Yesterday I was at Cavallo Point where I saw a Black-Crowned Heron catch a Monkey Face eel in the rocks.  I had no idea of the abundance of sea life there until I watched a video on poke poling in the rocks.

It took some time for the Heron to swallow the eel, so one gull, and then, two, came in to offer help.  There was an interesting scuffle but the Heron held on, and eventually gulped down the whole, juicy, eel.
