Humpback Whale Underwater Bubble Streaming Among Rowdy Groups in Hawaii

During the years I worked for Dan Salden and Hawaii Whale Research Foundation studying humpback whales (Megaptera novaeangliae) in Hawaii, we usually looked for surface active groups ("rowdy groups") when possible, since these groups offered the greatest potential for collecting the social affiliation information that was the focus of Dan's…

California Sea Lions, Coronado Islands, Mexico

Some of my favorite diving with California Sea Lions (Zalophus californianus) has taken place at Mexico's Coronado Islands (Islas Coronado). The Coronados are a small group of undeveloped rocky islands just offshore of Tijuana, Mexico and only about an hour boat ride south of San Diego. Seemingly barren, the islands…

Killer Whales (Orca) attacking California Sea Lion

I saw Wild Kingdom in action yesterday: killer whales preying upon California sea lions. Classified as Biggs transient orcas, these individuals are well known (CA51) for terrorizing other marine mammals along the Southern California coast. "Biggs transients" are one of four distinct populations (some insist they are species) of killer…

Whales at the Coronado Islands, Mexico

Whales visit the Coronado Islands in Mexico throughout the year. During winter months, gray whales (Eschrichtius robustus) pass by the islands, first southbound and a few months later traveling north, during their annual migration between Baja California and the Bering Sea. Fin whales (Balaenoptera physalus) and blue whales (Balaenoptera musculus)…

Gray Whale Aerial Photos, Eschrichtius robustus, California

Gray whales (Eschrichtius robustus) migrate from the Bering Sea in Alaska down the west coast of the United States to the "calving lagoons" of Baja California. (A small number of grays whales also live in the extreme western Pacific.) This migration is considered the longest of any mammal. Calves are…

Humpback Whale Breaching Near San Diego

Humpback whales (Megaptera novaeangliae) are found throughout the worlds oceans, but seeing them near San Diego is somewhat unusual. Conventional wisdom has it that humpback whales in California are most often seen in the Channel Islands near Santa Barbara, as well as the central coast near Monterey Bay. However, if…

Photos of Humpback Whale Bubble Displays

Humpback whales are famous for their use of bubbles to "net" prey, especially in Alaska where coordinated bubble netting among groups of humpback whales is often seen. However, humpbacks also commonly use bubble displays and air releases in their social interactions in warm waters. It is thought the these bubble…
