It is a well-known fact that sharks inhabit the sounds of North Carolina and Long Island. While there are several species of sharks that occasionally wander into these waters, only a few are regularly found in the area. These include the sand tiger shark, the sandbar shark, the spiny dogfish, and the smooth dogfish. In addition, larger species such as the Great White shark have also been spotted in the Long Island Sound, although they are less common. Shark attacks in these areas are very uncommon and non-fatal, with most sharks having no interest in interacting with humans.

What You'll Learn
Shark species in the sound
Sharks are present in the sounds, estuaries, and ocean waters in and around North Carolina, providing a variety of habitats for these water-dwelling species. Most sharks found in the sounds of North Carolina are transient, moving through the estuary to feed or migrate. However, some species use these sounds as nursery habitats, and their young may remain for several months. Here are some of the shark species found in different sounds:
Long Island Sound
Long Island Sound, located between Connecticut and Long Island, is known to have sharks. While most species are generally harmless to humans, there is always a slight chance for a "maneater" to show up. Some of the shark species that have been reported or speculated to be in the area include:
- Sand tiger shark
- Sandbar shark
- Spiny dogfish
- Smooth dogfish
- Blue shark
- Mako shark
- Hammerhead shark
- Thresher shark
Puget Sound
Puget Sound, located in Washington, is home to several shark species, although they are less frequently observed in the inland waterways compared to the coast. Some of the shark species known to inhabit or occasionally visit Puget Sound include:
- Catsharks
- Sixgill sharks
- Sevengill sharks
- Soupfin sharks
- Salmon sharks
- Leopard sharks
North Carolina Sounds
The sounds of North Carolina, including Pamlico Sound, Core Sound, and Albemarle Sound, are home to a diverse range of shark species. Some of the shark species commonly found in these waters include:
- Blacktip shark
- Bonnethead shark (a small member of the hammerhead shark family)
- Bull shark
- Smooth hound shark (also known as smooth dogfish)
- Sandbar shark
- Atlantic sharpnose shark

Shark behaviour and habitat
Sharks are found in all seas and are commonly found at depths of up to 2,000 metres (6,600 ft). They generally do not inhabit freshwater, although there are some exceptions, such as bull sharks, river sharks, and Ganges sharks, which can survive in both seawater and freshwater or just freshwater, respectively. The size of sharks varies greatly, from the dwarf lanternshark, a deep-sea species that grows to only 17 centimetres (6.7 inches) in length, to the whale shark, the largest fish in the world, reaching approximately 12 metres (40 ft).
Sharks are usually solitary creatures, swimming and hunting alone most of the time. However, they do come together in certain situations, such as mating or when there is an abundance of food. Some shark species exhibit a social structure based on groups called "schools". Hammerhead sharks, for example, have a clear hierarchy and often swim together in groups. Sharks with similar sizes tend to stay together, as larger sharks prey on smaller ones.
Sharks primarily use their chemical senses, particularly smell, to locate food. They have well-adapted visual acuity for close and long-range location and can distinguish moving objects by reflection rather than colour, in both dim and bright light. They also possess pit organs that act as distance touch receptors, responding to sound waves and allowing them to navigate through acoustic orientation. Additionally, they can detect minute electrical activities, which may be used to locate live prey just before they capture it.
Sharks have various hunting strategies depending on their species and the type of prey they seek. Benthic sharks, for instance, camouflage themselves on the ocean floor, waiting for prey to come close enough for them to attack from below, sometimes swallowing their prey whole. In contrast, pelagic sharks must approach cautiously and quickly before their prey is aware of their presence. Large predatory sharks may wait for their prey to bleed out before feeding, and they only feed a few times a week. Smaller shark species, on the other hand, feed more frequently throughout the day, as their prey are also smaller. Sharks may also form large groups to hunt and capture larger prey cooperatively, although this behaviour is rare.

