Curious companions

Meet Finn & Bertie

Our two resident sharks, joining us for dives, discoveries, films and the very long adventure of building a submarine.

The curious one

Finn

Finn wants to know what's hiding under every rock, inside every wreck and beyond every patch of seaweed. He loves marine life, strange underwater discoveries and finding out how things work.

The adventurous one

Bertie

Bertie is always ready for the next dive. He likes cameras, exploring new places and ambitious ideas — including the rather enormous challenge of building a submarine. Enthusiastic, occasionally a little too confident, and a firm believer that the best adventures start by going a little deeper.
