Our First Week with the Spotter Airplane Supported in the Sea of Cortez!
We were fortunate enough this first week to find whales pretty much every day: pairs of mother and calves of humpbacks breaching out and playing, blue whales, fin whales, and even a gray whale! Aside from these, we were surprised to have found a couple of pregnant whale sharks as well! Pods of dolphins and mobulas aggregations are in our daily sightings.
