Dolphins and porpoises differ in their faces, fins, and body shapes. Dolphins have longer noses, bigger mouths, more curved dorsal fins, and longer, leaner bodies than porpoises. The Northeastern Offshore Spotted Dolphin, shown here, has a falcate, or sickle-shaped dorsal fin and light spotting on the belly.
In general, dolphins make two kinds of sounds, “whistles” and “clicks” (listen to the false killer whales on this page). Clicks are used to sense their surroundings through echolocation, while they use whistles to communicate with other members of their species and very likely, with other species too.

Feeding dolphins raw cod or raw salmon improves their "trust" and interactions with the player, depending on the amount of fish fed. When dolphins are fed raw cod or raw salmon, they swim to the nearest shipwreck, buried treasure, or ocean ruins.
Dolphins eat a variety of fish, squid, shrimps, jellyfish and octopuses. The types of fish and other creatures dolphins eat depend on the species of dolphin, where the dolphins live and the wildlife that shares their habitats.
Common bottlenose dolphins (referred to hereafter simply as bottlenose dolphins) are found throughout the world in both offshore and coastal waters, including harbors, bays, gulfs, and estuaries of temperate and tropical waters (estuaries are the areas where rivers meet the sea). They are one of the most well-studied marine mammals in the wild.
The Amazon river dolphin , also known as the pink river dolphin or boto, lives only in freshwater. It is found throughout much of the Amazon and Orinoco river basins in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela.
