Beavers can stay underwater for up to 15 minutes without surfacing. Their large lungs store extra oxygen, and they slow their heart rate to conserve it.

Today, we celebrate International Beaver Day! Established in 2009 by Beavers Wetlands & Wildlife, this day highlights the vital role beavers play in our ecosystems. Beavers are remarkable creatures known for their dam-building skills, which create wetlands, benefiting numerous species. As North America's largest rodents, they can grow up to 3 feet long, not including their distinctive flat tails. Their continuously growing teeth, with thick enamel giving them an orange hue, are essential tools for gnawing on trees—a behavior that maintains both their dental health and their environment. No wonder their strong choppers make them one of nature's best engineers. Who knew a furry little architect could have such a big impact on nature?
