    Challenge Question #8
    "Why do you think that mainly adult manatees died from red tide and not young manatees?"

    From: COLORADO
    The young manatees are nursed, and they do not rely on plants as much as adult manatees do. It also might eat a plant that is not as much affected with the red tide then some of the other plants. We are from Crested Butte CO.

    Answer: I think it was mainly adults that died because the young manatee's central nervous systems aren't fully developed yet. If their central nervous systems aren't developed yet the dinoflagellates in the red tides can't harm them.

    Third graders from Ferrisburgh Central School think that the red tide makes a poison that is stored by the manatees. The more times, the manatees are exposed to the red tide, the more poison in the body. The older manatees already have some poison in their body and so get sicker easier.

    The adults stay under longer and the younger manatees don't have as developed central nervous system, so I would think the adults would be more exposed more.
