Dolphins become agressive in packs the same way Wolves and Zombie Pigmen do.
Polar Bears will get angry if you get to close to their cubs.
When Dolphins are fed Raw Cod or Raw Salmon, they swim to the nearest Shipwreck or Ocean Ruins. Because they are locating the Chest in the structures rather than the structures themselves, breaking the Chests causes the Dolphin to locate a new structure with intact Chests.

Dolphins cannot survive without getting air every once in a while, so if they stay submerged for about four minutes they begin drowning.
