    World's Smallest Snake

    By Posted on 8.4.2008 7 Comments

    An evolutionary biologist at Penn State University has discovered a species of snake so small that it can fit comfortably on a quarter. The average adult of the species, a type of threadsnake named Leptotyphlops carlae, is less than four inches long. The discovery will be published in the August 4 issue of the journal Zootaxa.

    ----------------------- The Barbados Threadsnake only occurs on Barbados. What people in Florida and other places (Hawaii, other islands in the Pacific, California, Texas, South America, Africa, etc.) are seeing is a common introduced species, the FlowerPot Blindsnake, Ramphotyphlops braminus, that belongs to a different family (there are other species as well, but this one is common around houses). It was introduced probably from Indonesia. It is BLACK and very thin. The hatchlings and young can fit on a coin, but the adults are larger than the adults of the Barbados Threadsnake (the Flowerpot Blindsnake also occurs on Barbados). The two are not the same species for the same reason that not all small birds or small mammals are the same species (There are 3,100 species of snakes). Different species often have characters that must be seen under a microscope. Often, their sex and adult status can only be determined by an expert. Use internet searches to determine what you have, and to learn more about the species that occur in your area.

    Readers Ask: How Can I Tell If I've Found A New Species?

    By Posted on 8.14.2008 6 Comments

    Several Florida residents have reported seeing the Leptotyphlops microsnake long before it was announced as a new species, which herpetologist Blair Hedges named for his wife. Readers want to know: how can you tell if the new animal or plant you've stumbled across is a unique, as of yet unnamed species? Do you know the answer?
