Identification of Incilius luetkenii (a yellow toad; deformed here) tadpoles has been difficult;  the species has only been recently defined, and no description of the tadpole was available before Savage’s key was constructed, so there I. luetkenii is no in the key.  The tadpole keys to Chaunus marinus (the marine or cane toad) , but given the reduced number of C. marinus here compared to I. luetkenii, we think the tadpoles below are the latter.  This is, of course, one of the reasons Mahmood is rearing the tadpoles.  It seems to be going well though as evidenced by the metamorph photographs below!

The tadpole is medium sized to small, and appears dark, making it difficult to photograph.  The oral disk is emarginate, and the mouth has 2/3 denticles, with the second anterior denticle having a medial gap.
