Dolphin (Franchise)

Dolphins are marine mammals that are mentioned in the game, School of Dragons.

Description
Dolphins are mammals fully dependent on a water environment. They roughly resemble Fish, and were historically thought to be a fish. However, dolphins must breathe air from a nostril - a blow hole - at the tops of their heads.

The term "dolphin" is actually a somewhat loose common term applied to smaller to mid-size cetaceans. Porpoises are smaller and generally have shorter beaks, whereas Whales are much larger.

The one mention of dolphins says "Fishlegs Ingerman" wants to follow a dolphin shoal migration"''. This term "shoal" is used incorrectly here, as shoaling specifically refers to fish grouping behavior, not marine mammals. A group of dolphins is called a pod.

Function
Dolphins do not really have a function currently in the Franchise.

In actuality, dolphins have been hunted for their meat and blubber throughout history and into the present day. It is possible Vikings may have taken advantage of beached dolphins or herded them into shallow water to butcher if the opportunity presented itself. Presently, dolphins are also kept in public aquariums and zoos for entertainment.

School of Dragons
The player can send their non-active dragons on quests - called Stable Quests - for a chance at receiving rewards. One stable quest called "Faster and Slicker", asks the player to send "A fast aquatic dragon" out to study a "dolphin shoal migration" with Fishlegs.
