I just got into Jabu-Jabu's belly, and there's annoying enemies all over the place. Jellyfish are only one among them. Two others I've seen are bubbles and floating lamprey-ish guys. If I attack any of them with my sword, I take damage. They are all immune to my slingshot.
How do I deal with these enemies?

Wipqozn has it right. Use the boomerang.
However until you get the boomerang, you should be able to fight them with deku sticks. Also using the magical charge attack seems to work.
