Zoo Rarity: Male Sea Dragon Pregnant

A weedy sea dragon at a Georgia aquarium is giving its handlers a rare Father's Day surprise, the Atlanta Journal-Constitution reports. The small critter—one of only a handful of species in which the male carries the eggs—is pregnant. It's just the third time a weedy sea dragon, whose native habitat in Australia is shrinking, has gotten pregnant at a US aquarium. The new arrivals are due in July.

"I can't even put what I feel into words because it is so rare," said a senior biologist at the aquarium. "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." (More Georgia stories.)
