my name is dr. Robert Drew's and I'm chairman of the Department of herpetology at the California Academy sciences Souda Bay and principe are isolated they have never been connected to the mainland if you think about it islands that have never been attached to the mainland anything that lives on them has to cross from mainland Africa across a salt water barrier that's called dispersal and this has happened many many times over many many groups in these two islands South tomei which is only 30 miles long is 13 to 15 million years old the other little one to the north is 31 million years old these two little islands for instance it is thought to have the highest concentration of unique endemic species of birds in the world by unit area it has Giants it has Dwarfs they have a begonia that's five meters tall the other Island has the smallest which is less than a centimeter tall fully in flower the world's largest sunbird the world's largest weaver bird the world's smallest Ibis Africa's largest tree frog all fascinating phenomena that are easy to see on these islands because they're so small there are eight species of amphibians on these islands there should be no amphibians on these islands because they're oceanic they're surrounded by ocean and except for freshwater fish something like a frog would be the last thing you'd expect across a couple hundred miles of Atlantic Ocean to get to these a lot of change is coming there's oil that's been found within their exclusive economic zone there are plans for ecotourism there are plans for an expanded airport a deep-water port all of this is just not going to help the environment at all so we're going to race to find out what's there and then let the people know how special they are before these changes happen if you don't know what it is you're not going to save it well if these kids when they grow up don't realize that the birds they're seeing are found nowhere else in the world not even on the other Island then they're not going to care
