I humbly disagree. I spent my youth on the docks catching Tom Cod. They look just like a small Pacific Cod. There are two types of Tom Cod Microgradus tomcod, and Microgradus proximus.

Greenling, Hexagrammos decagrammus, look like, well ,greenling, or if you have enough imagination perhaps lingcod, but to me they do not look like Tom Cod . Also note the male and female kelp greenling look quite dissimilar
