Sea snakes can be assigned as a slayer task by Vannaka at level 40 Slayer, level 50 combat and with the completion of Royal Trouble. They are found in the Miscellania and Etceteria Dungeon, which can be entered during and after the Royal Trouble quest. They attack with melee and are poisonous so antipoisons of any variety are strongly recommended. Both variants share the same drop table, although the hatchling drop regular bones whereas the young drop big bones (and by extension long and curved bones).
