Dolphins are hostile prey in Hungry Shark World.
Dolphins will attack the player's Shark if you approach them. They appear in the Pacific Islands map and the Arabian Sea. They are located near the Island of Heads and the Aircraft Carrier in the Pacific Islands map, and the golf course in the Arabian sea and can only be eaten by Tier M and above. Dolphins spawn in groups of 10 so it's dangerous for small sharks and the Blacktip reef to approach dolphins.
