Don't play with the eels!

- The topic of this chapter is eels.…Unlike the snakes they resemble,…eels are actually a variety of fish,…which means that they're fast swimmers and they have gills.…But unlike other fish, they have to constantly…open and close their mouths to force the water…through their gills, which gives them a menacing appearance.…Now, in this chapter, we're gonna develop…this image right here, and then we'll create…a six-second looping movie, shown here…as an animated GIF file, and here on the website Vine.…So keep watching.…

This is going to be fun.…
