Delphinidae (Porpoise or/and Dolphin) 
Six animals that were not identified to species were recorded in 
the grid area. 
Delphinus delphis oairdi (Common or laird Dolphin) 
Ninety-four laird Dolphins were recorded. Fifty of these were 
in one group seen on 18 January in Santa Barbara Channel. The 
remaining lilt animals were seen in the southern third of the grid area. 
All of the animals we re attracted to the shin and on occasions a few 
rode the bow wake for a short period of time, affording excellent 
opportunity for good identification. 
Pbocoenoides dalli (Dali Porpoise) 
Three Dali Porpoise were recorded in the Santa Barbara Channel. 
1 hale so. 
Three whales were seen, one on 18. January and the others in the 
southern third of the grid, that were not specifically identified due 
to short durations of observation* 
Orcinus orca (Killer hfiiale) 
Four Killer shales were s-en on 25 January in the soutnern third 
of the grid* No disparity was noted in the size of dorsal fins, indicating 
there was no adult male travelling wi th the pod. 
Balaenoptera physalus (Fin Whale) 
Three animals were identified as possibly being of this species 
on 18 January in Santa Barbara Channel. The observer does not wish 
this sighting regarded as a positive identification. 
DISCUSSION ; 
The California Coastal marine mammals are many and varied, 
however, in the grid area which traverses water over 1000 fathoms 
or more there are fewer forms and population dens:ties are lower. Numbers 
of seasonally resident mammals do appear large enough to be considered 
important in the survey. 
Tt is interesting that we noted no Califorria Gray Whales 
( Eschrichtius gibbosus ) in the grid area during this survey. These 
animals are abundant along the coast at this time of year. They 
apparently do not warder far to sea during migration and breeding 
season.
