Secrets of Giant Sharks

Sorry, there are no airings at this time. Please check this page for future updates.

The two biggest fish on the planet - the whale shark and the basking shark are instantly recognizable yet until now we have known virtually nothing about their lives. All our knowledge of them has been based on encounters at the ocean surface; once they disappear back below the waves the lives of these giant sharks have been total mysteries to us.
