Dolphin

Like many other aquatic beasts, whales come in many shapes and sizes. The smallest whales are the dolphins. Known for their extremely friendly personalities, is not uncommon for these beasts to approach humanoids out of curiosity and attempt to play harmless pranks or games with them. They also have even been known to aid individuals stranded amidst the waves from shipwrecks or pulled out by the tidal current. They are also a welcome presence along any coast as their pods tend to drive out larger, more dangerous aquatic predators. Despite being smaller than most aquatic threats, dolphins use their agile speed and coordinated tactics to harry its opponent until it flees.
