Big Bertha---collected May 17, 1983 as a large 1-2 year old neotone from White Ledge Tank on the San Carlos Apache Reservation. She metamorphosed in the lab and is now 25+ years old and is probably among the oldest Arizona tiger salamanders in captivity (or in the wild). Eats one neonatal mouse per week.
