Wildlife of the Day (Episode 2)


Some sea-surface organisms found in one of last night's box cores.
These turned up in a box core last night. The core was taken at a depth of about 60 m. We're not sure what the long-stemmed things are, but Dale is working on it.

Yes, that is the same Dale who came through with the identification of our "acorn worm" -- see his comment below in the first episode of Wildlife of the Day. Dale is one of the long-core guys. He has a degree in Marine Biology (from Texas A&M Galveston), is currently working at Oregon State, and is, obviously, curious about all things biological.

When Dale split open one of the long-stemmed organisms and looked at it under the microscope, he said it contained spicule-like objects. Could these be sponges of some sort?

If you can identify these, please send us a comment. Although this is, primarily, a geological (paleoclimate) cruise we love learning about everything we come across out here.

  1. Current best guess (courtesy Dr. Don Harper, emeritus professor of invertebrate zoology from TAMUG) is that these are some sort of Pennatulacean, the same order which contains sea pens and sea pansies. Some pennatulaceans have spicules...

  2. Thanks Dale. I think I'll go read up on Pennatulacean now!
