Three critically endangered Burmese star tortoises are pictured May 22, 2008 at the San Diego Zoo, the first time this species has successfully reproduced at the facility. The Burmese star tortoise is not often bred in zoos, but with more as-yet-unhatched eggs, animal care staff is hoping that more of the tortoises emerge. The reptile is almost extinct in its native Myanmar as its numbers dwindle due to deforestation and hunting, both for food and profit. The three tortoises hatched on different days last week.
