Sudden Visit | Spotted Dolphin | Port Canaveral Florida

While out fishing in 125ft of water off Port Canaveral Florida I had some visitors for a short, exciting to say the least, enjoy!
About the Species

Atlantic spotted dolphins are found in warm temperate and tropical waters of the Atlantic Ocean. They usually form groups of five to 50 individuals but sometimes travel in groups of up to 200. They are fast swimmers and often “surf” in the waves created by vessels.
Young Atlantic spotted dolphins do not have spots. As a result, they can look like slender bottlenose dolphins. Their distinctive spotted pattern starts to appear all over their bodies as they get older.
Atlantic spotted dolphins, like all marine mammals, are protected under the Marine Mammal Protection Act.
NOAA Fisheries and its partners are working to conserve Atlantic spotted dolphins and further our understanding of this species through research and conservation activities.
Population Status
NOAA Fisheries estimates population size in our stock assessment reports.
The worldwide population of Atlantic spotted dolphins is unknown. Scientists estimate that there are over 77,000 Atlantic spotted dolphins in U.S. waters.
To manage Atlantic spotted dolphins in U.S. waters, we have divided them into three stocks:
• Northern Gulf of Mexico stock
• Puerto Rico and U.S. Virgin Islands stock
• Western North Atlantic stock
Based on the most recent surveys, our scientists estimate that there are about 37,000 dolphins in the northern Gulf of Mexico stock and about 40,000 dolphins in the western North Atlantic stock. The number of dolphins in the Puerto Rico and U.S. Virgin Islands stock is unknown.
Appearance
Atlantic spotted dolphins are about 5 to 7.5 feet long and weigh about 220 to 315 pounds. They have a robust body with a tall, curved dorsal fin located midway down their back. Their beaks are moderately long. Like other cetaceans, their head has a distinctive melon, a rounded forehead that collects sounds from the environment. They have 30 to 42 pairs of small, cone-shaped teeth in each jaw.
Atlantic spotted dolphins’ color patterns vary with age and location. Young dolphins do not have any spots. Instead, they have a dark gray back with a pale white underside. This lack of spots can make young Atlantic spotted dolphins look like slender bottlenose dolphins. An Atlantic spotted dolphin starts to develop spots after its first birthday. As the dolphin matures, the spots become darker and more widespread, especially on its back.
Behavior and Diet
Atlantic spotted dolphins are usually found in groups of less than 50 individuals but sometimes travel in groups of up to 200. In coastal waters, groups usually consist of five to 15 individuals. Within these groups, the dolphins are sometimes organized by age or sex. Atlantic spotted dolphins blow bubbles through their blowholes as one way to communicate with members of their group. They also communicate with sound.
Atlantic spotted dolphins are often described as “acrobatic” swimmers, frequently leaping out of the water or jumping at the water’s surface. They can also swim very quickly and often “surf” in the waves created by vessels. They sometimes interact with other cetacean species, such as bottlenose dolphins.
Atlantic spotted dolphins can dive up to 200 feet and have been recorded holding their breath for up to ten minutes. Most of their dives are less than 30 feet and last for 2 to 6 minutes. These dolphins eat small fish, invertebrates, and cephalopods, such as squid and octopi. They have 30 to 42 pairs of small, cone-shaped teeth in each jaw. Groups of dolphins often coordinate their movements to catch prey together. Individuals sometimes use their beaks to dig into the sand on the ocean bottom to catch hidden fish.