Shark attacks
Sharks are present in the Long Island Sound, and while it is uncommon for them to attack, it is not impossible. The presence of shark species in the area, such as the sand tiger shark, blue shark, and sandbar shark, serves as a reminder to exercise caution when in the water. These species are known to inhabit the waters of Long Island Sound and have the potential to pose a danger to humans. However, it is worth noting that most sharks are not interested in humans and are simply passing through or using the area as a nursery habitat for their young.
The warming waters of Long Island Sound and the resulting impact on shark prey species may also influence shark behaviour. As the waters warm, sharks may be drawn closer to shore in search of food, increasing the likelihood of human-shark interactions. Additionally, certain shark species exhibit specific migration patterns, with some travelling further north during the summer and south for the winter. This seasonal movement can bring them closer to populated areas, increasing the potential for human encounters.
While shark attacks are rare, it is always advisable to take precautions when swimming or engaging in water activities in areas known to be inhabited by sharks. Being mindful of their presence and taking appropriate measures, such as avoiding areas with seal populations or staying in groups, can help reduce the already low risk of a shark attack. Additionally, staying informed about shark species and their behaviours can further enhance safety. By being aware and informed, individuals can safely enjoy the waters while respecting the natural habitat of these fascinating creatures.

Shark fishing
In terms of equipment, it is important to use the right gear for the size of shark you are trying to catch. For smaller sharks, a medium-heavy action rod with a 5000 reel is a good starting point. For larger sharks, extra-heavy rods with reels around the 10,000 size are required. Braided line and small, high-performance reels are now commonly used for shark fishing, as they allow for more control when setting the hook and reduce fight times. A strong metal leader is also essential to prevent the sharp teeth of a shark from slicing through your line.
When it comes to bait, live bait such as ladyfish, mullet, threadfin, mackerel, and squid are all effective options. Sharks will also take dead bait, with fresh dead baits being the most successful. Anything with a strong odour or chunks of meat hanging off will attract their attention. Artificial lures such as topwater, paddle tails, and bucktails can also work well, as the flashy movements and sounds entice sharks to bite.
In terms of technique, finding the right location is critical. Sharks can often be found around structure, such as ledges, holes, and wrecks. Setting up a chum slick can also help attract sharks, and using buckets of chum can create a constant flow to draw them in. Drift fishing is another effective method, allowing anglers to cover more ground and locate sharks by observing the behaviour of birds and smaller fish.
It is important to be aware of local regulations and laws when shark fishing. Some areas may prohibit the use of certain types of bait or require special permits for shark fishing, especially in areas close to public beaches. Anglers should also be mindful of the need to release prohibited shark species immediately and use specific types of hooks to minimise harm to the sharks.

Shark migration
Climate change is causing tiger shark populations to shift northward. A NOAA Fisheries study found that tiger sharks are migrating into northern latitudes earlier and expanding their movements further north due to ocean warming. This large-scale northward expansion is driven by the overall warming of the U.S. Northeast Continental Shelf Large Marine Ecosystem. Tiger sharks are a highly migratory species with a distribution that stretches from Cape Cod, Massachusetts to Florida and the Gulf of Mexico. They prefer warm waters (roughly 72 degrees Fahrenheit or 26-28 degrees Celsius) and are not targeted commercially in U.S. waters, but they can be caught as bycatch.
The study used satellite telemetry data from the University of Miami and remotely sensed environmental data from NOAA CoastWatch to investigate changes in tiger shark seasonal distribution. The data showed that for every 1-degree increase in sea surface temperature anomalies, tiger sharks arrived in northern waters 14 days earlier and extended their movements farther north by nearly 4 degrees of latitude. This shift in migration timing and distribution has left tiger sharks more vulnerable to fishing.
The capture data also showed progressively earlier tiger shark catches in northern waters across years. The northern edge of high-catch density areas shifted north during the warm seasons by more than 400 kilometers since the 1980s, paralleling a shift in their preferred temperature range. Increasing water temperatures have shifted tiger shark movements beyond management areas closed to longline activities, increasing their vulnerability to fisheries.
Climate change is having a significant impact on tiger shark populations and their migration patterns. The warming of the oceans is causing tiger sharks to expand their range and move into new areas earlier in the year. This has exposed them to greater risks from fishing activities and longline fisheries. The earlier arrival and extended movements of tiger sharks into northern latitudes due to climate change highlight the complex ecological impacts of rising ocean temperatures.
