you guys are krilling me..

but for real, do other dolphins go by special names? or are they just dolphins -- several species, and orca's the black and white ones.. (and are them limited to arctic and sub arctic waters? or is it the antarctic they live in? i remember that their coloring makes them hard to detect in the water-- white belly looks like the sunlight above, dark back, little contrast when looking through the water from above... all better to sneak up on penguins.. (oops, i guess i answered my own question.. penguins are antarctic.. but what about auks are they arctic? )
