Bottlenose Dolphin

These dolphins are a common sight for fishermen and seafarers, and are generally considered good luck. Known for their friendly nature and intelligence, and have been known to help swimmers in distress. Dolphins are smart enough to recognize individuals as well as individual ships, and those who offer hostilities will seldom see these creatures again, unless from afar. Bottlenose dolphins may grow up to 13 feet in length, and weigh an average of 660 pounds. Because they navigate with echolocation, dolphins can easily detect invisible creatures in the water.
