Animorphs suspicion book 24 inside cover anteater

Cassie in giant anteater morph at The Gardens' anteater exhibit.

"An anteater is a funny-looking animal. From the end of its bushy, feather-duster tail to the tip of its absurdly long, pointed head, it was maybe four or four and a half feet long. It stood as tall as a grown man's knees. [...] But even though the giant anteater is comical, it is not helpless. I was resting most of my weight on my hind legs. I balanced on my front knuckles, the better to keep my wickedly curved scythe claws safe and sharp. [...] They're known to sleep as much as fifteen hours a day. But this was not a stupid animal. I had excellent hearing and an excellent sense of smell."

The giant anteater is the largest of all living anteaters on Earth. It was acquired by Jake, Rachel, Cassie, Marco and Esplin 9466, the latter via Alloran-Semitur-Corrass' body.


"Hey, what are we acquiring?"
"The one animal in the world that is specially designed to see, attack, and destroy creatures like the Helmacrons."
"And that animal is..."
Jake and Cassie[src]

After being shrunk by the Helmacrons in The Suspicion, Cassie asked Ax to fly them to The Gardens, where she, Jake, Rachel and Marco acquired the giant anteater, as new DNA would be unaffected the shrinkage. This technique was also copied by Esplin 9466, who acquired the giant anteater as well through Alloran-Semitur-Corrass' body.[1]


"When the Helmacrons shrank us, they also shrank all the DNA inside us. All the morphs were reduced to that same scale, right?"
"Well, it occurred to me that new DNA, newly acquired DNA, might not be shrunk. [...] At least, I hope. We should be able to acquire this animal we're on and morph it. Full size!"
Cassie and Marco[src]

The giant anteater morph was used by Cassie, Jake, Rachel, Marco and Esplin 9466 to become full-sized again after being shrunk by the Helmacrons. Since the anteater was designed to eat ants, the Animorphs used it to subdue the Helmacrons, while Visser Three used it to attack Tobias, although he was unable to kill him due to Ax's interference.[1]
