7 The first group noted was a group of ca. 150 mixed dolphins (Lagenorhynchus and Delphinus). These were not followed and were swimming away from the others. The second group noted was a widely dispersed school of ca. 500 Lissodelphis. These dolphins were divided into numerous subgroups of 10 to 30 specimens. Numerous different dolphins were noted jumping up off of the water, as stated above. No young were observed. Numerous different subgroups would ride the bow. DeLong shot (ca. 00 shot) and instantly killed one riding the bow. It floated a couple of minutes, then sank. DeLong then harpooned a specimen which was then brought on board. (Killed at ca. 1620). Chased animals again. They did not ride bow again, but started swimming fast and coming out of the water together. On several occasions dolphins were noted to slap the fluke on the surface of the water before diving. The third group noted was pod of ca. 100 Grampus. These dolphins also were divided into many subgroups. Numerous small (newborn) were observed. These were very gray in color (cf. Tursiops truncatus). Many of the large animals were in groups with only their heads, dorsal surfaces, and dorsal fins. The other animals were blackish in color as Globicephala. Animals were generally milling about the surface thus allowing us to study their heads, colora- tions, and sizes. None of the Grampus rode the bow, but several different groups approached within 100 to 200 feet of the ship. 1715 Lagenorhynchus - Pacific striped dolphin ca. 100 These were noted some distance from the ship. 29 March 1968 0950 Pacific Striped Dolphins - 2 (Lagenorhynchus obliquidens) Two large dolphins of this species were observed ca. one mile off Pt. Loma. The dorsal fins on both animals were greatly recurved. This is commonly observed in older dolphins of this species (Brown and Norris, 1956).
