A study of stomach contents of Cory's shearwater, Calonectris diomedea borealis (Cory, 1881) (Aves: Procellariidae), from the Macaronesian Islands Naturalis
Hartog, J.C. den; Clarke, M.R..
Data are presented on the diet of Cory's Shearwater Calonectris diomedea borealis (Cory, 1881) resulting from stomach investigations based on 18 birds from Hierro (Canary Islands), 5 from Selvagem Grande (Selvagens or Salvage Islands), 2 from São Miguel and 1 from São Jorge (Azores), collected between 1977 and 1981. These data confirm the general idea that this shearwater feeds principally on fish and squid. The glandular stomachs of 9 birds from Hierro contained significant quantities of food, varying in wet weight from ca. 4-40 gm; in four cases more or less complete squids were present, all Ommastrephes bartrami (Le Sueur, 1821). In addition, the gizzards of all 26 birds, except one, contained fragments of squid beaks belonging to 12 species. Several of...

Cephalopods from the Netherlands Indian Ocean Programme (NIOP) (Expeditions 1992-1993) Naturalis
Salcedo-Vargas, Mario Alejandro.
Cephalopods of the Red Sea, Gulf of Aden and the Western Indian ocean off Somalia are studied. A preliminary annotated list is presented. This study was based on the examination of 381 specimens captured with a Rectangular Midwater Trawl (RMT8) during three cruises of the Netherlands Indian Ocean Programme. The taxa identified represent: 22 families, 35 genera and 56 species. Two species new to science are found. Systematic position and taxonomic re-evaluation in the Chiroteuthidae, Mastigoteuthidae and Octopodidae is briefly discussed. The present collections represent a valuable contribution to the species composition from the Western Indian Ocean and to cephalopod juvenile morphology.

Cephalopods from the Netherlands Indian Ocean Programme (NIOP)- I. Chiroteuthis spoeli n. spec. and Chiroteuthis picteti somaliensis n. subspec Naturalis
Salcedo-Vargas, Mario Alejandro.
Two new squids from the western Indian Ocean acquired during the Netherlands Indian Ocean Programme (NIOP) expeditions in 1992-1993 are described. The species new to science is Chiroteuthis (C.) spoeli, member of the subgenus Chiroteuthis s.str., which differs from the type species Chiroteuthis (C.) joubini chiefly in the enlarged suckers on arm II and III and the tentacular sucker morphology. The new subspecies is assigned to the subgenus Chirothauma in the species Chiroteuthis (C.) picteti and defined as Chiroteuthis (C.) picteti somaliensis, and is characterized by the sharp teeth in the arms. The genus Chiroteuthis, as now defined, consists of 2 subgenera, 7 species and 4 subspecies.

Cephalopods from the Netherlands Indian Ocean Programme (NIOP)- II. Mastigoteuthid lineage and related forms Naturalis
Salcedo-Vargas, Mario Alejandro.
Seven species of bathypelagic squids from the West Indian Ocean are described. Two species from the chiroteuthid lineage are recorded: Pianktoteuthis sp. and Chiroteuthis mega. The family Mastigoteuthidae is divided in two genera: Idioteuthis and Mastigoteuthis. As members of the former are Idioteuthis danae (=Echinoteuthis danae) and two species new to science, and for the latter Mastigoteuthis glaukopis and Mastigoteuthis grimaldii. The mastigoteuthid lineage is defined by: 1) short neck and brachial pillar; 2) whip-like tentacle; 3) ovate pseudoconus in cross section view, and 4) arm formula: IV>II>III≥I. The family Mastigoteuthidae as now defined consist of seventeen species.

Lima,Silvio Felipe Barbosa; Lucena,Rudá Amorim; Santos,Galdênia Menezes; Souza,José Weverton; Christoffersen,Martin Lindsey; Guimarães,Carmen Regina; Oliveira,Geraldo Semer.
Abstract: Coastal ecosystems of northeastern Brazil have important biodiversity with regard to marine mollusks, which are insufficiently studied. Here we provide an inventory of mollusks from two sites in the estuary of the Paraíba River. Mollusks were collected in 2014 and 2016 on the coast and sandbanks located on the properties of Treze de Maio and Costinha de Santo Antônio. The malacofaunal survey identified 12 families, 20 genera and 21 species of bivalves, 17 families, 19 genera and 20 species of gastropods and one species of cephalopod. Bivalves of the family Veneridae Rafinesque, 1815 were the most representative, with a total of five species. Gastropods of the family Littorinidae Children, 1834 had the greatest species richness. The most abundant...

