Other than this being an impressive silver cabazon that is...

The cabezon is guarding eggs (lower right, lower center). This is the season for that behavior. They can be quite approachable if you take your time.
However, they can also get defensive. I once had one chomp on my arm while I was trying to take pictures. No damage done to me or drysuit,
but it was quite surprising.

Nice shot. I didn't even notice the eggs. Thanks for sharing

This aggressive behavior is interesting. I had one come after my yellow octopus hose one time!

We have a local site called the Edmonds Underwater Park (or Bruce Higgins Underwater Trails, depending on whether you want the official name or what everybody calls the place). It is a haven for cabbies, and it's an entertaining site to dive in the winter. I can remember floating slowly up the hull of a scuttled pleasure boat, with the intention of checking out the cabin for critters, and as I came to the rail a cabezone about a foot long came streaking toward me. He hit me in the shoulder, and grabbed the outer, Lycra skin of my Fusion dry suit. I looked down, and here was this little fish, hanging on for dear life and tugging on my suit. I whacked him with my hand, and he let go, only to come charging back and grab me again. I was laughing so hard I almost choked myself. They are the Jack Russell terriers of the fish world -- at least, of the cold water world!

Normally, they aren't aggressive, and you can take pictures like:

TSandM had a funny encounter with a little one; my daughter had a funny encounter with a gigantic one. We were doing Edmonds and she happened upon a cabbie close to three feet long, guarding eggs. He charged at her full tilt twice, and only veered off when she shoved her light in his face. In our experience, cabezons are the rhinos of the Pacific: they don't necessarily bite, but they'll ram the crap out of you!

Jeff Laity had quite an encounter at the oil rigs once.
