Britain's Secret Seas: Giants of the West

INHALT

Revealing the stunning marine life, mysterious wrecks and issues that affect our seas. The first programme uncovers the world of the giants that reside in and on our Western seas. A few metres off the Cornish shore, the team study Britain's largest fish, the basking shark. Despite the fact that they grow up to ten metres long, little is known about them, which makes effective conservation very difficult.
