Scanning electron microscopy of the poison glands of Taricha granulosa from LW− and SC+ populations. (a) In the LW− population, Type I cells have two types of granules, a smaller one with a dense appearance (*) and a larger one with a flocculent appearance (#). (b) In the SC+ population, Type I cells exhibit only flocculated granules. (c) In the LW− population, granules of Type II cells are spherical and show a smooth surface. (d) In the SC+ population, Type II cells are similar to those of the LW− population. Sexes of the animals: female (images a–d).
