Received: 16 January 2014; in revised form: 19 February 2014 / Accepted: 3 March 2014 / Published: 13 March 2014 Abstract: Sea angels, Clione limacina and Paedoclione doliiformis, are small, floating sea slugs belonging to Gastropoda, and their gonads are a bright orange-red color. Sea angels feed exclusively on a small herbivorous sea snail, Limacina helicina. Carotenoids in C. limacina, P. doliiformis, and L. helicina were investigated for comparative biochemical points of view. β-Carotene, zeaxanthin, and diatoxanthin were found to be major carotenoids in L. helicina. L. helicina accumulated dietary algal carotenoids without modification. On the other hand, keto-carotenoids, such as pectenolone, 7,8-didehydroastaxanthin, and adonixanthin were identified as major carotenoids in the sea angels C. limacina and P. doliiformis. Sea angels oxidatively metabolize dietary carotenoids and accumulate them in their gonads.

  • EN615 Cruise Report
    ADEON Recovery/Deployment Cruise Report #EN615 - RV Endeavor 06 – 25 June 2018 San Juan, Puerto Rico to Narragansett, RI Chief Scientist Joseph Warren, Jennifer Miksis-Olds, Carmen Lawrence, Brandyn Lucca, Hannah Blair, Sebastian Velez, Cassandra Fries, Peter Larios, Madison Alstede, Stephen Ell, 1 Jennifer Conyers, Andrew Heaney, Lindsay Olson, and Katharine Coykendall Cruise Summary The objectives for this cruise were to recover bottom landers at seven sites (Figure 1) along the shelfbreak (depths ranging from 200 – 900 m roughly), redeploy a bottom lander at each site after downloading its data, collect CTD profiles to characterize hydrographic conditions at the sites, conduct net sampling to collect biological specimens at each site, and conduct fine-scale (roughly 8 km by 8 km) multi-frequency acoustic surveys at each site (Figure 2). All cruise objectives were completed safely. In addition, we collected animal specimens from net tows for collaborators associated with the DEEP SEARCH project as well as collecting water samples for eDNA analysis for DEEP SEARCH and other collaborators. Water samples were also collected by a UNH undergraduate in support of her capstone paper. We were fortunate to have good weather for much of the cruise which allowed us to complete additional net tows, CTD, and fine-scale acoustic surveys at some sites (Table 1). We appreciate the excellent work of the ship’s Captain and crew (in all aspects on the boat) in helping us to accomplish our cruise objectives. Table 1. Summary of sampling that occurred at each site location during the EN615 research cruise. We were able to accomplish additional sampling at the VAC and HAT sites.

  • A. Phylum Mollusca Is the Second Largest Animal Phyla After Arthropoda
    a. Phylum Mollusca is the second largest animal phyla after Arthropoda. There are over 90,000 described living species and some 70,000 fossil species. b. Their name comes from the Latin word ‘molluscus’ meaning soft, after their soft bodies. Although in many species, their soft body is protected by a shell. c. Mollusks are a diverse group that range from fairly simple organisms to some of the most complex and specialized of the invertebrates. They include chitons, snails, slugs, nudibranchs, sea butterflies, clams, mussels, oysters, scallops, cuttlefish, squid, octopuses, and nautiluses. d. Mollusks are found in a great range of habitats, although most require water. Only snails and slugs are terrestrial, yet they too are limited in their range by their need for humidity, shelter, and presence of calcium. e. Mollusks are triploblastic coelomate protostome invertebrates. i. While the molluscan coelom is relatively small, the development of the coelom was a major step in the evolution of larger and more complex forms of animals. a. There are seven living classes of Mollusks: i. Polyplacophora 1. Contains 600 species of chitons found on rocky marine shorelines. ii. Gastropoda 1. Contains an estimated 40,000 - 150,000 species of nudibranchs, snails and slugs. Also includes unique species such as limpets, sea hares, sea angel, sea butterfly, and Sea Lemon (pictured above). iii.Bivalvia 1. Also called Pelecypoda; contains 8,000 species of clams, oysters, scallops, and mussels. iv.Cephalopoda 1. Contains 786 species of squid, octopus, nautilus, and cuttlefish. v. Monoplacophora, Aplacophora and Scaphapoda are rare and/or extremely deep-water creatures, and will not be discussed.
