Anguilliformity

Anguilliformity is a big word that describes the way some animals move, like eels or snakes. It's all about how they wiggle and twist their bodies to move around. If you think about the way a snake moves, it will slither and twist its body to move forward or to turn. The same goes for eels, they will wiggle their whole body to move around in the water.

So when someone talks about anguilliformity, they are really talking about how some animals move by wiggling their bodies. It's just a fancy way of saying that they move like eels or snakes!
