Anderson Cooper: No "Plan B" when filming crocodiles for "60 Minutes"

(CBS News) The Nile crocodile is known to prey on humans more than any other kind of croc -- about 200 people are killed each year by these animals. But that didn't stop Anderson Cooper from jumping into the water.

He got an up-close look at the reptiles for this Sunday's "60 Minutes."

Appearing on "CBS This Morning" on Thursday, Cooper -- who has come in close contact with great white sharks for another "60 Minutes" feature -- told the co-hosts that "there was no 'Plan B'" while filming.

He joked, "Plan B was, 'this piece is going to get really interesting.'"

Cooper said that at one point in his swim with the crocodiles he encountered one face-to-face. He recalled, "I stick my hand out, plant (a metal rod with the camera attached) right in front of its face and you'll see the video."

You can watch Cooper's full "60 Minutes" report this Sunday at 7 p.m. ET on CBS. Watch Cooper's full "CBS This Morning" interview -- which includes talk about his recent kiss with Madonna -- in the video above.
