Unless there's a different one, I've always thought that when folks around here say "Sand Shark" or "Mud Shark", that they are actually referring to Spiny Dogfish.

Out in MA9 last week every king we brought up would have six or eight doggies following it all the way to the net, and they were not small ones...several in the 4 foot plus range every time.

If you were unlucky enough to hook a bullhead or flounder, the sharks would be on it in a few seconds if you didn't immediately get it up and off the hook, and several times we reeled up dogfish hooked on the back of flounder, reeled 'em both up.

More often we just reeled up the back half of a flounder.

Fish on...
