Here's a beautifully decorated Louis Comfort Tiffany gold Favrile vase with green pulled tadpoles and white opaque glass threading.  Absolutely mint condition, fantastic coloring on the gold Favrile, truly an amazing and rare L.C.T. vase. 

The tadpoles alternate around the vase (there are six total) with every other one starting 1/3 the way down, with the tail extending to the pontil, and then every other one starting towards the neck of the vase, with the tail ending on the last line of opaque white threading.  A very unusual Tiffany vase for sure.

It's signed "o4063" as seen in the picture above, indicating that it's a special order piece (as indicated by the letter o (not zero), making it a much less common piece, as it's a one of a kind.  We typically see L.C.T. tad pole vases, drinking vessels, decanters, etc., in gold Favrile with gold Favrile tad poles, yet this one has iridescent green tadpoles applied on a gold Favrile vase with white opaque glass threading. 

For similar Tiffany pieces, see "Behind the Scenes of Tiffany Glassmaking: The Nash Notebooks" page 223, second row, fourth item. It's interesting to note that they indicate that the pages shown from this catalog were made for the German market.

Also see "Tiffany Favrile Art Glass" by Moise S. Steeg which shows several tadpole pieces, but only a few that incorporate the tadpoles and threading. Take a look at page 9, the top picture of the lily pad piece. Also page 126 has a gold Favrile threaded glass with similar tadpoles (and apparently alternating tail lengths).

Please rest assured this piece is guaranteed to be correct and an authentic piece of Louis Comfort Tiffany Glass (buyers please be careful, as there are frequently L.C.T forgeries on eBay).
