Next message: Journey North: "Challenge Question #1"
One reason why Mexico's lagoons make such good whale nurseries is
because the warm waters of the shallow lagoons help newborn babies,
which are relatively blubberless, conserve body heat. Also the gray
whale's predator, the orcas, do not care for the shallow water and
narrow entrance of the lagoons. As a result the gray whales have an
advantage over them. Since the lagoon's entrances are narrow and there
are many sandbars, only very experienced boaters can drive through the
area. Without many boaters the whales benefit because they have more
space and don't have to worry abut watching out for anything that can
harm them or their young.
