Rare Sea Dragon Is Pregnant

A weedy sea dragon at the Georgia Aquarium has something to celebrate this Father's Day. One of the rare creatures is pregnant for only the third time ever at a U.S. aquarium, aquarium officials said. But don't look for the expectant mom -- dads carry the eggs in this family

The aquarium's sea dragon has about 70 fertilized eggs -- which look like small red grapes -- attached to his tail. He is expected to give birth in early to mid-July, said Kerry Gladish, a biologist at the aquarium.


Sea dragons, sea horses and pipe fish are the only species where the male carries the eggs, Gladish said. Sea dragon pregnancies are rare because researchers don't know what gets them in the mood to mate.


"We know there's something biologically or environmentally that triggers them to want to reproduce, but in the aquarium world, we're not sure what that is," Gladish said.


The aquarium recently changed the lighting and thinned out the plants in the sea dragons' tank to give them room to court each other.


The aquarium has seven of the 18-inch sea dragons, which resemble Dr. Seuss characters with long aardvark-like snouts, colorful sea horse bodies and multiple paddle-like fins.

During mating, the female lays dozens of eggs and then transfers them to the male's tail.


In the wild, the survival rate for sea dragon babies is low, but in captivity it's about 60 percent, Gladish said. The fish is on the International Union for Conservation of Nature's list of threatened species, mostly because of pollution and population growth in its native Australia.


Only about 50 aquariums worldwide have sea dragons.

The Mating Game


We have a pair of 8-year-old Darwin (black and white) Ocellaris Clownfish in the company's main display tank that lay eggs every couple of weeks or so.

I've been with the company just over a year now, and they spawn like clockwork.

The male has very little orange coloring and the fe
male has none, so their offspring may be very unique.

A couple of our staffers reached out to Bluewater Aquaculture to see if they were interested in raising the hatchlings, since we're not equipped to do so here in the office.


The first batch off eggs they took to their facilities were laid on the side of a clam. Unfortunately, they did not have the best luck harvesting them.

Bluewater recommended putting a piece of tile in the display tank so the clowns would opt for it instead of the clam. At 5 PM last Saturday, they did just that.

If you're wondering why I'm only giving a roundabout explanation of all the goings-on, it's because this whole process is documented on Bluewater Aquaculture's own blog.

I've included some photos that Steve, head of our livestock division (MarineDepotLive.com), shot last week.

Enjoy!
