Have you ever heard a bullfrog scream?

One of the most memorable experiences I had as a teacher intern last spring was an ecology class field trip to a vernal pool near my home. The kids were fully engaged, and several of the boys were determined to catch as many frogs as they could. One of the frogs that was scooped up was the ornery little bullfrog in the video below – despite spending much of my academic career as a frog researcher, I’d never heard a bullfrog alarm call before. This guy had everyone quite entertained with his screeching!

I'm a recovering academic, current high school biology/zoology teacher, blogger, and science geek with diverse interests (and experience) in the areas of zoology, anatomy, evolutionary biology, developmental biology, and exercise science. I made the fairly unusual jump from higher ed (10 years, including tenure, as a college biology professor) to teaching high school biology at Coe-Brown Northwood Academy in Northwood, NH. In addition to being a dedicated teacher, I'm also an avid distance runner - I write about running at Runblogger.com. You can follow me on Twitter, Facebook, Pinterest, Instagram, and Google+.
