    Dear Colleagues at the Woods Creek School ,

    I was quite pleased to receive your fine letter. The questions posed are
    clear and direct.

    1) I have consulted the IUCN Redbook and the NatureServe Explorer. The blue
    whale is listed as vulnerable in some areas and secure in others. The North
    Atlantic stock is vulnerable and is estimated at 1500 individuals. The
    Pacific and Southern Ocean populations are estimated at 10.000 individuals.
    That is a total of 11'500 animals.

    2) The blue whale has at this time only one enemy the killer whale. Hunting
    blue whales by people is illegal and has stopped for all intents and
    purposes. Killer whales are opportunistic predators and as such help keep
    the bulk of the blue whale population healthy.

    3) The mother whale nurses the calf for one year. This is sufficient time
    for the calf to learn how to feed itself. Blue whales form large pods . The
    calves tend to remain associated with those herds for long periods of time.
    Perhaps for their entire lives. It is estimated that blue whales may live
    for 80 to 90 years.

    4) Blue whales have one calf every three to four years.

    These were excellent questions and are the type of questions that good
    science is based upon.
    Please keep your interest in fact finding questions throughout your school
    years. You will all find that the search for complete answers is quite a bit
    of fun.

    Thank you for this opportunity to help your learning experience.

    Dr. Tom Ford

    >> Dear Online Scientist,
    >> We have been studying the amazing Blue Whale. We have a few questions
    >> about Blue Whales that we'd like to ask an expert. How many Blue Whales
    >> are living in the ocean today? We would also like to know if the Blue
    >> Whale has any enemies? We were also wondering how long cows stay with
    >> their calves and how many calves do they have? We would love to hear back
    >> from you and thank you for your help!
