I had to watch the video twice...

The first time I was just admiring the human.
The second time I noticed the snake.





Great video.

Lucky kids to have a biology teacher like you! Most of the biology teachers I know do not do field herping/practical stuff much. They usually stick to the textbook. My biology teacher (I went to high school in the Philippines) took us out on a field trip to the beach on a coral reef island and we gathered specimens of stuff we found - both plants and animals, in the water or on land - and identified kingdom/phylum/class/order/family/genus/species, etc... that was one of my most memorable school days that until today (we celebrate our 25th high school reunion next month), I still remember sea urchins belong to the Echinodermata phylum.
