Below is an international list of wildlife parks and zoos by continent that currently have a mustelid exhibit. This PDF list is unlikely to include all zoos that hold mustelids, and is subject to change more than we’re reasonably able to update, since animals are often relocated.
Due to charismatic megafauna, otters are by far the most common mustelids held in zoos and wildlife parks. Although otters are wonderful animals, it can be frustrating for people who are interested in seeing other mustelids, and this list is to primarily help with that search.
Disclaimer: If you plan to visit any of the listed wildlife parks or zoos to see a particular mustelid, it is recommended you contact their office for confirmation on current exhibits, as these exhibits do frequently change.
