  • MARINE TANK GUIDE About the Marine Tank
    HOME EDITION MARINE TANK GUIDE About the Marine Tank With almost 34,000 miles of coastline, Alaska’s intertidal zones, the shore areas exposed and covered by ocean tides, are home to a variety of plants and animals. The Anchorage Museum’s marine tank is home to Alaskan animals which live in the intertidal zone. The plants and animals in the Museum’s marine tank are collected under an Alaska Department of Fish and Game Aquatic Resource Permit during low tide at various beaches in Southcentral and Southeast Alaska. Visitors are asked not to touch the marine animals. Touching is stressful for the animals. A full- time animal care technician maintains the marine tank. Since the tank is not located next to the ocean, ocean water cannot be constantly pumped through it. This means special salt water is mixed at the Museum. The tank is also cleaned regularly. Equipment which keeps the water moving, clean, chilled to 43°F and constantly monitored. Contamination from human hands would impact the cleanliness of the water and potentially hurt the animals. A second tank is home to the Museum’s king crab, named King Louie, and black rockfish, named Sebastian. King crab and black rockfish of Alaska live in deeper waters than the intertidal zone creatures. This guide shares information about some of the Museum’s marine animals. When known, the Dena’ina word for an animal is included, recognizing the thousands of years of stewardship and knowledge of Indigeneous people of the Anchorage area and their language. The Dena’ina & Marine Species The geographically diverse Dena’ina lands span both inland and coastal areas, including Anchorage.

Loricifera Acknowledgements Glossary Bibliography Biographical Sketch Summary UNESCO – EOLSS This chapter provides information on several basal bilaterian groups: flatworms, nemerteans, Gnathifera,SAMPLE and Nemathelminthes. CHAPTERS These include species-rich taxa such as Nematoda and Platyhelminthes, and as taxa with few or even only one species, such as Micrognathozoa (Limnognathia maerski) and Cycliophora (Symbion pandora). All Acanthocephala and subgroups of Platyhelminthes and Nematoda, are parasites that often exhibit complex life cycles. Most of the taxa described are marine, but some have also invaded freshwater or the terrestrial environment. “Aschelminthes” are not a natural group, instead, two taxa have been recognized that were earlier summarized under this name. Gnathifera include taxa with a conspicuous jaw apparatus such as Gnathostomulida, Micrognathozoa, and Rotifera. Although they do not possess a jaw apparatus, Acanthocephala also belong to Gnathifera due to their epidermal structure. ©Encyclopedia of Life Support Systems (EOLSS) BIOLOGICAL SCIENCE FUNDAMENTALS AND SYSTEMATICS – Vol.

  • I FLATWORM PREDATION on JUVENILE FRESHWATER
    FLATWORM PREDATION ON JUVENILE FRESHWATER MUSSELS A Thesis Presented to the Graduate College of Southwest Missouri State University In Partial Fulfillment of the Requirements for the Master of Science Degree By Angela Marie Delp July 2002 i FLATWORM PREDATION OF JUVENILE FRESHWATER MUSSELS Biology Department Southwest Missouri State University, July 27, 2002 Master of Science in Biology Angela Marie Delp ABSTRACT Free-living flatworms (Phylum Platyhelminthes, Class Turbellaria) are important predators on small aquatic invertebrates. Macrostomum tuba, a predominantly benthic species, feeds on juvenile freshwater mussels in fish hatcheries and mussel culture facilities. Laboratory experiments were performed to assess the predation rate of M. tuba on newly transformed juveniles of plain pocketbook mussel, Lampsilis cardium. Predation rate at 20 oC in dishes without substrate was 0.26 mussels·worm-1·h-1. Predation rate increased to 0.43 mussels·worm-1·h-1 when a substrate, polyurethane foam, was present. Substrate may have altered behavior of the predator and brought the flatworms in contact with the mussels more often. An alternative prey, the cladoceran Ceriodaphnia reticulata, was eaten at a higher rate than mussels when only one prey type was present, but at a similar rate when both were present. Finally, the effect of flatworm size (0.7- 2.2 mm long) on predation rate on mussels (0.2 mm) was tested. Predation rate increased with predator size. The slope of this relationship decreased with increasing predator size. Predation rate was near zero in 0.7 mm worms. Juvenile mussels grow rapidly and can escape flatworm predation by exceeding the size of these tiny predators.
