Charleston Harbor, A Biodiversity Treasure

Uncover Charleston Harbor's abundant biodiversity and marvel at its wildlife and marine life wonders with CHS Cruises.
Charleston Harbor is one of the most biologically diverse waterways in the United States, home to a wide variety of wildlife and marine life. From bottlenose dolphins to loggerhead sea turtles to endangered bird species, the harbor is a treasure trove of biodiversity.


One of the most iconic residents of Charleston Harbor is the bottlenose dolphin. These intelligent creatures are a common sight in the harbor’s waters, often seen swimming alongside boats or fishing vessels. One of the best ways to see bottlenose dolphins in Charleston Harbor is by taking a dolphin-watching tour. These tours offer an up-close and personal experience with these fascinating creatures, highlighting their natural behaviors and educating visitors about their biology and conservation.


Another famous resident of Charleston Harbor is the loggerhead sea turtle. These gentle giants are one of the largest sea turtle species in the world, and Charleston Harbor is home to one of the largest populations of loggerhead sea turtles in the United States. These gentle giants can often be spotted swimming in the harbor’s waters or basking on the shore. Visitors should take care to avoid disturbing sea turtles and their nests, which are protected by law as they are on the endangered species list.


Charleston Harbor’s marshes, beaches and wooded areas are home to a diverse range of bird species, from majestic raptors to delicate shorebirds. This makes the harbor an ideal place for bird watchers and nature enthusiasts alike.Some of the more prominent birds you will see in the harbor are the Brown Pelican which can be seen diving for fish, Great Blue Heron standing silently in all its grandeur, and Ospreys can be seen soaring overhead or perched on a nest. Other birds in the area include egrets, ibises, gulls, terns, kingfishers, and many others. The harbor is also home to some very endangered birds, including the Red Knot and Piping Plover, which use the shorelines for nesting.


A very diverse collection of fish species can be found in the harbor. With rocky jetties, marshy creeks and shallow flats, this area supports a wide range of fish, including Redfish, Speckled Sea Trout, Flounder, Black Drum, Sheepshead, Spanish Mackerel, Bluefish, King Mackerel, Cobia, Tarpon, Sharks, Striped Bass, Weakfish, Atlantic Croaker, and Spot.


Two rarer sights are the Atlantic Bottlenose Whale and Manatees. Both of these creatures can be seen in the harbor but only rarely. The Atlantic Bottlenose Whale is an infrequent visitor but can be seen in the winter months on rare occasions. Manatee encounters are even rarer as Charleston Harbor is north of their usual migration route. However, some boaters are the lucky ones to spot these gentle creatures.


Charleston Harbor is a thriving ecosystem that supports a wide range of marine life, including fish, birds, sea turtles, whales, and other species. However, due to human impacts, this precious habitat faces many threats, including pollution, habitat loss, and overfishing. One of the primary conservation efforts in Charleston Harbor is reducing plastic pollution. Conservation efforts, such as beach cleanups and habitat restoration projects, are essential to preserving the rich biodiversity of the harbor and protecting its unique inhabitants.
