Pacific Cod (True cod) = Gadus Macroephalus can reach 119 cm (46.9 in)

Pacific Tomcod = microgadus proximus can reach 30.5 cm (12 in)

And, Tomcod do have the whisker. I remember them looking like "minnie me" versions of True cod.

I do remember the unique "google eyes" of the Walleyed Pollack.

Hake were harder to tell apart from True cod, although usually smaller, if memory serves me correct.

I think "Krab" is made from either pollock or hake.
