Here is a link to a nice article by Chester Moore Jr. of the Port Arthur News. In the article Moore mentions several rare and elusive species such as the margay, long-tailed weasel, grizzly bear, and manatee.
Moore doesn't mention anything about cryptids but I have to believe he would have liked to. Moore is the author of several books about bigfoot inlcuding Bigfoot Lives: Deal With It and has appeared on several bigfoot themed television shows such as Animal Planets' Animal X program. He has also delved into the black panther mystery and believes the jaguarundi is a likely candidate for at least some of the sightings of these large black/dark cats.
He is an interesting guy. Check out his article.
