Sea Beast

These Sea Beast are egg-laying sea creatures. They are roughly humanoid. They have grey skin, white eyes and a long tongue. They spit slimy, paralyzing venom. They can turn invisible. Their eyes close sideways and when they're invisible there is a slight blur where they are. They can jump nearly thirty feet into the air. Their venom is similar to the venom injected by ambush predators. Several characters likened them to an anglerfish.
