Jawfish - Sea of Cortez. Jawfish come in all sizes and color variations. This Jawfish was a good size -- it's head was about the size of a baseball. These guys are really hard workers -- they create a burrow in the sand and then constantly work at keeping it clean. Jawfish will bring up debris in their mouths and then spit it out.
We had a bit of fun with this one by putting that shell over it's hole and watching it remove it over and over again. While that may sound a bit mean, each time it did so, it had this grin on it's face and seemed to say -- see what I just did, I'm so proud of myself.
