"This is a shark that can grow upwards to five feet in length" – Jeff Corwin and "friends" visit "Piers Morgan Live"

With the fascination that is the phenomenon of "Shark Week" set to offer it's annual airing next week, on Friday evening "Piers Morgan Live" offers a bit of a preview, as Jeff Corwin – and a tankful of his teethy friends – joins the program in studio.

An animal and nature conservationist, tonight Corwin introduces Piers Morgan to one member of the Animal Kingdom that makes its home not too far from the program's Manhattan studios:

"This is a shark that you can see right here, along the coasts of New York. This is a shark that can grow upwards to five feet in length," he explains, speaking of the spiny dogfish, or spiny shark. "When this animal was born, I don't think people realize this, but this is a creature that actually began its life in its mother, not as a free-formed egg that was laid in the nest. It actually, uh, was attached to a yolk sac and the mother gave birth to it. And she had maybe four or five."

Perhaps best known for his work as the host and executive producer of his two Animal Planet programs, "The Jeff Corwin Experience" and "Corwin's Quest," tonight's guest goes on to offer more information regarding the life cycle and birthing details of his living, breathing visual aids:

"As I said with the great white sharks, these animals can have a number of babies in them and they'll actually - when they come into the world, after many months of...this pregnancy - they'll come out with the battle scars. And some sharks will never even get a chance to get out," he reveals. "They're actually eaten in utero."

Watch the clip as Corwin goes on to answer Morgan's most-pressing question – "How dangerous would that shark be?" – then tune in to CNN at 9 for a program dedicated to not only sharks, but also snakes, and alligators.
