They take extra damage from tridents enchanted with Impaling,[until JE Edition Combat Tests] and, except axolotl, do not cause pufferfish to inflate nor take damage from them. All aquatic mobs except dolphins are immune to drowning, and all except guardians, elder guardians, and turtles take suffocation damage if out of water for too long. Aquatic mobs have the ability to swim, whereas other mobs simply float on water or sink. In Bedrock Edition there is no in-game classification for these mobs.
