Hagfish have an unusual strategy for survival. This sea creature oozes lots of gross, sticky slime! The goo covers the enemy so it can't breathe. The enemy either dies or struggles to swim away. Once the hagfish is safe, it ties its long, thin body into a knot to scrape off the extra gooey slime. These are just some of the fascinating facts kids will discover as they explore the world of these disgusting animals. Large, eye-popping photos and clear, grade-appropriate text engage emergent readers as they learn all about the unique and gross ways hagfish protect themselves. A section in the back of the book profiles another animal that protects itself in a similar way, to help reinforce the concept of defense mechanisms.
