Its probably the best worm bait around if you can get it,it keeps the same as Rag worm,probably a week or so in a fridge or keep them in a tank with sea water and a pump with regular water changes if possible,if they are snakes use them as your main presentation of bait and use something else to tip your bait off,mussell,Mackerel or crab.make sure the area you want to fish is producing fish as Whites are expensive to buy and its a shame to waste them.IMO
