Mating Oxynoe antillarum

February 18, 2010
From: Michael Davis

Note added 18 Feb 2010: On the basis of the egg size, Kathe Jensen considers this is most likely Oxynoe azuropunctata [see message #23250]

Concerning message #22618:

Hello,

I currently have a handful of Oxynoe antillarum most likely Gulf of Mexico strain. They appear to be fond of my Caulerpa mexicana that I got in a recent Macro order. I have been witnessing courtship behaivor and have spotted several egg masses. I have counted atleast 8 of them so far. Is there any information on life span?

Dear Michael,

I am not sure if their lifespan has been studied but if it has I am sure Kathe Jensen will be able to help out. Most of these species have a short lifespan of less than a year. If you are thinking of breeding them from the eggs, this could be difficult, as it is usually very difficult to keep the larvae alive.

Best wishes,
Bill Rudman

Dear Michael and Bill,

The egg capsules on Michael's photos look more like those of Oxynoe azuropunctata. The capsules seem to be large relative to the eggs/embryos, which indicates lecithotrophic development. Do you have any idea about the size of the individual egg capsules? In O. azuropunctata they could be almost half a millimeter in diameter. With lecithotrophic development the animals could have been just egg masses on the algae when they were collected.

I don't know about life span of any Oxynoe (or most other sacoglossans). I usually collected only the number of specimens I needed for my experiments, and after that they did not die of old age.

Larval development in O. azuropunctata takes about 4 weeks, and the larvae are able to crawl about on the algae right away though they do have a small velum for swimming. This is lost a few days after hatching. It would be fun to know if you suddenly have Oxynoe babies in your aquarium.

Best wishes,
Kathe

Thanks Kathe,

If anyone has a clear photo of O. azuropunctata we could add to the Forum I would be very grateful

Best wishes,
