Underwater Field Guide to Ross Island & McMurdo Sound, Antarctica Want List of Images

I am interested in receiving images of these McMurdo Sound organisms for review for incorporation into this Field Guide. The best images are sharp, properly exposed, with the organism filling at least half of the frame.

Thank you, Peter

• Sponges
  • sponge Asbestopluma aff. lycopodina: would also like a macro showing it trapping/consuming crustaceans
  • root sponge Rossella racovitzae: need good images of different morphs
  • vase sponge Rossella nuda: need images of smooth morph only
  • cone sponge Polymastia invaginata: need full frame shots
  • pipe or chimney sponge Rossella fibulata: would also like location/depth info to document its distribution
  • cerithiopsid gastropod Krachia antarctica found at the base of Haliclona dancoi, where it grazes on the sponge for food
  • any species not in the Field Guide

• Cnidarians
  • siphonophores
  • ctenophores
    • EXCEPTION: don't need Beroe
  • salps
  • small-sized jellyfish species -- don't need the big jellyfish species commonly seen, unless it is a species not listed in the Field Guide
  • anemones: need to see trunk as well as tentacular crown in photos.
    • EXCEPTION: don't need Artemidactis victrix
    • EXCEPTION: don't need Isotealia
    • EXCEPTION: don't need Urticinopsis
  • hydroids: all species; need identifications for these to be useful
  • nephtheid soft coral Gersemia antarctica: need shots of it in Ross Island locations, with location and depth information, in order to record its distribution

• Molluscs
  • all chitons
  • great nudibranch shots
    • EXCEPTION: don't need Doris kerguelensis
  • notaspidean opisthobranch Bathyberthella antarctica
  • cerithiopsid gastropod Krachia antarctica found at the base of Haliclona dancoi, where it grazes on the sponge for food
  • Antarctic yoldia Yoldia eightsi (yellow olive colored clam)
  • macro closeup of shell of adult Antarctic scallop Adamussium colbecki, showing juvenile scallops and tiny hydroids attached to adult's dorsal shell
  • shelled pteropod Limacina helicina antarctica
  • other Marseniopsis species
    • EXCEPTION: don't need M. mollis

• Annelids / Polychaetes: all species,
  • EXCEPTION: don't need Flabelligera mundata
  • EXCEPTION: don't need Perkinsiana sp.
  • EXCEPTION: don't need Chaetopterus

• Bryozoans: all species; need identifications for these to be useful

• Brachiopods: all species

• Arthropods
  • Sea spiders: only those not in the Field Guide or poorly represented in the Field Guide; need heads/bodies in clear focus

  • Crustaceans
    • Adult Caecognathia calva on hexactinellid sponges [look on Rossella spp. or Anoxycalyx (Scolymastra) joubini] with a single male close to the oscular opening, accompanied by a harem of several breeding females and also some juveniles
    • Santia charcoti, a one millimeter long isopod, widely distributed on the body surface of Haliclona dancoi, probably grazes on the sponge, its presence can be used to identify H. dancoi from other similar sponges
    • macros of amphipods and isopods,
      • EXCEPTION: don't need arcturid isopods
      • EXCEPTION: don't need giant Antarctic isopod
    • shrimps
    • tanaids
    • ostracods
    • krill: need sharp macro shot with good depth of field
    • barnacles

• Echinoderms
  • Asteroids
    • seastar Cuenotaster involutus
    • seastar Lophaster gaini
    • seastar Porania antarctica glabra
    • seastar Psilaster charcoti
    • asteroid species not in the Field Guide

    • any brittle star species not in the Field Guide
    • sea cucumbers / holothurians: all species
    • macro photo of the underside of the pencil urchin Ctenocidaris perrieri with brooding juvenile urchins. These juvenile urchins will be up to five millimeters in size and are located smack dab in the middle of the urchin's underside, on the membrane covering that hole going into the urchin shell (called the peristome)

• AND ......

  ANY SPECIES NOT in the FIELD GUIDE
