  1. WHOA! Very cool, very wonderful shots of the worm. Family Acoetidae (in older books as family Polyodontidae) - the scales and the stalked eyes are a dead giveaway. I've never seen shots of one alive. Normally they are in tubes buried deep in the sediment or under rocks. So 2 questions - where/how did you find it, and (you knew this one was coming) could I possible have high res versions with your copyright shifted so it doesn't obscure the features? Pretty please? Pretty please on my knees begging?

  2. Hi there -

    The first is in either genus Acanthozoon or Thysanozoon. There's a whole suite of species with this general appearance and it's hard to tell which is which.

    Second is a fireworm in the genus Chloeia.

    Third I'm not sure about but the reticulated pattern & shiny skin make me think it's a sipunculid worm.

    Fourth is a polychaete, family Sabellariidae. Someone once sent me one of these which I passed on to a specialist. He thought it was a new genus but others feel it belongs to the genus Lydgamis. The two appendages are soft feeding structures fringed with filaments which capture food particles from the water.

    Fifth is usually identified as Protula magnifica in the guide books.

  3. It's a nemertean. The big ones without distinct color patterns are hard to identify. Important characters necessary for identification include details of the head like position & shape of the mouth, lateral slits, etc. Unfortunately none of these show in you picture, sorry!

  4. Thanks guys. I figure 90% of usage for my camera is on the microscope, 5% on a camera stand with the mpe-65 and 5% regular shots so working distance isn't a big consideration. James recommended a Rebel too, the Xsi, so I'm going to take a look at that. Having live view for scope work is a real plus.

  5. My canon 5D is clearly overkill for my primary use - macro through a dissecting microscope. I hardly use any of the functions and it's too big & heavy for my current set-up. It's time to sell or swap it for something else. Any suggestions for something smaller and lighter? I want to stick with canon as I love my MPe-65 lens.

  6. It's a pelagic snail in the family Carinariidae. There's at least one IP species that has brown pigment along the tail - Carinaria cristata - so it may be that. Pelagic snails are pretty fantastic. Shells are reduced or even absent while bodies are translucent to completely transparent. Usually the only parts visible are the eyes, mouth parts, and stomach areas. They're voracious predators of other pelagic critters such as salps, chaetognaths, and other snails.





  7. Hi Anne -- You've got me stumped on this one. Not a nemertine, doesn't resemble any of the sipunculans I know for the area, maybe a mollusc siphon????? Hopefully Jon the Nemerterminator will catch this thread. Anyone else know?
