Despite its ferocious demeanor, the fangtooth measures a little more than 6 inches in length as an adult. Juveniles and adults look so much different that in the 1800s they were thought to be distinct species. Juveniles are found as shallow as 150 feet, migrating into the depths as they mature.

When Anastassia was flipping through an old family album, she stumbled across a photo of herself playing with her pet birds when she was four years old. In the background was another girl holding what looks to be a stuffed animal. But the crazy part is, Anastassia says there was no other little girl there when the picture was taken—well, not living at least.
