MARINE MAMMALS 
- by Robert ^eLong 
' One hundred fifty-five marine mar/inals of four families and eight 
snecies were recorded. Fifty-five percent of the mammals were seen 
on 18 January while in Santa Barbara Channel and beyond to D oint 
Arguello. The distribution of the mammals seen in this area would be 
considered coastal or neritic. All mammals observed in pelagic environment 
were within the grid area. Pelagic o servations accounted for of 
the total mammals seen. 
SPEC ICS ACCOUNT: 
Otariidae (Cared Seals) 
Twenty animals were recorded only as belonging to this family* 
as specific identifications were not obtained. These animals were 
probably California Sea Lions, Stellar Sea Lions, or Northern Fur 
Seal. It is possible that the Guadalupe Fur Seal occurs in the grid 
area, but populations are all small and their distribution is not well 
known. Eleven Otariidae were recorded on lC January, and nine were 
recorded in the grid area. 
Eumatopias jubata (Stellar Sea Lion) 
Two seen l8 January in Santa Barbara Channel. 
Zalophus californianus (California Sea Lion) 
Seven seen 18 January in Santa Barbara Channel. 
Callorhinus ursinus (Northern Fur Seal) 
Five animal were identified as definitely being fur seals on 
19 and 20 January. These animals were seen only in waters over a 
thousand fathoms and all were on the northern leg of the grid, it 
is orotable that other Otariidae seen in the grid were also of this 
species, but it is difficult to differentiate between females and 
young males of this species and the California Sea Lion at sea. 
Although fur seals are seldom recorded as vocalizing while 
at sea, one adult female was evoked to give two vocal responses by 
imitating the call of a fur seal pup. 
Phoca vitulina (harbor Seal) 
One Harbor Seal was seen in the Santa Barbara Channel. 
Cetacea (Whales and Porpoises) 
Seven animals were assigned only to this order on IE January.
