mexican lance headed rattlesnake chapultepec zoo

Never heared of and never seen ! Is it kept ( or even bred ) in other collections ?

The Los Angeles Zoo has some on exhibit in the LAIR. I'm not sure if they have been bred at the zoo.

This species is new at Chapultepec. I had bever seen it before, which is why i took the photo and posted it here. There were a pair of these beautiful snakes.
It should be mentioned that LA zoo really does a fine job of breeding and exhibiting various different mexican species.

abq biopark has them. not sure if they've bred there, though.
