    A team of marine biologists, ecologists and naturalists will guide your adventure with outstanding commentary about local environment and sharing real-time insight into whales’ ecology and behavior while collecting scientific data for on going research and conservation projects.

    During our encounters we may observe whales spouting while cruising along, or powerfully breaching and tail slapping while playing or fighting. It is breeding season in the Mexican Pacific so there is a lot going on! If lucky enough, we may find females nursing their calves, or maybe listen to the intriguing songs performed by males as part of their courtship ritual.

    By taking part on this expedition you are contributing directly to marine research and monitoring activities led by Onca Explorations and its partners for the conservation of whales and dolphins in this important region of the Mexican Pacific and Gulf of California.

    primera recaptura MZT0066By taking photographs of natural markings, like nicks and scars on dolphins´ dorsal fins, or the pigmentation pattern found on the flukes of humpback whales, cetaceans can be identified to the individual level, in the same way fingerprints are used on humans. By building photo-identification catalogues, comparing them with those collected at different geographic regions, we can begin to better understand the dynamic lives of whales and dolphins, including movement patterns, frequency and duration of their associations, patterns of residence and their abundance in the study area.This information is crucial for the development of proper conservation and management programs for all species.
