Although being more biohermal in form. the Pliocene reef system under Miami appeared to have distinct zonation, with evidence of four ecological zones being collected at the sampling sites. These zones included the high-energy. reefcrest Millepora­ Trochita Zone (Zone I), the reef platform lJip[oria-Gorgonian Zone (Zone 2), the back reef Porites-Septastrea Zone (Zone 3), and a lagoonal Thalaesio- Turritella Zone (Zone 4) to the west of the reef tract. Based upon both the extent of the Atlantic Coastal Ridge and the implied faunal zonation of the reefs, it is conjectured that the Pliocene reef tract produced the original topographic high along the southeasterncoast ofFlorida. This was latercovered by a crust of oolitic limestone and sand in the late Pleistocene to produce the Atlantic Coastal Ridge. Similar Pliocene reeftracts are known from southwestern and southern Florida. and these linked with the eastern reef tract to form an atoll-like structure around a central. lagoon-like basin. The southern part of this basin infilled with carbonate sediments. and during subaerial exposure in the early Pleistocene, produced the Tamiami Formation. Together, the atoll-like Pliocene reeftracts and the central lagoon-like basin laid down the geomorphological framework for the formation of the Everglades in the Holocene. The Everglades is now seen to be reef-controlled. Fourteen new gastropod species. all index fossils for the reeffacies ofthe Buckingham Formation, and a new genus ofhard substrate muricid gastropods, are proposed.

Since August, 1983, draglines used in construct­ ing artificial lakes have broughtup large amounts of highly fossiliferous sediments at several sites near SW 146 th Avenue and Bird Road in Greater Miami, all from depths of approximately 15-20 m. While visiting four of these sites, I found that the marly sediments contained a pure and species-rich as­ semblage of Buckingham-Duplin marine inverteb­ rates.

  • ABSTRACT Title of Dissertation: PATTERNS IN
    ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range.

  • CONE SHELLS - CONIDAE MNHN Koumac 2018
    Living Seashells of the Tropical Indo-Pacific Photographic guide with 1500+ species covered Andrey Ryanskiy INTRODUCTION, COPYRIGHT, ACKNOWLEDGMENTS INTRODUCTION Seashell or sea shells are the hard exoskeleton of mollusks such as snails, clams, chitons. For most people, acquaintance with mollusks began with empty shells. These shells often delight the eye with a variety of shapes and colors. Conchology studies the mollusk shells and this science dates back to the 17th century. However, modern science - malacology is the study of mollusks as whole organisms. Today more and more people are interacting with ocean - divers, snorkelers, beach goers - all of them often find in the seas not empty shells, but live mollusks - living shells, whose appearance is significantly different from museum specimens. This book serves as a tool for identifying such animals. The book covers the region from the Red Sea to Hawaii, Marshall Islands and Guam. Inside the book: • Photographs of 1500+ species, including one hundred cowries (Cypraeidae) and more than one hundred twenty allied cowries (Ovulidae) of the region; • Live photo of hundreds of species have never before appeared in field guides or popular books; • Convenient pictorial guide at the beginning and index at the end of the book ACKNOWLEDGMENTS The significant part of photographs in this book were made by Jeanette Johnson and Scott Johnson during the decades of diving and exploring the beautiful reefs of Indo-Pacific from Indonesia and Philippines to Hawaii and Solomons. They provided to readers not only the great photos but also in-depth knowledge of the fascinating world of living seashells. Sincere thanks to Philippe Bouchet, National Museum of Natural History (Paris), for inviting the author to participate in the La Planete Revisitee expedition program and permission to use some of the NMNH photos.

E-mail: [email protected] SUMMARY: Samples of a soft-bottom community from the continental slope of Campos Basin, off southeast Brazil, were obtained between 2001 and 2003 by the Research Vessel “Astro-Garoupa” with a 0.25 m2 box corer or by dredging with a Charcot dredge. A total of 177 samples were taken at depths ranging from 700 to 1950 m. Mollusks were present at all of the stations and among Gastropoda the Turridae showed the highest diversity. Within the family Cochlespirinae we found: Leucosyrinx tenoceras (Dall, 1889), L. verrillii (Dall, 1881), expanding the known distribution of the latter species farther south, and L.? subgrundifera (Dall, 1888), which is the first record of this species for the South Atlantic and the shallowest depth at which it has ever been found. Within the family Drilliinae we found Splendrillia centimata (Dall, 1889), also the first record of this species for the South Atlantic and its shallowest depth. Within the subfamily Oenopotinae we describe here three new species in the genus Oenopota Mörch, 1852: O. seraphina n. sp., O. diabula n. sp. and O. carioca n. sp. Keywords: deep-water, Turridae, Leucosyrinx, Splendrillia, Oenopota, Southwestern Atlantic, Brazil.
