Wildlife, Wild Lands: Weekly Expedition Shots (PHOTOS)

Our exclusive Expedition Photography program lets you travel aboard the ships of the Lindblad-National Geographic fleet, explore remarkable geographies -- and have professional photographers at your side and at your service. Besides helping guests with camera settings and ensuring they go home with great photos, these specially trained naturalists often send back some of the expeditions' finest images. Those are combined with shots from our expeditions leaders, other naturalists, guests, and National Geographic Photographers for our Photos of the Week.

This week our photos come from Galápagos, the Amazon, Antarctica, New Zealand, Costa Rica and Baja California.
