| CONCH-L LISTSERV |
A mailing list on a LISTSERV supported by the University of Georgia (UGA). Members subscribe to "the list" to facilitate an easy exchange of emails via "posting" one email to "the list" which is distributed by the Listserve to all subscribers of the list to which the initial email was sent. See also: GASTROPODNET; MOLLUSCAlist; STROMBUS-L; SHELLFISH. See the compilation of information about Molluscan Listserves. |
|
| CURVED | Arched or gently bent; = ARCUATE. | |
| GASTROPODNET LISTSERV |
A mailing list on a LISTSERV which is hosted by Georgia State University (GSU) for "researchers using molluscs as model systems". See also: CONCH-L; MOLLUSCAlist; STROMBUS-L; SHELLFISH. See the compilation of information about Molluscan Listserves. |
|
| INCURVED | Curved inwardly toward the shell or upward and inward toward the SPIRE; see: INFLECTED. | |
| INTERVAL | A space or gap, in many cases between sculptural or color elements; synonymous with INTERSPACE, when applied to ornament. | |
| INTERVARICAL | Lying between two VARICES. | |
| INTERVARICAL SPACE | The area between one VARIX and another; a shell area indicative of active growth. | |
| LARVA (pl. LARVAE) |
The juvenile stage, following the egg, of many forms of life; usually provides a mechanism for dispersal of the species; see also: DORATOPSIS; ECHINOSPIRA; GLOCHIDIUM; LECITHOTROPHIC; NEOTENY; PEDIVELIGER; PLANKTOTROPHIC; PROTOCONCH; RHYNCHOTEUTHIS; SPAT; TROCHOPHORE; VELIGER. | |

| LISTSERV also: LISTSERVE |
"LISTSERV"® is a licensed registered trademark for an "opt-in" mailing list system that permits people to send one email which gets distributed automatically to many other people with similar interests. This system was developed in 1986 and licensed/registered by L-Soft. The term has come to be used rather loosely to refer to any such system.

| NOMEN CONSERVANDUM | [need definition]. | |
| PARALARVA | In CEPHALOPODS, the first free-living form of the organism, typically found in surface PLANKTON. | |
| POSTLARVAL | After the LARVAL stage; after METAMORPHOSIS.. | |
| RECURVED | Curved or bent backward; when used in reference to symmetrical CONICAL univalves, signifies that the apex is turned towards the posterior margin (as in Emarginula spp.); see also: DEFLEXED; REFLECTED; REFLEXED. | |
| RIGHT VALVE (abbrev: RV) |
That valve of a bivalve lying on the observer's right-hand side when the shell is placed with anterior end pointing away from the observer, and with COMMISSURE vertical, the hinge being uppermost; see also: LEFT VALVE. Visit Let's Talk Seashells for how to distinguish between right and left valves. | |
| RV | Abbreviation for "RIGHT VALVE" of a bivalve shell. See also: LV. | |
| SHELLFISH LISTSERV |
A mailing list on a LISTSERV hosted by the National Shellfisheries Association (NSA). "The purpose of the Forum e-mail list is to promote open exchange of ideas among those working with or interested in any aspect of shellfisheries - research, management, regulation, commercial production, etc." Another "SHELLFISH" mailing list is provided by the Washington State Department of Health as a service to the shellfish industry and partner agencies and organizations who are involved in commercial shellfish harvest management. See also: CONCH-L; GASTROPODNET; MOLLUSCAlist; STROMBUS-L. See the compilation of information about Molluscan Listserves. |

| STROMBUS-L LISTSERV |
A mailing list on a LISTSERV which is hosted by the Gulf and Caribbean Fisheries Institute (GCFI) and is dedicated to "Queen conch fisheries, management, conservation, aquaculture, restoration".
