About agalma, there is a significant size difference between the Juarez population and the San Pedro Martir population. The latter is much smaller in average. I recently read that the two probably will be divided taxonomically pretty soon since DNA testing shows that they are really not that alike. Brian Hubbs states that DNA results indicate that the San Pedro Martir kind might even get to be a separate species.

My largest agalma was 34 inches when he died last year.
