On the Food of the Antarctic Sea Anemone Urticinopsis Antarctica Carlgren, 1927 (Actiniidae, Actiniaria, Anthozoa) N
Journal of the Marine Biological Association of the United Kingdom, page 1 of 6. # Marine Biological Association of the United Kingdom, 2016 doi:10.1017/S0025315415002131 On the food of the Antarctic sea anemone Urticinopsis antarctica Carlgren, 1927 (Actiniidae, Actiniaria, Anthozoa) n. yu. ivanova1 and s.d. grebelnyi2 1Saint Petersburg State University, Saint Petersburg, Russia, 2Zoological Institute of Russian Academy of Sciences, Saint Petersburg, Russia The results of an investigation into coelenteron content of the Antarctic sea anemone Urticinopsis antarctica Carlgren, 1927 are presented. Remains of invertebrate animals and fishes were found in the gastrovascular cavity of anemones. Some of them were damaged by digestion and were considered as food items of U. antarctica. These items were molluscs Addamussium colbecki (Smith, 1902), Laevilacunaria pumilia Smith, 1879, Eatoniella caliginosa Smith, 1875 and one not strictly identified gastropod species from the family Rissoidae; a crinoid from the family Comatulida; sea-urchin Sterechinus neumayeri Meissner, 1900; ophiuroid Ophiurolepis brevirima Mortensen, 1936 and a fish Trematomus sp. In contrast to the prey men- tioned above, three specimens of amphipods Conicostoma sp. were not destroyed by digestion. They may represent commen- sals, which live in the gastrovascular cavity of the anemone.

CNIDARIA Corals, Medusae, Hydroids, Myxozoans
FOUR Phylum CNIDARIA corals, medusae, hydroids, myxozoans STEPHEN D. CAIRNS, LISA-ANN GERSHWIN, FRED J. BROOK, PHILIP PUGH, ELLIOT W.

SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell. -

In attacking the problem, the most expedient procedure is to study in detail the various components of the plankton, for it is well known that these components in varying degrees of importance provide directly the basic food for the Fig. -

We compared 16S rRNA sequences of bacterial strains isolated from stomachs of healthy krill Nyctiphanes simplex specimens with sequences of bacterial isolates and sequences of natural bacterial communities from the hemocoel of N. simplex specimens infected with P. brintoni to determine possible trans- mission pathways. All P. brintoni endoparasitic life stages and the transmission tomite stage (out- side the host) were associated with bacterial assemblages. -
Parasite Diversity of Nyctiphanes Simplex and Nematoscelis Difficilis (Crustacea: Euphausiacea) Along the Northwestern Coast of Mexico

C.P. 04510, México 3Australian Antarctic Division, Department of Environment, Water, Heritage and Arts, 203 Channel Highway, Kingston, Tasmania 7050, Australia ABSTRACT: The diversity of parasites found on Nyctiphanes simplex and Nematoscelis difficilis (Order Euphausiacea) was compared during 10 oceanographic cruises made off both coasts of the Baja California peninsula, Mexico. We tested the hypothesis that N. simplex has a more diverse para- sitic assemblage than N. difficilis because it is a neritic species, has larger population abundance, and tends to form denser and more compact swarms than N. difficilis. These biological and behavioral features may enhance parasite transmission within swarms. We detected 6 types of ectoparasites: (1) epibiotic diatoms Licmophora sp.; (2) Ephelotidae suctorian ciliates; (3) Foettingeriidae exu- viotrophic apostome ciliates; (4) an unidentified epicaridean cryptoniscus larvae (isopoda); and 2 cas- trators: (5) the ectoparasitic Dajidae isopod Notophryxus lateralis and (6) the ellobiopsid mesopara- site Thalassomyces fagei. We also detected 7 types of endoparasites: (1) an undescribed Collinia ciliate (Apostomatida); 3 types of Cestoda: (2) a Tetrarhynchobothruium sp. -
Kawamura, A. a Review of Food of Balaenopterid Whales. 155-197
A REVIEW OF FOOD OF BALAENOPTERID WHALES AKITO KAWAMURA Faculty of Fisheries, Hokkaido University, Hakodate, Hokkaido ABSTRACT In order to elucidate what species among so many kind of marine organ isms are likely to be consumed largely by the balaenopterid whales, the ex isting evidence on the food habits of baleen whales is reviewed. To meet with this primary purpose the report was mainly focussed on to describe qualitative aspects of food species having been known to date from the notable whaling grounds over the world rather than documenting quantitative subjects.' One of interesting facts noticed throughout the contribution was that there exists fairly intense diversity in the assembly of food species composition by regions such as; northern hemisphere vs. southern hemisphere, Pacific region vs. Atlantic region, inshore waters vs. offshore waters, embayed waters vs. open waters, where the former usually shows more div'ersed complexity than the latter. The fact however suggests that although the composition of food spe cies locally varies over the various whaling grounds, the food organisms as taxonomical groups are very similar one another even in locally isolated whal ing grounds when the food organisms and their assemblies are considered by the family or genus basis. In this connection many evidences given in the text may suggest that the balaenopterid whales as a whole may substantially live on quite simply compositioned forage assembly in comparison with tre mendous variety of organisms existing in the marine ecosystems. One of im portant aspects of the baleen whales food must be found in their characteris tics of forming dense swarms, schools, and/or aggregations in the shallower enough layers to be fed by the whales. -

The Development of Monitoring Options for UK MPAs: Fladen Grounds R&D Case Study Summary In July 2014, 30 Nature Conservation Marine Protected Areas (NCMPAs) were designated in the seas around Scotland, of which 13 are located beyond 12 nautical miles. Introduced under the Marine (Scotland) Act (2010) for inshore waters, and the Marine and Coastal Access Act (2009) for offshore waters, NCMPAs have been introduced to ensure the full range of nationally important features in Scotland’s waters are represented in the MPA network. The Central Fladen NCMPA in the Northern North Sea has been designated for the protection of the burrowed mud feature, including both the seapen and burrowing megafauna in circalittoral fine mud, and tall seapen components, and for the sub-glacial tunnel valley representative of the Fladen Deeps Key Geodiversity Area.
