Tadpole identification

[UncleChester]

Tadpoles can be tricky to ID, and your picture is too small to be of much help. A higher resolution photo of the above and side views might be useful.

A useful pdf for tadpoles: http://fl.biology.usgs.gov/armi/Guid...dpoleGuide.pdf
And the more thorough North American Key: USGS Patuxent Wildlife Research Center "Tadpoles of the United States and Canada: A Tutorial and Key"

And a list of New England frogs to narrow it down (in case you haven't seen one already) The Frogs of New England: New England Frog Species Information

Colour variations can be tricky in tadpoles, so other clues are usually needed. Like dorsal or lateral eyes. Size of the tadpole. Time of year they were found-> late summer would point to Bullfrog, Green Frog, or Mink Frog. What type of body of water they were found in-> vernal or permanent pond? Scouting the area for adult versions can also be handy (though early spring breeders will often vacate after laying).

Lateral eyes 1 1/2 or 2 1/2 cm found late summer in permanent pond but they seem to small to be bullfrog mink frog or green frog I will get better pic

Bull/mink/green frogs can all take 2 years to morph from the tadpole stage (sometimes 3 for bullfrogs). 1.5-2.5cm would be possible for ones that hatched this year.

I think lateral eyes and your area make it a Gray or a Peeper, with Gray being much more likely given the time of year. Have they started getting leg buds? If it's either of these, they've normally already left the ponds so you'd expect them to morph very soon. Are you positive about the lateral eyes?

No legs yet but there eyes are on the sides of there heads I think that's lateral

Viewing the tadpole from directly above is the easiest way to tell. Handy diagram and description---> North American Tadpoles

Please don't start multiple threads on the exact same topic in multiple forum categories. I've merged them under the 'General Discussion' forum and deleted redundant posts so all the information you've supplied is in one place.

Thanks Brian for the information and extremely useful links . Weird how the first PDF was collated with pages in strange sequence; but the info is great!

You're welcome... and...oops! That's the version for printing double sided and then stapling into a little booklet. Here's a more computer friendly one http://www.cnah.org/pdf_files/430.pdf
