Connecticut may not be the first place that comes to mind when thinking about dolphin sightings, but it is actually home to nine different types of these intelligent and majestic creatures. From the alluring Atlantic Spotted Dolphin, comfortable in both deep and shallow waters, to the acrobatic Spinner Dolphins known for their impressive displays, there is a diverse range of dolphins to be found off the coast of Connecticut. The Striped Dolphins make a statement with their striking color pattern, while the elusive Clymene Dolphins remain a mystery, as little is known about them. Long-beaked Common Dolphins showcase their acrobatic swimming in shallow waters, while their short-beaked cousins form large pods and are highly adaptable. The Bottlenose Dolphins, perhaps the most well-known species, can be found in a wide range of environments. On the other hand, the Rough-toothed Dolphins prefer warmer waters and are known to be less playful compared to other dolphins. Lastly, the shy and reserved Harbor Porpoises often form small pods and are frequently bullied by their dolphin counterparts. With such a rich variety of dolphins calling Connecticut home, there is much to discover about these fascinating marine creatures.
