The Post – Admiral Byrd Kicks Back on Father’s Day With Bubbles

It’s been a while since I’ve done any fiddler crab updates. Just to let you all know, they are alive and well. I’ve been under the weather a lot, so I had to put my attempts to raise babies on hiatus. However, not to worry. I’ll get there yet.

In the meantime, suffice it to say both ladies are doing well and have been mostly hanging out in their live rock. However, I did notice today that one of them was resting in Admiral Byrd’s “lair.” So I suppose babies might be on the horizon again in the not too distant future.

Admiral Byrd decided to celebrate Father’s Day by kicking back and relaxing. He climbed out of the water and sat on top of his cave rock, blowing bubbles. It does have that “foaming at the mouth” look, but in reality, I think he’s just relaxing and aerating his gills while he sits out of water. He keeps moving his claws and legs up and down as if he’s using them to spread the bubbles around and like he’s then washing himself. It does look odd. But, he seemed pretty relaxed.

I came across this entry from Wet Web Media’s FAQ on Freshwater Fiddler Crabs, where someone else noticed the exact same behavior with their fiddler crab, and asked about it:

“Odd freshwater Crab behaviour
I have a ten gallon tank with low water and rocks for crabs and other crustaceans. I bought some crabs and here’s my q’s.
Today the male??, one large one small claw, climbed out of the water onto the rock and started foaming? or bubbling from his face and doing something, like he was washing?? what is this? He the proceeded to sit then later he did this crazy claw dance, waving his arms around slowly in these rhythmic motions all the way out and then back in, what the heck? Does he have mad crab disease?

>> Crabs have to get oxygen when they are out of the water they will “chew” a small amount of water to mix it with air and get oxygen from this process, that is likely why your crab is foaming. He is waving his claws to show his territory and attract females, so he is not mad. …For a great website on crabs and other crustaceans check http://www.crusta10.de not sure if it is all in English, but the site owner is one of the most knowledgeable people on the subject. Good Luck, Oliver”

For some pics of Admiral Byrd’s bubble-blowing session, here you go!

And then from the back…note that Admiral Byrd is still watching me even though I am photographing him behind his back…he has his “eyes” tilted back to watch me:
