Well, that is life for you. One minute you’re choking in the ER, the next maybe we’ll be surrogate grandparents for our fiddler crabs?
Again, it is my husband, the one who made fun of my fiddler crab project, who notices changes in the fiddler crab tank.
We have noticed Scarlett O’Hara on occasion, seeming interested in Admiral Byrd. Admiral Byrd of course, ALWAYS waves his claw even when no one is around. My husband explained this is a guy thing – you always stand around looking cool, just in case. Well, apparently things happen when the lights go out.
For the last 2 days my husband has mentioned, with concern in his voice, that Scarlett O’Hara has been climbing all the way up the water filter, almost to the top of the tank, and has been hanging out up there. We just thought she wanted to be queen of all she surveyed and liked being up high.
Today he looked at her and said: “I think Scarlett is going to have babies! Do fiddler crabs carry their eggs on their abdomen?” I glanced at her and there was this wad of brownish spongy stuff tucked against her abdomen, underneath her mandibles.
Sure enough, a glance at a web site of the Fiddler Crab Life Cycle, shows pictures of pregnant females carrying hundreds of thousands of fertilized eggs on their abdomen. The pictures look just like Scarlett O’Hara. So, she’s pregnant!!!!
Now my understanding from something I read, was that female fiddler crabs burrowed down into the sand 23 inches or so, to lay their eggs. So I felt assured we would not be contending with “babies.” In fact, maybe that’s why Scarlett’s been climbing on top of the water filter. Maybe she’s been looking for someplace deep to lay her eggs.
However this same website on the fiddler crab life cycle indicates that female fiddler crabs RELEASE their fertilized eggs into the water and they float around as plankton. When they molt and get big enough, then there’s JUVENILE CRABS running around the tank.
My husband’s reaction was almost identical to 20 years ago when I invited him to have lunch with me at the hospital one weekend when I was working, so I could tell him the results of a certain pregnancy test I had just run: “Oh my God.” My husband said, “I’m not ready to be a grandfather yet, especially to a few hundred thousand fiddler crabs . . . ” But you and I both know, if there’s babies in the tank, he’ll be watching over them and concerned about them.
Now another site I found, About.com’s Keeping fiddler crabs as pets, (which by the way is a GREAT summary of how to raise fiddler crabs in general AND has instructions on setting up a brackish water tank) indicates it’s near to impossible to raise the babies in captivity. Apparently the babies need to go out into deep ocean water to grow then return to the brackish water estuary when they are older.
Well we shall see. Who knows? We may yet have BABIES in the tank!!!!! 🙂 So, the $4 fiddler crabs, with the >$100 of support gear so I could establish a brackish water tank so they wouldn’t die, have apparently not only not died, but thrived! Now we may need ANOTHER TANK so the thousands of babies have a home. Anybody want to buy some fiddler crabs? I’ll keep you posted on the progress of the pregnancy.
Stay tuned this week for pictures of the pregnant mom!
