Aquarium teaches adults "Motions of the Oceans"

The Georgia Aquarium is putting a different — and decidedly adult — spin on Valentine's Day this year.

In a special sleepover open to the over-21 crowd, the downtown attraction plans to show why it's not only the world's largest fish tank — it's also the world's largest underwater mating den.

In "Motions of the Oceans," married aquarium biologists Al and Patricia Dove will discuss the secret mating rituals, otherwise known as "Everything I wanted to know about what fish do when the lights are out but was afraid to ask."

If you're a male squid, that nocturnal bliss might be — how does one say this delicately — transferring your seed to your female partner via a modified tentacle. Or, for female sharks, it could be reproducing without male sharks at all.

And, of course, the Doves will explain, ahem, when and why size matters.

Food and drink — such as kumomoto oysters — from Wolfgang Puck Catering will be included.

The event comes on the heels of a number of programs the aquarium has offered to lure visitors. The attraction introduced the Titanic Aquatic exhibit late last summer and recently announced yoga classes.

The Valentine's Day sleepover begins after the lecture, with visitors spending the night in the Ocean Voyager Gallery.

Prices for the lecture and dinner are $85 for nonmembers and $75 for members. The cost of the lecture, dinner and sleepover are $160 for nonmembers and $135 for members. For more information, go to www.georgiaaquarium.org or call 404-581-4000.
