North America. M. magnus is most closely related to M. american urn from the continental slope of Uruguay and southern Brazil and is more distantly related to the western Pacific M. pallidus. M. magnus differs from M. americanum in having fewer developed gill rakers on the anterior arch (10-11 compared to 14-22) and more precaudal vertebrae (15 compared to 13-14). The 13 nominal species of Monomitopus are divided into three groups based on head shape and degree of ossification.

Abyssal fishes of the Caribbean Sea are known from the work of six research vessels, yet only one ofthese collections has been reported. The most recent collection, that of the USNS BARTLETTin 1981, contains 13 new records of rare fish to the Caribbean, including two undescribed species. Twelve species accounts are given, documenting the new finds, along with some taxonomic changes from previous reports. Zoogeographical analysis revealed that the abyssal fish fauna of the Caribbean basins reflects a depauperate, tropical, western Atlantic subunit of a broader, circumglobal pattern of the world's abyssal fish fauna.
