Judy, 1.) Blue whales have a single calf arial,helvetica(at about twenty five feet and three tons, that is still a pretty big baby)... <<<<<<<< 2.) Well, the most common estimates are about seven or eight months of nursing. The assumption is that at that point the calf is weaned. I do not know for sure how long a calf might remain close to it's mother (most estimates are that the calf will put on about twenty tons of weight while it is being nursed...whew). ge >>>> arial,helvetica At 05:59 PM 1/24/01 EST, you wrote: >>>> arial,helveticaDear Greg: My daughter is doing a project for school and needs the answer to the following two questions: 1. How many calves may be born to a Blue whale at a time 2. How long do the calves remain with the mother before being weaned? We appreciate your help. Thank you. Judy Serrapica arial,helvetica