Le régime alimentaire du poulpe commun, <Octopus vulgaris> Cuvier, 1797 (Cephalopoda, Octopodidae) de la côte du Sénégal (Atlantique Oriental Tropical) OceanDocs
Diatta, Y.; Clotilde-Ba, F. L.; Capape, C..
Le poulpe commun, Octopus vulgaris Cuvier, 1797 est une espèce clé dans l'économie des productions halieutiques au Sénégal, suite à une intrusion massive et une explosion démographique dans les eaux marines de ce pays, depuis les années 80. Pour expliquer le phénomène, on a estimé intéressant de connaître la place de l'espèce dans l'écosystème local par le biais de ses relations trophiques avec le milieu naturel. Au cours de prospections effectuées, de 1996 à 1998 inclus, sur le terrain et grâce à des séjours en mer, lors de campagnes chalutières, 459 O. vulgaris ont été récoltés. Leurs contenus stomacaux ont été analysés selon des méthodes classiques, qualitatives et quantitatives. O. vulgaris se nourrit régulièrement, toute l'année, d'organismes...

Mollusk bycatch in trawl fisheries targeting the Atlantic seabob shrimp Xiphopenaeus kroyeri on the coast of Sergipe, northeastern Brazil Pap. Avulsos de Zool. (São Paulo)
Mendonça,Luana Marina de Castro; Guimarães,Carmen Regina Parisotto; Lima,Silvio Felipe Barbosa.
Abstract The malacofauna bycatch of sea-bob shrimp Xiphopenaeus kroyeri (Heller, 1862) trawl fisheries on the coast of Sergipe was studied for 5 years. The malacofauna bycatch considered was obtained in nine oceanographic sampling campaigns carried out between May 1999 and June 2003 in 18 stations distributed in six transects along depths of 10, 20 and 30 m. A total of 2,669 individuals of mollusk belonging to 54 species were captured on the 18 sea-bob shrimp trawl stations carried out along the coast of Sergipe. The considerable richness of mollusks was composed by 19 families and 31 species of gastropods, 12 families and 19 species of bivalves and 2 families and 4 species of cephalopods. The highest abundance were observed at stations 13 (373...

O enigma da "reação espermatofórica": breve síntese do conhecimento sobre a estrutura e o funcionamento dos espermatóforos dos cefalópodes (Mollusca: Cephalopoda) Pap. Avulsos de Zool. (São Paulo)
Marian,José Eduardo Amoroso Rodriguez.
Cefalópodes coleóides (lulas, sépias e polvos) produzem espermatóforos muito complexos que são transferidos à fêmea durante a cópula por meio do hectocótilo, um apêndice modificado nos machos. Durante a transferência à fêmea, ocorre a chamada "reação espermatofórica", complexo processo de evaginação do aparato ejaculatório do espermatóforo, que conduz à exteriorização da massa espermática e corpo cimentante. A presente revisão sintetiza o conhecimento acerca da morfologia e funcionamento desta estrutura exclusiva dos coleóides, identificando lacunas e definindo estratégias que possibilitem avanços na área. Poucos trabalhos abordam com detalhes a morfologia e anatomia funcional dos espermatóforos dos cefalópodes, grande parte do conhecimento acerca da...

On organic remains in shells of Paleozoic and Mesozoic cephalopods (nautiloids and ammonoids) OMA
Grégoire, Ch..
Remnants of decalcified nacreous layers from Ordovician, Devonian, Carboneferous (including Pennsylvanian), Permian, Jurassic and Cretaceous, nautiloid and ammonoid shells, examined in the electron microscope, consists of various, biuret-positive structures, which reflect degrees in degradation of the original conchiolon sheets. Identification of these structures as altered nacreous concholin and discrimination from contaminating structures of foreign organisms, a frequent finding in fossil shells, were based on detection of similar structural modifications in the Recent <i>Nautilus</i> shell, in well preserved shells of Pennsylvanian and Mesozoic cephalopods and in alterations produced artificially in experimental diagenesis of the Recent...

Systematic value of the ultrastructure of the sucker surface in the squid family Mastigoteuthidae (Mollusca: Cephalopoda) Naturalis
Salcedo-Vargas, Mario Alejandro.
The ultrastructure of the sucker surface is described and its systematic value for mastigoteuthid squids, which bear minute suckers, is considered. An introduction to sucker terms is given and a redefinition of these terms is attempted. Using scanning electron microscopic data, two genera and four subgenera of Mastigoteuthidae from the Northwest Pacific are distinguished. The presence of “cushions” in the sucker is discussed and considered as a character important for understanding adaptations of cephalopods to the deep-sea.

The cycle of activity in the accessory nidamental glands from cephalopods OMA
Richard, A.; Van den Branden, C.; Decleir, W..
The reproductive system of female cephalopods includes a glandular system (oviduct glands and nidamental glands), which develops considerably during sexual maturation and which plays an important part in the formation of the different egg membranes. It is generally uncoloured. An exception are the nidamental glands in <i>Nautilus pompilius</i> which are composed of opaque yellowish or yellowish-green tissue (Ref. 1). Moreover all Sepioidea and Myopsida and <i>Ctenopteryx</i>, a species belonging to the Oegopsida (Ref.2) possess accessory nidamental glands. The most striking property of these glands is their intense coloration varying from yellow to orange and red. This paper is a comparative study of the accessory nidamental glands...
