The region Stephen McCullah, the organizer of the expedition, has chosen to explore is the reputed home of the Mokèlé-mbèmbé, a dinosaur-like creature said to be up to 35 feet long (11 meters), with brownish-gray skin and a long, flexible neck. Many locals believe that it lives in the caves it digs in riverbanks, and that the beast feeds on elephants, hippos and crocodiles.

I'm all for finding the undiscovered species that are waiting to be found in the Congo, but I think the Mokele-mbembe is a myth. I think we would have seen some evidence of its existence by now.
Finding a spider the size of a dog would be remarkable enough, as the largest-known tarantula, the Goliath birdeater, lives in South America and has a leg span of "only" a foot.
Only a foot? I would be running in the other direction if I came across that giant spider.
