We know we have a few in our boiling pots so here's a few facts about it.
Ever see a crawfish like this one before? It almost looks like he escaped from our ponds, made his way to saltwater, and got covered in barnacles!
Actually, it’s not all that unusual to find some of these “crusty crustaceans” in our traps this time of year. (And don’t worry, the dirty appearance isn’t harmful and doesn’t affect the taste of the crawfish at all.)
What you’re actually seeing on this crawfish are the eggs of an insect known as “water boatman.” According to the LSU AgCenter, the water boatman eggs are laid on newly molted crawfish and are usually most abundant on the head and below the eyes. ...
It's late in the season, so growth of the crawfish has stopped, meaning they are no longer molting "shedding" their old shells. Without molting, anything that attaches to their shell will stay on their shell upon being caught. This is not seen earlier in the season because the crawfish are constantly growing and molting.
