Difficult to see from a smallish image ;-).
e) might be an Echiuran and c) and d) Sipunculans. I Assume they are U.S. species?
I think Hans has it right. If from the Pacific coast look at Lights (revised) Manual, it is very helpful and it may be possible to get a generic name.
can you post larger pics, and a scale of each one? the two on the top are (left) an Echiuran, (rigth) is probably an Hydrozoan polyp. The two gems might be a future medusa, and a sporosac, ut it is hard to tell with such low magnification. Those in the midlle are a a sipunculid on the left, and the one on the right could be a priapulid. On the bottom: hard to tell the external ornamentataion, but if the one on the left is freshwater, is a bdelloid rotifer, if it is marine, and microscopic, is a Gastrotricha. The one on the right seems like some kind od Coelenterata (a jelly fish). If you post the pics one by one, you might get a better help!
a) sipunculans (Looks similar to Thysanocardia sp.); b) may also be a sipunculan but difficult to tell from the image; c) possibly a Caudofoveate but poor picture; d) Caudofoveata but can't go any better than that; e) Echuira; f) Ascidiacea?
II agree with Christopher: a and b look like sipunculans, d is caudofoveata, d seems an echiurid and d a small colonial ascidian. As for c, the quality of the image is very bad, but the ornamentation lead me to think that it may also be a sipunculan (maybe a fragment).
Specimens in fig. a and b belong to sipunculans; specimens in Fig.a may be a species of Onchnesoma. Fig.c could be a species of flabelligerid polychaete worm, but should be checked if it has chaetae or not (not seen in the figure). Specimen in Figd belongs to Caudofoveata. Fig.e could be a fragment of any species. Fig.f could be a species of Ascidiacea
Dear Naidu
If you would like to make your sipunculan specimens identified, you could contact with Dr. Sermin Acik ([email protected]) who has experiences on the Indo-Pacific species.
Dear Melish thank you very much for your kind suggestion, sure I can try that.
These are probably the egg cases of an intertidal gastropod, judging by the photo.
The answer of Paul Sammarco does not refer to this question. As to the 6 photos of this question: I strongly support the answer of Christopher Ashelby.
Good Morning Godfried,
I think these resemble siphunculids and are unlike tunicates. I will have found specimens like these in deep water muds and in intertidal pools. Their colour is quite noticeable and I would think there is someone out there with better expertise than I who could give a species ID. Nice and interesting pictures. All the best
