Tadpoles and recently-metamorphosed terrestrial juveniles
The following spadefoot tadpoles and metamorphs were photographed at several locations in Cochise County, Arizona, where Spea multiplicata and Spea bombifrons both occur. These spadefoots could be either species. I cannot positively identify them at such a young age and small size, other than saying that most likely they are not Scaphiopus couchii, so I will just say that these pictures probably include individuals of both species of Spea.

A spadefoot calls at night while floating on top of a flooded pool in a wash in Hidalgo County, New Mexico. When another male comes close he makes a different snoring sound and swims around. Other spadefoots and Western Green Toads are heard in the background. A tiny recently-metamorphosed spadefoot (either Spea bombifrons or Spea multiplicata) which has not yet absorbed its tail hops around next to its dessicating breeding pool with a predator attached to its tail (probably a water scavenger beetle larva.) Cochise County, Arizona. Spadefoot tadpoles swim around in a small aquarium. Cochise County, Arizona.

These are tentatively identified as Spea bombifrons, but there is a chance they could also be Spea multiplicata (stagnalis.)
  Spadefoot tadpoles (either Spea bombifrons or Spea multiplicata) in a rain pool in Cochise County, Arizona metamorphose into tiny tailed spadefoots and move onto land as the pool quickly drys up. (Shown over a period of about one week.)
