Stewart, Pieter A. Folkens. Whales California Channel Pvgmy sperm whales, Kogia brevueps (Blainville, 1838), have been reported from Washington south to (and into) the Sea of Cortes. Along the California coast they have stranded at Imperial Beach, Mission Beach, Del Mar, Balboa, and Cabrillo Beach. They have rarely been seen and positively identified alive (although the frequency of strandings suggests they may be more common) and it is generally believed that they remain habitually seaward of the continental shelf FIGURE 44. Neither pv^mv nor dwarf sperm whales are likelv to be seen very ofcen in the SCB. Both are secretive inhabitants of the open sea and .ire detected even by experienced observers only under exceptional circum- stances.

Dwarf sperm whales, Kogia simus (Owen, 1866) are known from south (the Pacific coast of southern Baja California) and north (San Luis Obispo County and British Columbia) of the SCB, but like the pygmy sperm whales are believed to be primarily creatures of the open sea. There are no confirmed records of dwarf sperm whales from within the SCB. Both species of Kogia feed on cephalopods and shrimp. The proba- bility that either will occur in the SCB is highest in years and seasons when pelagic squid are present in substantial numbers, as was true in the late 1970s and early 1980s; otherwise, neither is likely to be seen inshore of the continental Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrat
