  • Christian Saa

    Undersea Specialist
    Christian was born on the island of Isabela in the Galápagos archipelago. He grew up on a farm and had a magical childhood devoid of cars, electricity, telephones—just pure nature and playful sea lions along the beach. At the age of seven, he moved with his family to Santa Cruz Island, the economic hub of the Galápagos Islands. His father began to work in tourism and took Christian around the islands during school vacations. It was during this time that Christian learned to love and understand the real value of this unique archipelago, and he decided to devote his life to its stewardship. A lifelong passion for nature and its creatures took root in his heart, and he eventually decided to become a naturalist, which he has now been doing for 18 years now.

  • Paula Tagle

    Expedition Leader
    Paula grew up in Guayaquil where she obtained an undergraduate degree in geology from the Polytechnic University of Guayaquil. She enjoyed many field trips all around Ecuador and during her vacations traveled in Central and South America in the hope of learning more about her people and culture. The last year of her studies she worked at a mine looking for a more ecologically responsible way of recovering gold. Interested more in volcanoes than in raw materials, she came to Galápagos, a mecca for geologists, in 1992. She was bewitched by the other wonders of the islands and became a naturalist guide for the Galápagos National Park.
