A freeper wants to know if they only get ONE bab for their lifetime or if they grow a new one if they shoot their original....do you know??

Some of them have several at a time. They do shed them, whole, from time to time, as well - but have a new one in place when that happens.

The ones at the aquatic petting zoo have them pulled out with pliers and then new growth is trimmed back like toenails, according to the spokesperson I saw for a local aquarium.

The barb, or spine, according to Dr. Shipp, can grow back if broken off, and is actually a modified scale, armored with recurved serrations that are as sharp as razors.

Ther barb is not actully the "tail" part of the ray which you are probably familiar with and is actually soft and pointed.

The barb grows our from the base of the tail and is usually hidden.

It does grow back.
