Standard 4 Process Skills: 6 Abstract: In this lab, students will be introduced to the concept of a dichotomous key through the use of preliminary activities modeled by the teacher. They will then learn about the ecology and biology of selected marine mollusks, before putting their dichotomous key-reading skills to the test on 8 or 12 corresponding seashells. Finally, students demonstrate their new knowledge by creating their own dichotomous key to classify even more shells.

Marine Gastropods of American Samoa Introduction
Micronesica 41(2):237–252, 2011 Marine gastropods of American Samoa D.P. Brown Isle Royale National Park, Houghton, MI 49931 Abstract—Collected for food for over 3,000 years by the indigenous Samoan people, marine gastropods in American Samoa have never been collected and cataloged for science. This study documents 385 marine gastropods from 50 families occurring in the U.S. territory of American Samoa. Ten of these are listed by genus only and one by family. The num- ber of gastropods currently reported is likely significantly underestimated and a conservative estimate of the richness yet to be discovered. Introduction Molluscs have been collected in Samoa since the earliest inhabitants arrived some 3,000 years ago (Craig et al 2008, Kramer 1994, Kirch and Hunt, 1993, Nagaoka 1993). Much of this reef gleaning was directed at the cephalopods, the large and colorful giant clams (Tridacna spp.) and the larger marine snails such as Trochus spp, Lambis spp., Cassis spp., Turbo spp., and Tutufa spp., although any marine mollusc was likely taken if found (Munro 1999). While the limited archeological evidence provides an initial species list, this long history of the use of marine molluscs provided a very limited understanding of the marine gastro- SRGVRIWKHDUFKLSHODJR(YHQDIWHU(XURSHDQFRQWDFWIHZVHULRXVRUDPDWHXUVKHOO collectors made the long voyage to the S. Pacific to catalog the gastropoda. Until very recently, and before the advent of SCUBA, much of the gastropod knowledge in the area came from the shallow depths available to free-divers, what could be dredged off the bottom, and what washed onto the shore. The first organized sci- entific investigations into the Samoan gastropods weren’t carried out until the 18th century by the La Perouse expedition. -

They include the two families Mitridae and Costellariidae, similar in shell morphology and traditionally treated as close relatives. Some genera of deep-water Ptychatractidae and Volutomitridae are close to miters in shell morphology, and the term ‘mitriform gastropods’ has been introduced to refer to Mitridae, Costellariidae, and this assortment of convergent forms. The present study aimed at the re- construction of phylogenetic relationships of mitriform gastropods based on representative taxon sampling. Four genetic markers [cytochrome c oxidase subunit I (COI), 16S and 12S rRNA mitochondrial genes, and H3 (Histone 3) nuclear gene] were sequenced for over 90 species in 20 genera, and the molecular data set was supplemented by studies of radula morphology. -

Oliva Shells the Genus Oliva and the Species Problem

Costa Rica e@ernaL anatomy the Oliva animal Yuri KANTOR (") and Bernard TURSCH are the authors of this Chapter. FOR A FIRST GENERAL VIEW of molluscan anatomy see BRUSCA& BRUSCA(1990). For more detail, see FR~R& GRAHAM (1962). Drawings of live Oliua specimens are already present in the old literature. For instance, in Duc~os(1835-40) one finds good representations of Oliua elegans (PI. 32, figs. 1, 2), 0.flammulata (Pl. 30, figs. 3, 4), 0. miniacea (Pl. 31, fig. 7), 0. oliua (Pl. 7, figs. 2, 141, ?O.ponderosa (Pl. 31, fig. 8), 0. reticulata (Pl. 33, figs. 3,4 ), 0.scripta (Pl. 30, figs. 5, 6), 0.sericea (Pl. 32, figs. 5, 6) and 0. uidua (PI. 32, figs. 3, 4). The anatomy of only a few species of Oliua have been studied in detail. These are 0.peruuiana by KUT~LER(1913), 0.fulgurator f. circinata by MARCUS& MARCUS(1959a), 0,bulbosa and 0.sayana by KANTOR(1991), 0. oliua and 0. ouini by KANTOR& TURSCH (1998). Although the organs of all these species differ only in detail, some anatomical criteria effective at the specific level have been found. Future work will most probably reveal more. 6.1. external anatomy THE GENERAL ASPECT of the Oliua animal, removed from its shell, is shown in Figure 6.01. This drawing is purposely very incomplete and shows only a few of the organs. The proboscis (the entry point of the digestive system) is a retractable organ, and is mostly everted only for feeding activities. -

Phylum Mollusca
CHAPTER 13 Phylum Mollusca olluscs include some of the best-known invertebrates; almost everyone is familiar with snails, clams, slugs, squids, and octopuses. Molluscan shells have been popular since ancient times, and some cultures still M use them as tools, containers, musical devices, money, fetishes, reli- gious symbols, ornaments, and decorations and art objects. Evidence of histori- cal use and knowledge of molluscs is seen in ancient texts and hieroglyphics, on coins, in tribal customs, and in archaeological sites and aboriginal kitchen middens or shell mounds. Royal or Tyrian purple of ancient Greece and Rome, and even Biblical blue (Num. 15:38), were molluscan pigments extracted from certain marine snails.1 Many aboriginal groups have for millenia relied on mol- luscs for a substantial portion of their diet and for use as tools. Today, coastal nations annually har- vest millions of tons of molluscs commercially for Classification of The Animal food.
