@futurebird one of my favorite examples of an interctive key is this one for snails and slugs in the US. https://idtools.org/tools/1075/index.cfm It's point/click, has visual examples, and also the name. Terrestrial Mollusk Tool (yep it sure is). It's also interesting in that it's designed for use by people who might not be familar with dichotomous keys/versed in mollusk taxonomy.
