Some Opisthobranchs from West Africa
SOME OPISTHOBRANCHS FROM WEST AFRICA BY KATHLEEN M. WHITE, Ph. D., M. Se. (Reading) 12 SOME OPISTHOBRANCHS FR OM WEST AFRICA The following report is based upon material submitted to me by the Director oi' the Institut Royal des 'Sciences Naturelles of Belgium whom I wish to thank for the opportunity of examining it. It comprises material eollected by the training-ship « Mercator » on lier 9th voyage in 1935-6, her llth voyage in 1936-7 and her 14th voyage in 1937-8. Additional specimens were eollected by the Belgian expédition to the South Atlantic in 1948-49 and from West Afriea in 1953. The région covered is the west coast of Africa from Bio de Oro in the north to Angola on the south, and it lies roughly between longitudes 17° West to 13° East and latitudes 26° North and 15° South. The depths extend from shore down to 50 fathoms. The Opisthobranchs of tliis région have received no attention. Collections from Morocco in the north have been reported upon bv A. Pruvot-Fol in 1927 and 1953 and bv J. Risbec in 1931. Collections from S. Africa have been described bv R. Bergh in 1908, K. H. Barnard in 1927, C. H. O'Donoghue in 1928 and N. B. Eales and H. Engel in 1935. References to these reports have heen made and to A. Vayssiere's accounts of the Mediterranean fauna publislied between 1865 and 1919. In all twenty-six species of Opisthobranchs have been recognised of which eighteen are previously described species, two are new varieties of know species and four appear to be new species. -
Prey Preference Follows Phylogeny: Evolutionary Dietary Patterns Within the Marine Gastropod Group Cladobranchia (Gastropoda: Heterobranchia: Nudibranchia) Jessica A
Goodheart et al. BMC Evolutionary Biology (2017) 17:221 DOI 10.1186/s12862-017-1066-0 RESEARCHARTICLE Open Access Prey preference follows phylogeny: evolutionary dietary patterns within the marine gastropod group Cladobranchia (Gastropoda: Heterobranchia: Nudibranchia) Jessica A. Goodheart1,2* , Adam L. Bazinet1,3, Ángel Valdés4, Allen G. Collins2 and Michael P. Cummings1 Abstract Background: The impact of predator-prey interactions on the evolution of many marine invertebrates is poorly understood. Since barriers to genetic exchange are less obvious in the marine realm than in terrestrial or freshwater systems, non-allopatric divergence may play a fundamental role in the generation of biodiversity. In this context, shifts between major prey types could constitute important factors explaining the biodiversity of marine taxa, particularly in groups with highly specialized diets. However, the scarcity of marine specialized consumers for which reliable phylogenies exist hampers attempts to test the role of trophic specialization in evolution. In this study, RNA- Seq data is used to produce a phylogeny of Cladobranchia, a group of marine invertebrates that feed on a diverse array of prey taxa but mostly specialize on cnidarians. The broad range of prey type preferences allegedly present in two major groups within Cladobranchia suggest that prey type shifts are relatively common over evolutionary timescales. Results: In the present study, we generated a well-supported phylogeny of the major lineages within Cladobranchia using RNA-Seq data, and used ancestral state reconstruction analyses to better understand the evolution of prey preference. These analyses answered several fundamental questions regarding the evolutionary relationships within Cladobranchia, including support for a clade of species from Arminidae as sister to Tritoniidae (which both preferentially prey on Octocorallia). -

On Melanochlamys Cheeseman, 1881, a Genus of the Aglajidae (Opisthobranchia, Gastropoda) 1 W. B. RUDMAN2 ABSTRACT: Melanochlamys Cheeseman, 1881, long considered to be a synonym of Aglaja Renier, 1807, is shown to be a distinct genus of the Aglajidae differing from other genera in external body form, shape of shell, alimentary canal, and re productive system. Specimens of the type species, M. cylindrica Cheeseman, 1881, are compared with M. lorrainae (Rudman, 1968), M. queritor (Burn, 1958), and M. diomedea (Bergh, 1893). It is suggested that Aglaja dubia O'Donoghue, 1929, A. ezoensis Baba, 1957, A. henri Burn, 1969, A. nana Steinberg & Jones, 1960, and A. seurati Vayssiere, 1926, also belong to Melanochlamys. IN 1881, Cheeseman described a new species the anterior half of the dorsum and posteriorly of aglajid from New Zealand, and, because of the edge is rounded forming a small loose flap. differences in the external form of the body Sometimes there is a small central indentation and nature of the shell, he erected a new genus on the posterior edge of the headshield.

The 1907; O'Donoghue, 1929) have considered this posterior half of the dorsum forms a posterior name to be a junior synonym of Aglaja Renier, shield. The hind end of this shield overhangs 1807. However, after an extensive study of the the posterior end of the body and encloses the family, I have come to the conclusion that reduced shell. -

Terpenoids in Marine Heterobranch Molluscs
marine drugs Review Terpenoids in Marine Heterobranch Molluscs Conxita Avila Department of Evolutionary Biology, Ecology, and Environmental Sciences, and Biodiversity Research Institute (IrBIO), Faculty of Biology, University of Barcelona, Av. Diagonal 643, 08028 Barcelona, Spain; [email protected] Received: 21 February 2020; Accepted: 11 March 2020; Published: 14 March 2020 Abstract: Heterobranch molluscs are rich in natural products. As other marine organisms, these gastropods are still quite unexplored, but they provide a stunning arsenal of compounds with interesting activities. Among their natural products, terpenoids are particularly abundant and diverse, including monoterpenoids, sesquiterpenoids, diterpenoids, sesterterpenoids, triterpenoids, tetraterpenoids, and steroids. This review evaluates the different kinds of terpenoids found in heterobranchs and reports on their bioactivity. It includes more than 330 metabolites isolated from ca. 70 species of heterobranchs. The monoterpenoids reported may be linear or monocyclic, while sesquiterpenoids may include linear, monocyclic, bicyclic, or tricyclic molecules. Diterpenoids in heterobranchs may include linear, monocyclic, bicyclic, tricyclic, or tetracyclic compounds. Sesterterpenoids, instead, are linear, bicyclic, or tetracyclic. Triterpenoids, tetraterpenoids, and steroids are not as abundant as the previously mentioned types. Within heterobranch molluscs, no terpenoids have been described in this period in tylodinoideans, cephalaspideans, or pteropods, and most terpenoids have been found in nudibranchs, anaspideans, and sacoglossans, with very few compounds in pleurobranchoideans and pulmonates. Monoterpenoids are present mostly in anaspidea, and less abundant in sacoglossa. Nudibranchs are especially rich in sesquiterpenes, which are also present in anaspidea, and in less numbers in sacoglossa and pulmonata. Diterpenoids are also very abundant in nudibranchs, present also in anaspidea, and scarce in pleurobranchoidea, sacoglossa, and pulmonata. -
