Dolphin

Dolphins are one of the most intelligent aquatic animals of Azeroth, surpassing even many murlocs. They are found all across the seas, mostly in shallows on the continental shelves. Depending on where they live, their coloration changes, but they are generally gray with dark backs. Their diet is very wide, including fish, squid, crustaceans, and small thrashers. Many druids choose dolphins as their aquatic forms.

Behavior
Dolphins are well known for their agility and playful behavior, making them a favorite for hunters and pet-tamers. They will often leap out of the water to follow ships. They are a very social animal and live in large groups, using synchronized movements to herd and hunt fish. Dolphins will also follow seabirds, whales, and fishing vessels to feed opportunistically.

Aquatic Form

While it is generally known that druids turn into sea lions or orcas, there are a select group of druids who prefer to use a dolphin. In this form, they are able to manage very high speeds and can communicate with wild animals. The downside of this form is that it has no defensive capabilities aside from a hard, bottled nose. Outside of combat though, it has a large number of potential uses. Its speed is nearly unmatched, allowing druids to cross large pools of water in seconds, and gives the Alliance and Horde a greater presence in rivers and bays. In situations of great distress, a druid can transform into a dolphin and leap to a rapid escape.
