A dark iris makes it difficult to distinguish the pupil from its background in a live snake. The attribute <i>"indistinguishable"</i> is just additional information. The pupil shape has to be determined seperately.<br>

This attribute is only visible in the pupil references of snakeDB. On all other pages, it is filtered out.
