They are small brown creatures about the size of a grain of rice. The look like a cross between a seaworm and a shrimp ( meaning they show body features of both) they can be found on bass of all sizes and are not, to my knowledge, detrimental to the basses health. They are most prevalent on fish in large schools and if you are catching bass with lots of lice it means there are a lot of fish in the area you picked to fish. ( lucky for you). I have seen bass by the thousands on flats in Cape Cod Bay and at Monomoy rolling in the sand ridding themselves of them. I look on sea lice as a good sign when they are found clinging to the bass's body as I beach it or lift it over the gunwale of my boat and the more there are 9 times out of 10 means there are more fish to be had. Hope that helps, Flap.
