Discovery Channel’s “Shark Week”, hosted by Andy Samberg, begins tonight on the Discovery Channel. “Great White Invasion” airs at 9pm, followed by “Jaws Comes Home” at 10pm.

“Great White Invasion” will follow Chris Fallows and a team of scientists who are trying to figure out why white sharks are “suddenly” being seen “in large numbers” among swimmers and surfers along the coasts of South Africa, Australia, and California.

“Jaws Come Home” documents researcher Greg Skomal’s 2010 tracking study of five Atlantic white sharks tagged off of Chatham, Massachusetts. Skomal’s goal is to better understand the sharks migration up and down the eastern coast of the U.S. through tracking data obtained from satellite tags.
