Minecraft wiki entry for Mob, associated text: This group of mobs includes drowned, husks, phantoms, skeletons, skeleton horses, strays, withers, wither skeletons, zoglins, zombies, zombie horses, zombie villagers, and zombified piglins. These mobs are damaged by potions of Healing, healed by potions of Harming, and are immune to drowning (except for husks and zombies, which turn into zombies and drowned if drowning, respectively) and poison damage. Zombies, zombie villagers, drowned, skeletons, strays, and phantoms burn when under direct sunlight, unless they are touching water or wearing a helmet. Under the fire resistance effect, undead mobs still catch fire in direct sunlight but do not get hurt by the fire. All undead mobs except for drowned, phantoms, and withers sink in water. All undead mobs take extra damage from weapons enchanted with Smite, and are ignored by withers.
