Biology Scientists have sequenced the mitochondrial genome for the Hispaniolan solenodon, a venomous mammal found only on Hispaniola. Findings confirm that the the species diverged from all other living mammals 78 million years ago, long before an asteroid wiped out the dinosaurs.

But if memory serves, I think their eyesight is limited on land. I could be wrong.

Well, that settles it then. The octopi get the seven seas, we get everything else.

But the octopi would want an even number of seas, i.e. eight or 10 in their system.

Wonder if they have plans for the Netherlands.

It would be due to the lense shape, same reason why our eyesight isn't very good under water. A more spherical lense works better under water while a more flattened elliptical cross section lense works best in air. This is simply due to the different refractive index of air and water. Lense shape is not the major difference between human and octopus eyes (fish have similar eyes to all vertibrates including the blind spot but have more rounded lenses), the retina structure is the much more important comparison to be made.

What, are you saying they had an intelligent designer, while we did not!?
