6 1740- Two Gray Whale which were probably nursing their 1800 calves were observed inside Pt. Conception. Both whales were noted in stationary positions. Each would breathe three or four times on the surface, then roll over on their sides. In this position the flipper and sometimes the flukes showed... The distance between us and the whales prevented us from noting any young. 28 March 1968 1115 Eumetopias - 2 Steller sea lions Both were floating on their backs with one front flipper and both rear flippers out of the water. 1205 Callorhinus - 1 Northern Fur Seal 1245 Callorhinus - 1 Northern Fur Seal 1515 Delphinus - ca. 50 Common Dolphins Maximum of ca. 12 were riding the bow at any given time. All appeared about the same size (adults). One large specimen (girth) was noted to be probably pregnant. Some of these dolphins had the grayish patches in the dorsals. DeLong and Brownell attempted to collect specimens but were unsuccessful. 1517 Callorhinus - 1 Northern Fur Seal 1540 Delphinus - ca. 40 Common Dolphins Dolphins were noted of various sizes, usually young and adults. All dorsal fins noted were dark in color. All other body colors appeared darker than other Delphinus we have noted. One outstanding dolphin was noted with a large patch of "white" posterior to the dorsal and one-third of the way down the side. Brownell attempted to collect the above dolphin without any luck. 1517- Callorhinus - 1540- Several large groups of smaller cetaceans were noted. 1606 As we approached, three groups were distinguished: first, dolphins jumping clear as they moved along; second, dark animals, whitish underside, jumping like Tursiops straight up out of the water, falling back into the water on their sides; third, large dorsal fins like female Orcinus.
