Currently, there are thirteen species of otters worldwide. All of them are monitored and five of the thirteen are endangered. World Otter Day (International Otter Awareness Day) is a day to celebrate otters around the world. Held on the last Wednesday of May, you can spend the day visiting otters in the zoo, reading about otters, or donating to the International Otter Survival Fund. Here at Otter Things™, I decided to release a new design for the otter fan.
