Q: Is there more variety among sea- or land-going creatures? Why would one spawn more diversity than the other?
A: There is much more diversity in the ocean than there is on land, even when you compare the ocean to the rainforest. This difference is due mainly to the vastness of the oceans. There are many more niches to fill in the oceans than there are on land. Exploration of the oceans is quite limited. We know more about the surface of the moon, in fact, than we do about the floor of the sea! As we explore our oceans, we discover many new species and habitats. The research that we are doing on this expedition will expand our knowledge and understanding of these vital areas of our world.
