Hi Guys
I found a toad and need some help on ID. Of course it is from the agricultural valley (Yaqui) in south Sonora, MX. If you do not mind to follow my description and correct me please at any mistake. I never saw toad with so much attention on details
Because it has parotid glands== bufonidae
Parotid glands not extending below the level of the tympanum, and at least twice as long as broad
Now, and here is main key, I think that the interorbital cranial crests are well developed, conspicuosly united anteriorly. If this is true then it is an Anaxyrus cognatus..... otherwise I beleive it is an A. woodhousii Distribution good for both
Also, I noted an internal and external metatarsal tubercle black, because it has no light-colored bar across eyelids, it would be A. speciosus but, no good on distribution. Does all Anaxyrus have metatarsal tubercle????
here couple more details
THANKS A LOT IN ADVANCE

Re: ID help on toad
I agree with A. cognatus but it is browner than the ones I usually see.

As well as all the pics I´ve seen. Also on PFG the ID bases on a light color around the black spots, which is not the case here.Chris Smith wrote:I agree with A. cognatus but it is browner than the ones I usually see.

I wonder if there is an adaptation color on this area: Lampropeltis getula nigrita is all black, the Masticophis flagelum cingulum as well. now A. cognatus.... might be a pattern
Thanks for your reply
