A new ocean phenomenon known as The Blob sends juvenile great white sharks straight into a feeding frenzy of monster 20-foot adults off Guadalupe Island. A team of shark experts dives deep to discover if the young sharks survive or become a snack.

Alison Towner has risked her life many times, tagging and studying great white migration patterns in South Africa for the past decade.
